+                      Peer SSL Certificate Verification
+                      =================================
+
+Starting in 7.10, libcurl performs peer SSL certificate verification by
+default. This is done by installing a default CA cert bundle on 'make install'
+(or similar), that CA bundle package is used by default on operations against
+SSL servers.
+
+Alas, if you communicate with HTTPS servers using certifcates that are signed
+by CAs present in the bundle, you will not notice any changed behavior and you
+will seeminglessly get a higher security level on your SSL connections since
+can be sure that the remote server really is the one it claims to be.
+
+If the remote server uses a self-signed certificate, or if you don't install
+curl's CA cert bundle or if it uses a certificate signed by a CA that isn't
+included in the bundle, then you need to do one of the following:
+
+ 1. Tell libcurl to *not* verify the peer. With libcurl you disable with with
+    curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, FALSE);
+
+    With the curl command tool, you disable this with -k/--insecure.
+
+ 2. Get a CA certificate that can verify the remote server and use the proper
+    option to point out this CA cert for verification when connecting. For
+    libcurl hackers: curl_easy_setopt(curl, CURLOPT_CAPATH, capath);
+
+    With the curl command tool: --cacert [file]
+
+This upgrade procedure has been deemed The Right Thing even though it adds
+this extra trouble for some users, since it adds security to a majority of the
+SSL connections that previously weren't really secure.
+
+It turned out many people were using previous versions of curl/libcurl without
+realizing the need for the CA cert options to get truly secure SSL
+connections.

+
+  Many web pages do magic stuff using embedded javascript. Curl and libcurl

+
+  .pac files are a netscape invention and are sometimes used by organizations
+  to allow them to differentiate which proxies to use. The .pac contents is
+  just a javascript program that gets invoked by the browser and that returns
+  the name of the proxy to connect to. Since curl doesn't support javascript,
+  it can't support .pac proxy configuration either.
+
+  Some work-arounds usually suggested to overcome this javascript dependency:
+
+    - Depending on the javascript complexity, write up a script that
+      translates it to another language and execute that.
+
+    - Read the javascript code and rewrite the same logic in another language.
+
+    - Implement a javascript interpreted, people have successfully used the
+      Mozilla javascript engine in the past.

+
+                          How cURL Became Like This
+
+
+In the second half of 1997, Daniel Stenberg came up with the idea to make
+currency-exchange calculations available to Internet Relay Chat (IRC)
+users. All the necessary data are published on the Web; he just needed to
+automate their retrieval.
+
+Daniel simply adopted an existing command-line open-source tool, httpget, that
+Brazilian Rafael Sagula had written. After a few minor adjustments, it did
+just what he needed.
+
+Soon, he found currencies on a GOPHER site, so support for that had to go in,
+and not before long FTP download support was added as well. The name of the
+project was changed to urlget to better fit what it actually did now, since
+the http-only days were already passed.
+
+The project slowly grew bigger. When upload capabilities were added and the
+name once again was misleading, a second name change was made and on March 20,
+1998 curl 4 was released. (The version numbering from the previous names were
+kept.)
+
+(Unrelated to this project a company called Curl Corporation filed a US
+trademark on the name "CURL" on May 18 1998. That company had then already
+registered the curl.com domain back in November of the previous year. All this
+was much later brought into the lights.)
+
+SSL support was added, powered by the SSLeay library.
+
+August 1998, added project curl to freshmeat.net.
+
+October 1998, with the curl 4.9 release and the introduction of cookie
+support, curl was no longer released under the GPL license. Now we're at 4000
+lines of code, we switched over to the MPL license to restrict the effects of
+"copyleft".
+
+November 1998, configure script and reported successful compiles on several
+major operating systems. The never-quite-understood -F option was added and
+curl could now simulate quite a lot of a browser.
+
+Curl 5 was released in December 1998 and introduced the first ever curl man
+page. People started making Linux RPM packages out of it.
+
+January 1999, DICT support added.
+
+OpenSSL took over where SSLeay was abandoned.
+
+May 1999, first Debian package.
+
+August 1999, LDAP:// and FILE:// support added. The curl web site gets 1300
+visits daily.
+
+Released curl 6.0 in September. 15000 lines of code.
+
+December 28 1999, added the project on Sourceforge and started using its
+services for managing the project.
+
+Spring 2000, major internal overhaul to provide a suitable library interface.
+The first non-beta release was named 7.1 and arrived in August. This offered
+the easy interface and turned out to be the beginning of actually getting
+other software and programs to get based on and powered by libcurl. Almost
+20000 lines of code.
+
+August 2000, the curl web site gets 4000 visits daily.
+
+The PHP guys adopted libcurl already the same month, when the first ever third
+party libcurl binding showed up. CURL has been a supported module in PHP since
+the release of PHP 4.0.2. This would soon get followers. More than 16
+different bindings exist at the time of this writing.
+
+September 2000, kerberos4 support was added.
+
+In November 2000 started the work on a test suite for curl. It was later
+re-written from scratch again.
+
+January 2001, Daniel released curl 7.5.2 under a new license again: MIT (or
+MPL). The MIT license is extremely liberal and can be used combined with GPL
+in other projects. This would finally put an end to the "complaints" from
+people involved in GPLed projects that previously were prohibited from using
+libcurl while it was released under MPL only. (Due to the fact that MPL is
+deemed "GPL incompatible".)
+
+curl supports HTTP 1.1 starting with the release of 7.7, March 22 2001. This
+also introduced libcurl's ability to do persistent connections. 24000 lines of
+code.
+
+August 2001. curl is bundled in Mac OS X, 10.1. It was already becoming more
+and more of a standard utility of Linux distributions and a regular in the BSD
+ports collections. The curl web site gets 8000 visits daily. Curl Corporation
+contacted Daniel to discuss "the name issue". After Daniel's reply, they have
+never since got in touch again.
+
+September 2001, libcurl 7.9 introduces cookie jar and curl_formadd(). During
+the forthcoming 7.9.x releases, we introduced the multi interface slowly and
+without much whistles.
+
+June 2002, the curl web site gets 13000 visits daily. curl and libcurl is
+35000 lines of code. Reported successful compiles on more than 40 combinations
+of CPUs and operating systems.
+
+To estimate number of users of the curl tool or libcurl library is next to
+impossible. Around 5000 downloaded packages each week from the main site gives
+a hint, but the packages are mirrored extensively, bundled with numerous OS
+distributions and otherwise retrieved as part of other software.
+
+September 2002, with the release of curl 7.10 it is released under the MIT
+license only.

+Q: My program blows up when I run lots of curl_easy_perform() calls on a
+single thread
+Q: My program dies when a single thread re-enters the win32 select() call
+via curl_easy_perform()
+Q: --- add your own flavour here ---
+
+Single Threaded Re-Entracy
+--------------------------
+
+There is a glitch / trick to using cURL on Win32 related to re-entrancy.
+This experience was gained on verion 7.9.4 using Windows NT SP3 in a banking
+environment (just in case you wanted to know).
+
+If you have already called curl_easy_perform(), and *somehow* you cause your
+single thread of execution to make another call to curl_easy_perform() - the
+windows socket() call used to create a new socket for the second connection
+can return with 10044 / 10043 error codes.
+
+The WSA errors we experienced are:
+WSAEPROTONOSUPPORT 
+(10043) 
+Protocol not supported. 
+The requested protocol has not been configured into the system, or no
+implementation for it exists. For example, a socket call requests a
+SOCK_DGRAM socket, but specifies a stream protocol. 
+
+WSAESOCKTNOSUPPORT 
+(10044) 
+Socket type not supported. 
+The support for the specified socket type does not exist in this address
+family. For example, the optional type SOCK_RAW might be selected in a
+socket call, and the implementation does not support SOCK_RAW sockets at
+all. 
+
+We have experienced this by creating a timer that ticks every 20ms, and on
+the tick making a curl_easy_perform() call.  The call usually completed in
+about 300ms.  And we expected (before this test) that the timer would NOT be
+fired during a call to curl_easy_perform(), howvever, while the first
+curl_easy_perform() is running a tick *is* fired by the windows API somehow,
+and we then call curl_easy_perform() again - thus single threaded
+re-entrancy is achieved.
+
+Notes:
+* We made sure that a new CURL structure was being used for each
+curl_easy_perform() request, and that the curl_global_init() had been called
+beforehand.  
+* I'm happy to answer any questions about this problem to try to track it
+down.
+* Once the socket() call started failing, there is no hope - it never works
+again.
+* Slowing the timer down to give each request enough time to complete solves
+this problem completely.
+
+If anyone has the source code to the WinNT implementation of socket() and
+can figure out WHY this can occur, more tracing can be performed.

  SSL
 
+ * If you really want to improve the SSL situation, you should probably have a

+   request, this option allows you to only read the CA chain that is actually
+   required (into the cache)...
+
  * Add an interface to libcurl that enables "session IDs" to get
    exported/imported. Cris Bailiff said: "OpenSSL has functions which can
    serialise the current SSL state to a buffer of your choice, and
    recover/reset the state from such a buffer at a later date - this is used
-   by mod_ssl for apache to implement and SSL session ID cache"
+   by mod_ssl for apache to implement and SSL session ID cache". This whole

+   LIBCURL label above.
+
+ * OpenSSL supports a callback for customised verification of the peer
+   certificate, but this doesn't seem to be exposed in the libcurl APIs. Could
+   it be? There's so much that could be done if it were! (brought by Chris
+   Clark)
 
  * Make curl's SSL layer option capable of using other free SSL libraries.
    Such as the Mozilla Security Services
    (http://www.mozilla.org/projects/security/pki/nss/) and GNUTLS
    (http://gnutls.hellug.gr/)
 
+ LDAP
+
+ * Look over the implementation. The looping will have to "go away" from the
+   lib/ldap.c source file and get moved to the main network code so that the
+   multi interface and friends will work for LDAP as well.
+
  CLIENT
 
+ * Add an option that prevents cURL from overwiting existing local files. When
+   used, and there already is an existing file with the target file name
+   (either -O or -o), a number should be appended (and increased if already
+   existing). So that index.html becomes first index.html.1 and then
+   index.html.2 etc. Jeff Pohlmeyer suggested.
+
  * "curl ftp://site.com/*.txt"
 
  * Several URLs can be specified to get downloaded. We should be able to use

-.sp
-.BI "int curl_formadd(struct HttpPost ** " firstitem,
-.BI "struct HttpPost ** " lastitem, " ...);"
-.ad
-.SH DESCRIPTION
-curl_formadd() is used to append sections when building a multipart/formdata
-HTTP POST (sometimes refered to as rfc1867-style posts). Append one section at
-a time until you've added all the sections you want included and then you pass
-the \fIfirstitem\fP pointer as parameter to \fBCURLOPT_HTTPPOST\fP.
-\fIlastitem\fP is set after each call and on repeated invokes it should be
-left as set to allow repeated invokes to find the end of the list faster.
-
-After the \fIlastitem\fP pointer follow the real arguments. (If the following
-description confuses you, jump directly to the examples):
-
-\fBCURLFORM_COPYNAME\fP or \fBCURLFORM_PTRNAME\fP followed by a string is used
-for the name of the section. Optionally one may use \fBCURLFORM_NAMELENGTH\fP
-to specify the length of the name (allowing null characters within the
-name). All options that use the word COPY in their names copy the given
-contents, while the ones with PTR in their names simply points to the (static)
-data you must make sure remain until curl no longer needs it.
-
-The four options for providing values are: \fBCURLFORM_COPYCONTENTS\fP,
-\fBCURLFORM_PTRCONTENTS\fP, \fBCURLFORM_FILE\fP, or \fBCURLFORM_FILECONTENT\fP
-followed by a char or void pointer (allowed for PTRCONTENTS).
-
-\fBCURLFORM_FILECONTENT\fP does a normal post like \fBCURLFORM_COPYCONTENTS\fP
-but the actual value is read from the filename given as a string.
-
-Other arguments may be \fBCURLFORM_CONTENTTYPE\fP if the user wishes to
-specify one (for FILE if no type is given the library tries to provide the
-correct one; for CONTENTS no Content-Type is sent in this case).
-
-For \fBCURLFORM_PTRCONTENTS\fP or \fBCURLFORM_COPYNAME\fP the user may also
-add \fBCURLFORM_CONTENTSLENGTH\fP followed by the length as a long (if not
-given the library will use strlen to determine the length).
-
-For \fBCURLFORM_FILE\fP the user may send multiple files in one section by
-providing multiple \fBCURLFORM_FILE\fP arguments each followed by the filename
-(and each FILE is allowed to have a CONTENTTYPE).
-
-Another possibility to send single or multiple files in one section is to use
-\fBCURLFORM_ARRAY\fP that gets a struct curl_forms array pointer as its
-value. Each structure element has a CURLformoption and a char pointer. For the
-options only \fBCURLFORM_FILE\fP, \fBCURLFORM_CONTENTTYPE\fP, and
-\fBCURLFORM_END\fP (that is used to determine the end of the array and thus
-must be the option of the last and no other element of the curl_forms array)
-are allowed. The effect of this parameter is the same as giving multiple
-\fBCURLFORM_FILE\fP options possibly with \fBCURLFORM_CONTENTTYPE\fP after or
-before each \fBCURLFORM_FILE\fP option.
-
-Should you need to specify extra headers for the form POST section, use
-\fBCURLFORM_CONTENTHEADER\fP. This takes a curl_slist prepared in the usual way
-using \fBcurl_slist_append\fP and appends the list of headers to those Curl
-automatically generates for \fBCURLFORM_CONTENTTYPE\fP and the content 
-disposition. The list must exist while the POST occurs, if you free it before
-the post completes you may experience problems.
-
-The last argument in such an array must always be \fBCURLFORM_END\fP.
-
-The pointers \fI*firstitem\fP and \fI*lastitem\fP should both be pointing to
-NULL in the first call to this function. All list-data will be allocated by
-the function itself. You must call \fIcurl_formfree\fP after the form post has
-been done to free the resources again.
-
-This function will copy all input data except the data pointed to by the
-arguments after \fBCURLFORM_PTRNAME\fP and \fBCURLFORM_PTRCONTENTS\fP and keep
-its own version of it allocated until you call \fIcurl_formfree\fP. When
-you've passed the pointer to \fIcurl_easy_setopt\fP, you must not free the
-list until after you've called \fIcurl_easy_cleanup\fP for the curl handle. If
-you provide a pointer as an arguments after \fBCURLFORM_PTRNAME\fP or
-\fBCURLFORM_PTRCONTENTS\fP you must ensure that the pointer stays valid until
-you call \fIcurl_form_free\fP and \fIcurl_easy_cleanup\fP.

  source code that you write that is using libcurl for transfers. The program
  is outside libcurl and libcurl is outside of the program.
 
+ To get the more details on all options and functions described herein, please
+ refer to their respective man pages.
 
 Building
 
+ There are many different ways to build C programs. This chapter will assume a
+ unix-style build process. If you use a different build system, you can still
+ read this to get general information that may apply to your environment as
+ well.
+
   Compiling the Program
 
+    Your compiler needs to know where the libcurl headers are
+    located. Therefore you must set your compiler's include path to point to
+    the directory where you installed them. The 'curl-config'[3] tool can be
+    used to get this information:
+
+        $ curl-config --cflags
+
   Linking the Program with libcurl
 
+    When having compiled the program, you need to link your object files to
+    create a single executable. For that to succeed, you need to link with
+    libcurl and possibly also with other libraries that libcurl itself depends
+    on. Like OpenSSL librararies, but even some standard OS libraries may be
+    needed on the command line. To figure out which flags to use, once again
+    the 'curl-config' tool comes to the rescue:
+
+        $ curl-config --libs
+
   SSL or Not
 
+    libcurl can be built and customized in many ways. One of the things that
+    varies from different libraries and builds is the support for SSL-based
+    transfers, like HTTPS and FTPS. If OpenSSL was detected properly at
+    build-time, libcurl will be built with SSL support. To figure out if an
+    installed libcurl has been built with SSL support enabled, use
+    'curl-config' like this:
+
+        $ curl-config --feature
+
+    And if SSL is supported, the keyword 'SSL' will be written to stdout,
+    possibly together with a few other features that can be on and off on
+    different libcurls.
+
+
+Portable Code in a Portable World
+
+ The people behind libcurl have put a considerable effort to make libcurl work
+ on a large amount of different operating systems and environments.
+
+ You program libcurl the same way on all platforms that libcurl runs on. There
+ are only very few minor considerations that differs. If you just make sure to
+ write your code portable enough, you may very well create yourself a very
+ portable program. libcurl shouldn't stop you from that.

+Passwords
+
+ Many protocols use or even require that user name and password are provided
+ to be able to download or upload the data of your choice. libcurl offers
+ several ways to specify them.
+
+ Most protocols support that you specify the name and password in the URL
+ itself. libcurl will detect this and use them accordingly. This is written
+ like this:
+
+        protocol://user:password@example.com/path/
+
+ If you need any odd letters in your user name or password, you should enter
+ them URL encoded, as %XX where XX is a two-digit hexadecimal number.
+
+ libcurl also provides options to set various passwords. The user name and
+ password as shown embedded in the URL can instead get set with the
+ CURLOPT_USERPWD option. The argument passed to libcurl should be a char * to
+ a string in the format "user:password:". In a manner like this:
+
+        curl_easy_setopt(easyhandle, CURLOPT_USERPWD, "myname:thesecret");
+
+ Another case where name and password might be needed at times, is for those
+ users who need to athenticate themselves to a proxy they use. libcurl offers
+ another option for this, the CURLOPT_PROXYUSERPWD. It is used quite similar
+ to the CURLOPT_USERPWD option like this:
+
+        curl_easy_setopt(easyhandle, CURLOPT_PROXYUSERPWD, "myname:thesecret");
+ 
+ There's a long time unix "standard" way of storing ftp user names and
+ passwords, namely in the $HOME/.netrc file. The file should be made private
+ so that only the user may read it (see also the "Security Considerations"
+ chapter), as it might contain the password in plain text. libcurl has the
+ ability to use this file to figure out what set of user name and password to
+ use for a particular host. As an extension to the normal functionality,
+ libcurl also supports this file for non-FTP protocols such as HTTP. To make
+ curl use this file, use the CURLOPT_NETRC option:
+
+    curl_easy_setopt(easyhandle, CURLOPT_NETRC, TRUE);
+
+ And a very basic example of how such a .netrc file may look like:
+
+    machine myhost.mydomain.com
+    login userlogin
+    password secretword
+
+ All these examples have been cases where the password has been optional, or
+ at least you could leave it out and have libcurl attempt to do its job
+ without it. There are times when the password isn't optional, like when
+ you're using an SSL private key for secure transfers.
+
+ You can in this situation either pass a password to libcurl to use to unlock
+ the private key, or you can let libcurl prompt the user for it. If you prefer
+ to ask the user, then you can provide your own callback function that will be
+ called when libcurl wants the password. That way, you can control how the
+ question will appear to the user.
+
+ To pass the known private key password to libcurl:
+
+    curl_easy_setopt(easyhandle, CURLOPT_SSLKEYPASSWD, "keypassword");
+
+ To make a password callback:
+
+    int enter_passwd(void *ourp, const char *prompt, char *buffer, int len);
+    curl_easy_setopt(easyhandle, CURLOPT_PASSWDFUNCTION, enter_passwd);
+
+
+HTTP POSTing
+
+ We get many questions regarding how to issue HTTP POSTs with libcurl the
+ proper way. This chapter will thus include examples using both different
+ versions of HTTP POST that libcurl supports.
+
+ The first version is the simple POST, the most common version, that most HTML
+ pages using the <form> tag uses. We provide a pointer to the data and tell
+ libcurl to post it all to the remote site:
+
+    char *data="name=daniel&project=curl";
+    curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDS, data);
+    curl_easy_setopt(easyhandle, CURLOPT_URL, "http://posthere.com/");
+
+    curl_easy_perform(easyhandle); /* post away! */
+
+ Simple enough, huh? Since you set the POST options with the
+ CURLOPT_POSTFIELDS, this automaticly switches the handle to use POST in the
+ upcoming request.
+
+ Ok, so what if you want to post binary data that also requires you to set the
+ Content-Type: header of the post? Well, binary posts prevents libcurl from
+ being able to do strlen() on the data to figure out the size, so therefore we
+ must tell libcurl the size of the post data. Setting headers in libcurl
+ requests are done in a generic way, by building a list of our own headers and
+ then passing that list to libcurl.
+
+    struct curl_slist *headers=NULL;
+    headers = curl_slist_append(headers, "Content-Type: text/xml");
+
+    /* post binary data */
+    curl_easy_setopt(easyhandle, CURLOPT_POSTFIELD, binaryptr);
+
+    /* set the size of the postfields data */
+    curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDSIZE, 23);
+
+    /* pass our list of custom made headers */
+    curl_easy_setopt(easyhandle, CURLOPT_HTTPHEADER, headers);
+
+    curl_easy_perform(easyhandle); /* post away! */
+
+    curl_slist_free_all(headers); /* free the header list */
+
+ While the simple examples above cover the majority of all cases where HTTP
+ POST operations are required, they don't do multipart formposts. Multipart
+ formposts were introduced as a better way to post (possibly large) binary
+ data and was first documented in the RFC1867. They're called multipart
+ because they're built by a chain of parts, each being a single unit. Each
+ part has its own name and contents. You can in fact create and post a
+ multipart formpost with the regular libcurl POST support described above, but
+ that would require that you build a formpost yourself and provide to
+ libcurl. To make that easier, libcurl provides curl_formadd(). Using this
+ function, you add parts to the form. When you're done adding parts, you post
+ the whole form.
+
+ The following example sets two simple text parts with plain textual contents,
+ and then a file with binary contents and upload the whole thing.
+
+    struct curl_httppost *post=NULL;
+    struct curl_httppost *last=NULL;
+    curl_formadd(&post, &last,
+                 CURLFORM_COPYNAME, "name",
+                 CURLFORM_COPYCONTENTS, "daniel", CURLFORM_END);
+    curl_formadd(&post, &last,
+                 CURLFORM_COPYNAME, "project",
+                 CURLFORM_COPYCONTENTS, "curl", CURLFORM_END);
+    curl_formadd(&post, &last,
+                 CURLFORM_COPYNAME, "logotype-image",
+                 CURLFORM_FILECONTENT, "curl.png", CURLFORM_END);
+
+    /* Set the form info */
+    curl_easy_setopt(easyhandle, CURLOPT_HTTPPOST, post);
+
+    curl_easy_perform(easyhandle); /* post away! */
+
+    /* free the post data again */
+    curl_formfree(post);
+
+ Multipart formposts are chains of parts using MIME-style separators and
+ headers. It means that each one of these separate parts get a few headers set
+ that describe the individual content-type, size etc. To enable your
+ application to handicraft this formpost even more, libcurl allows you to
+ supply your own set of custom headers to such an individual form part. You
+ can of course supply headers to as many parts you like, but this little
+ example will show how you set headers to one specific part when you add that
+ to the post handle:
+
+    struct curl_slist *headers=NULL;
+    headers = curl_slist_append(headers, "Content-Type: text/xml");
+
+    curl_formadd(&post, &last,
+                 CURLFORM_COPYNAME, "logotype-image",
+                 CURLFORM_FILECONTENT, "curl.xml",
+                 CURLFORM_CONTENTHEADER, headers,
+                 CURLFORM_END);
+
+    curl_easy_perform(easyhandle); /* post away! */
+
+    curl_formfree(post); /* free post */
+    curl_slist_free_all(post); /* free custom header list */
+
+ Since all options on an easyhandle are "sticky", they remain the same until
+ changed even if you do call curl_easy_perform(), you may need to tell curl to
+ go back to a plain GET request if you intend to do such a one as your next
+ request. You force an easyhandle to back to GET by using the CURLOPT_HTTPGET
+ option:
+
+    curl_easy_setopt(easyhandle, CURLOPT_HTTPGET, TRUE);
+
+ Just setting CURLOPT_POSTFIELDS to "" or NULL will *not* stop libcurl from
+ doing a POST. It will just make it POST without any data to send!
+
+
+Showing Progress
+
+ For historical and traditional reasons, libcurl has a built-in progress meter
+ that can be switched on and then makes it presents a progress meter in your
+ terminal.
+
+ Switch on the progress meter by, oddly enough, set CURLOPT_NOPROGRESS to
+ FALSE. This option is set to TRUE by default.
+
+ For most applications however, the built-in progress meter is useless and
+ what instead is interesting is the ability to specify a progress
+ callback. The function pointer you pass to libcurl will then be called on
+ irregular intervals with information about the current transfer.
+
+ Set the progress callback by using CURLOPT_PROGRESSFUNCTION. And pass a
+ pointer to a function that matches this prototype:
+
+        int progress_callback(void *clientp,
+                              double dltotal,
+                              double dlnow,
+                              double ultotal,
+                              double ulnow);
+
+ If any of the input arguments is unknown, a 0 will be passed. The first
+ argument, the 'clientp' is the pointer you pass to libcurl with
+ CURLOPT_PROGRESSDATA. libcurl won't touch it.
+
+
+libcurl with C++
+
+ There's basicly only one thing to keep in mind when using C++ instead of C
+ when interfacing libcurl:
+
+    "The Callbacks Must Be Plain C"
+
+ So if you want a write callback set in libcurl, you should put it within
+ 'extern'. Similar to this:
+
+     extern "C" {
+       size_t write_data(void *ptr, size_t size, size_t nmemb,
+                         void *ourpointer)
+       {
+         /* do what you want with the data */
+       }
+    }
+
+ This will of course effectively turn the callback code into C. There won't be
+ any "this" pointer available etc.
+
+
+Proxies
+
+ What "proxy" means according to Merriam-Webster: "a person authorized to act
+ for another" but also "the agency, function, or office of a deputy who acts
+ as a substitute for another".
+
+ Proxies are exceedingly common these days. Companies often only offer
+ internet access to employees through their HTTP proxies. Network clients or
+ user-agents ask the proxy for docuements, the proxy does the actual request
+ and then it returns them.
+
+ libcurl has full support for HTTP proxies, so when a given URL is wanted,
+ libcurl will ask the proxy for it instead of trying to connect to the actual
+ host identified in the URL.
+
+ The fact that the proxy is a HTTP proxy puts certain restrictions on what can
+ actually happen. A requested URL that might not be a HTTP URL will be still
+ be passed to the HTTP proxy to deliver back to libcurl. This happens
+ transparantly, and an application may not need to know. I say "may", because
+ at times it is very important to understand that all operations over a HTTP
+ proxy is using the HTTP protocol. For example, you can't invoke your own
+ custom FTP commands or even proper FTP directory listings.
+
+  Proxy Options
+
+    To tell libcurl to use a proxy at a given port number:
+
+       curl_easy_setopt(easyhandle, CURLOPT_PROXY, "proxy-host.com:8080");
+
+    Some proxies require user authentication before allowing a request, and
+    you pass that information similar to this:
+
+       curl_easy_setopt(easyhandle, CURLOPT_PROXYUSERPWD, "user:password");
+
+    If you want to, you can specify the host name only in the CURLOPT_PROXY
+    option, and set the port number separately with CURLOPT_PROXYPORT.
+
+  Environment Variables
+
+    libcurl automaticly checks and uses a set of environment variables to know
+    what proxies to use for certain protocols. The names of the variables are
+    following an ancient de facto standard and are built up as
+    "[protocol]_proxy" (note the lower casing). Which makes the variable
+    'http_proxy' checked for a name of a proxy to use when the input URL is
+    HTTP. Following the same rule, the variable named 'ftp_proxy' is checked
+    for FTP URLs. Again, the proxies are always HTTP proxies, the different
+    names of the variables simply allows different HTTP proxies to be used.
+
+    The proxy environment variable contents should be in the format
+    "[protocol://]machine[:port]". Where the protocol:// part is simply
+    ignored if present (so http://proxy and bluerk://proxy will do the same)
+    and the optional port number specifies on which port the proxy operates on
+    the host. If not specified, the internal default port number will be used
+    and that is most likely *not* the one you would like it to be.
+
+    There are two special environment variables. 'all_proxy' is what sets
+    proxy for any URL in case the protocol specific variable wasn't set, and
+    'no_proxy' defines a list of hosts that should not use a proxy even though
+    a variable may say so. If 'no_proxy' is a plain asterisk ("*") it matches
+    all hosts.
+
+  SSL and Proxies
+
+    SSL is for secure point-to-point connections. This involves strong
+    encryption and similar things, which effectivly makes it impossible for a
+    proxy to operate as a "man in between" which the proxy's task is, as
+    previously discussed. Instead, the only way to have SSL work over a HTTP
+    proxy is to ask the proxy to tunnel trough everything without being able
+    to check or fiddle with the traffic.
+
+    Opening an SSL connection over a HTTP proxy is therefor a matter of asking
+    the proxy for a straight connection to the target host on a specified
+    port. This is made with the HTTP request CONNECT. ("please mr proxy,
+    connect me to that remote host").
+
+    Because of the nature of this operation, where the proxy has no idea what
+    kind of data that is passed in and out through this tunnel, this breaks
+    some of the very few advantages that come from using a proxy, such as
+    caching.  Many organizations prevent this kind of tunneling to other
+    destination port numbers than 443 (which is the default HTTPS port
+    number).
+
+  Tunneling Through Proxy
+
+    As explained above, tunneling is required for SSL to work and often even
+    restricted to the operation intended for SSL; HTTPS.
+
+    This is however not the only time proxy-tunneling might offer benefits to
+    you or your application.
+
+    As tunneling opens a direct connection from your application to the remote
+    machine, it suddenly also re-introduces the ability to do non-HTTP
+    operations over a HTTP proxy. You can in fact use things such as FTP
+    upload or FTP custom commands this way.
+
+    Again, this is often prevented by the adminstrators of proxies and is
+    rarely allowed.
+
+    Tell libcurl to use proxy tunneling like this:
+
+       curl_easy_setopt(easyhandle, CURLOPT_HTTPPROXYTUNNEL, TRUE);
+
+    In fact, there might even be times when you want to do plain HTTP
+    operations using a tunnel like this, as it then enables you to operate on
+    the remote server instead of asking the proxy to do so. libcurl will not
+    stand in the way for such innovative actions either!
+
+  Proxy Auto-Config
+
+    Netscape first came up with this. It is basicly a web page (usually using
+    a .pac extension) with a javascript that when executed by the browser with
+    the requested URL as input, returns information to the browser on how to
+    connect to the URL. The returned information might be "DIRECT" (which
+    means no proxy should be used), "PROXY host:port" (to tell the browser
+    where the proxy for this particular URL is) or "SOCKS host:port" (to
+    direct the brower to a SOCKS proxy).
+
+    libcurl has no means to interpret or evaluate javascript and thus it
+    doesn't support this. If you get yourself in a position where you face
+    this nasty invention, the following advice have been mentioned and used in
+    the past:
+
+    - Depending on the javascript complexity, write up a script that
+      translates it to another language and execute that.
+
+    - Read the javascript code and rewrite the same logic in another language.
+
+    - Implement a javascript interpreted, people have successfully used the
+      Mozilla javascript engine in the past.
+
+    - Ask your admins to stop this, for a static proxy setup or similar.
+
+
+Persistancy Is The Way to Happiness
+
+ Re-cycling the same easy handle several times when doing multiple requests is
+ the way to go.
+
+ After each single curl_easy_perform() operation, libcurl will keep the
+ connection alive and open. A subsequent request using the same easy handle to
+ the same host might just be able to use the already open connection! This
+ reduces network impact a lot.
+
+ Even if the connection is dropped, all connections involving SSL to the same
+ host again, will benefit from libcurl's session ID cache that drasticly
+ reduces re-connection time.
+
+ FTP connections that are kept alive saves a lot of time, as the command-
+ response roundtrips are skipped, and also you don't risk getting blocked
+ without permission to login again like on many FTP servers only allowing N
+ persons to be logged in at the same time.
+
+ libcurl caches DNS name resolving results, to make lookups of a previously
+ looked up name a lot faster.
+
+ Other interesting details that improve performance for subsequent requests
+ may also be added in the future.
+
+ Each easy handle will attempt to keep the last few connections alive for a
+ while in case they are to be used again. You can set the size of this "cache"
+ with the CURLOPT_MAXCONNECTS option. Default is 5. It is very seldom any
+ point in changing this value, and if you think of changing this it is often
+ just a matter of thinking again.
+
+ When the connection cache gets filled, libcurl must close an existing
+ connection in order to get room for the new one. To know which connection to
+ close, libcurl uses a "close policy" that you can affect with the
+ CURLOPT_CLOSEPOLICY option. There's only two polices implemented as of this
+ writing (libcurl 7.9.4) and they are:
+
+  CURLCLOSEPOLICY_LEAST_RECENTLY_USED simply close the one that hasn't been
+  used for the longest time. This is the default behavior.
+
+  CURLCLOSEPOLICY_OLDEST closes the oldest connection, the one that was
+  createst the longest time ago.
+
+ There are, or at least were, plans to support a close policy that would call
+ a user-specified callback to let the user be able to decide which connection
+ to dump when this is necessary and therefor is the CURLOPT_CLOSEFUNCTION an
+ existing option still today. Nothing ever uses this though and this will not
+ be used within the forseeable future either.
+
+ To force your upcoming request to not use an already existing connection (it
+ will even close one first if there happens to be one alive to the same host
+ you're about to operate on), you can do that by setting CURLOPT_FRESH_CONNECT
+ to TRUE. In a similar spirit, you can also forbid the upcoming request to be
+ "lying" around and possibly get re-used after the request by setting
+ CURLOPT_FORBID_REUSE to TRUE.
+
+
+Customizing Operations
+
+ There is an ongoing development today where more and more protocols are built
+ upon HTTP for transport. This has obvious benefits as HTTP is a tested and
+ reliable protocol that is widely deployed and have excellent proxy-support.
+
+ When you use one of these protocols, and even when doing other kinds of
+ programming you may need to change the traditional HTTP (or FTP or...)
+ manners. You may need to change words, headers or various data.
+
+ libcurl is your friend here too.
+
+ If just changing the actual HTTP request keyword is what you want, like when
+ GET, HEAD or POST is not good enough for you, CURLOPT_CUSTOMREQUEST is there
+ for you. It is very simple to use:
+
+    curl_easy_setopt(easyhandle, CURLOPT_CUSTOMREQUEST, "MYOWNRUQUEST");
+
+ When using the custom request, you change the request keyword of the actual
+ request you are performing. Thus, by default you make GET request but you can
+ also make a POST operation (as described before) and then replace the POST
+ keyword if you want to. You're the boss.
+
+ HTTP-like protocols pass a series of headers to the server when doing the
+ request, and you're free to pass any amount of extra headers that you think
+ fit. Adding headers are this easy:
+
+    struct curl_slist *headers=NULL; /* init to NULL is important */
+
+    headers = curl_slist_append(headers, "Hey-server-hey: how are you?");
+    headers = curl_slist_append(headers, "X-silly-content: yes");
+
+    /* pass our list of custom made headers */
+    curl_easy_setopt(easyhandle, CURLOPT_HTTPHEADER, headers);
+
+    curl_easy_perform(easyhandle); /* transfer http */
+
+    curl_slist_free_all(headers); /* free the header list */
+
+ ... and if you think some of the internally generated headers, such as
+ User-Agent:, Accept: or Host: don't contain the data you want them to
+ contain, you can replace them by simply setting them too:
+
+    headers = curl_slist_append(headers, "User-Agent: 007");
+    headers = curl_slist_append(headers, "Host: munged.host.line");
+
+ If you replace an existing header with one with no contents, you will prevent
+ the header from being sent. Like if you want to completely prevent the
+ "Accept:" header to be sent, you can disable it with code similar to this:
+
+    headers = curl_slist_append(headers, "Accept:");
+
+ Both replacing and cancelling internal headers should be done with careful
+ consideration and you should be aware that you may violate the HTTP protocol
+ when doing so.
+
+ There's only one aspect left in the HTTP requests that we haven't yet
+ mentioned how to modify: the version field. All HTTP requests includes the
+ version number to tell the server which version we support. libcurl speak
+ HTTP 1.1 by default. Some very old servers don't like getting 1.1-requests
+ and when dealing with stubborn old things like that, you can tell libcurl to
+ use 1.0 instead by doing something like this:
+
+    curl_easy_setopt(easyhandle, CURLOPT_HTTP_VERSION, CURLHTTP_VERSION_1_0);
+
+ Not all protocols are HTTP-like, and thus the above may not help you when you
+ want to make for example your FTP transfers to behave differently.
+
+ Sending custom commands to a FTP server means that you need to send the
+ comands exactly as the FTP server expects them (RFC959 is a good guide here),
+ and you can only use commands that work on the control-connection alone. All
+ kinds of commands that requires data interchange and thus needs a
+ data-connection must be left to libcurl's own judgement. Also be aware that
+ libcurl will do its very best to change directory to the target directory
+ before doing any transfer, so if you change directory (with CWD or similar)
+ you might confuse libcurl and then it might not attempt to transfer the file
+ in the correct remote directory.
+
+ A little example that deletes a given file before an operation:
+
+    headers = curl_slist_append(headers, "DELE file-to-remove");
+
+    /* pass the list of custom commands to the handle */
+    curl_easy_setopt(easyhandle, CURLOPT_QUOTE, headers);
+
+    curl_easy_perform(easyhandle); /* transfer ftp data! */
+
+    curl_slist_free_all(headers); /* free the header list */
+
+ If you would instead want this operation (or chain of operations) to happen
+ _after_ the data transfer took place the option to curl_easy_setopt() would
+ instead be called CURLOPT_POSTQUOTE and used the exact same way.
+
+ The custom FTP command will be issued to the server in the same order they
+ are added to the list, and if a command gets an error code returned back from
+ the server, no more commands will be issued and libcurl will bail out with an
+ error code (CURLE_FTP_QUOTE_ERROR). Note that if you use CURLOPT_QUOTE to
+ send commands before a transfer, no transfer will actually take place when a
+ quote command has failed.
+
+ If you set the CURLOPT_HEADER to true, you will tell libcurl to get
+ information about the target file and output "headers" about it. The headers
+ will be in "HTTP-style", looking like they do in HTTP.
+
+ The option to enable headers or to run custom FTP commands may be useful to
+ combine with CURLOPT_NOBODY. If this option is set, no actual file content
+ transfer will be performed.
+
+
+Cookies Without Chocolate Chips
+
+ In the HTTP sense, a cookie is a name with an associated value. A server
+ sends the name and value to the client, and expects it to get sent back on
+ every subsequent request to the server that matches the particular conditions
+ set. The conditions include that the domain name and path match and that the
+ cookie hasn't become too old.
+
+ In real-world cases, servers send new cookies to replace existing one to
+ update them. Server use cookies to "track" users and to keep "sessions".
+
+ Cookies are sent from server to clients with the header Set-Cookie: and
+ they're sent from clients to servers with the Cookie: header.
+
+ To just send whatever cookie you want to a server, you can use CURLOPT_COOKIE
+ to set a cookie string like this:
+
+    curl_easy_setopt(easyhandle, CURLOPT_COOKIE, "name1=var1; name2=var2;");
+
+ In many cases, that is not enough. You might want to dynamicly save whatever
+ cookies the remote server passes to you, and make sure those cookies are then
+ use accordingly on later requests.
+
+ One way to do this, is to save all headers you receive in a plain file and
+ when you make a request, you tell libcurl to read the previous headers to
+ figure out which cookies to use. Set header file to read cookies from with
+ CURLOPT_COOKIEFILE.
+
+ The CURLOPT_COOKIEFILE option also automaticly enables the cookie parser in
+ libcurl. Until the cookie parser is enabled, libcurl will not parse or
+ understand incoming cookies and they will just be ignored. However, when the
+ parser is enabled the cookies will be understood and the cookies will be kept
+ in memory and used properly in subsequent requests when the same handle is
+ used. Many times this is enough, and you may not have to save the cookies to
+ disk at all. Note that the file you specify to CURLOPT_COOKIEFILE doesn't
+ have to exist to enable the parser, so a common way to just enable the parser
+ and not read able might be to use a file name you know doesn't exist.
+
+ If you rather use existing cookies that you've previously received with your
+ Netscape or Mozilla browsers, you can make libcurl use that cookie file as
+ input. The CURLOPT_COOKIEFILE is used for that too, as libcurl will
+ automaticly find out what kind of file it is and act accordingly.
+
+ The perhaps most advanced cookie operation libcurl offers, is saving the
+ entire internal cookie state back into a Netscape/Mozilla formatted cookie
+ file. We call that the cookie-jar. When you set a file name with
+ CURLOPT_COOKIEJAR, that file name will be created and all received cookies
+ will be stored in it when curl_easy_cleanup() is called. This enabled cookies
+ to get passed on properly between multiple handles without any information
+ getting lost.
+
+
+FTP Peculiarities We Need
+
+ FTP transfers use a second TCP/IP connection for the data transfer. This is
+ usually a fact you can forget and ignore but at times this fact will come
+ back to haunt you. libcurl offers several different ways to custom how the
+ second connection is being made.
+
+ libcurl can either connect to the server a second time or tell the server to
+ connect back to it. The first option is the default and it is also what works
+ best for all the people behind firewalls, NATs or IP-masquarading setups.
+ libcurl then tells the server to open up a new port and wait for a second
+ connection. This is by default attempted with EPSV first, and if that doesn't
+ work it tries PASV instead. (EPSV is an extension to the original FTP spec
+ and does not exist nor work on all FTP servers.)
+
+ You can prevent libcurl from first trying the EPSV command by setting
+ CURLOPT_FTP_USE_EPSV to FALSE.
+
+ In some cases, you will prefer to have the server connect back to you for the
+ second connection. This might be when the server is perhaps behind a firewall
+ or something and only allows connections on a single port. libcurl then
+ informs the remote server which IP address and port number to connect to.
+ This is made with the CURLOPT_FTPPORT option. If you set it to "-", libcurl
+ will use your system's "default IP address". If you want to use a particular
+ IP, you can set the full IP address, a host name to resolve to an IP address
+ or even a local network interface name that libcurl will get the IP address
+ from.

+
+Headers Equal Fun
+
+ Some protocols provide "headers", meta-data separated from the normal
+ data. These headers are by default not included in the normal data stream,
+ but you can make them appear in the data stream by setting CURLOPT_HEADER to
+ TRUE.
+
+ What might be even more useful, is libcurl's ability to separate the headers
+ from the data and thus make the callbacks differ. You can for example set a
+ different pointer to pass to the ordinary write callback by setting
+ CURLOPT_WRITEHEADER.
+
+ Or, you can set an entirely separate function to receive the headers, by
+ using CURLOPT_HEADERFUNCTION.
+
+ The headers are passed to the callback function one by one, and you can
+ depend on that fact. It makes it easier for you to add custom header parsers
+ etc.
+
+ "Headers" for FTP transfers equal all the FTP server responses. They aren't
+ actually true headers, but in this case we pretend they are! ;-)

+
+
+Security Considerations
+
+ libcurl is in itself not insecure. If used the right way, you can use libcurl
+ to transfer data pretty safely.
+
+ There are of course many things to consider that may loosen up this
+ situation:
+
+  Command Lines
+
+    If you use a command line tool (such as curl) that uses libcurl, and you
+    give option to the tool on the command line those options can very likely
+    get read by other users of your system when they use 'ps' or other tools
+    to list currently running processes.
+
+    To avoid this problem, never feed sensitive things to programs using
+    command line options.
+
+  .netrc
+
+    .netrc is a pretty handy file/feature that allows you to login quickly and
+    automaticly to frequently visited sites. The file contains passwords in
+    clear text and is a real security risk. In some cases, your .netrc is also
+    stored in a home directory that is NFS mounted or used on another network
+    based file system, so the clear text password will fly through your
+    network every time anyone reads that file!
+
+    To avoid this problem, don't use .netrc files and never store passwords in
+    plain text anywhere.
+
+  Clear Text Passwords
+
+    Many of the protocols libcurl supports send name and password unencrypted
+    as clear text (HTTP Basic authentication, FTP, TELNET etc). It is very
+    easy for anyone on your network or a network nearby yours, to just fire up
+    a network analyzer tool and evesdrop on your passwords. Don't let the fact
+    that HTTP uses base64 encoded passwords fool you. They may not look
+    readable at a first glance, but they very easily "deciphered" by anyone
+    within seconds.
+
+    To avoid this problem, use protocols that don't let snoopers see your
+    password: HTTPS, FTPS and FTP-kerberos are a few examples. HTTP Digest
+    authentication allows this too, but isn't supported by libcurl as of this
+    writing.
+
+  Showing What You Do
+
+    On a related issue, be aware that even in situations like when you have
+    problems with libcurl and ask somone for help, everything you reveal in
+    order to get best possible help might also impose certain security related
+    risks. Host names, user names, paths, operating system specifics etc (not
+    to mention passwords of course) may in fact be used by intruders to gain
+    additional information of a potential target.
+
+    To avoid this problem, you must of course use your common sense. Often,
+    you can just edit out the senstive data or just rearch/replace your true
+    information with faked data.

+.SH NAME
+curl_formadd - add a section to a multipart/formdata HTTP POST
+.SH SYNOPSIS
+.B #include <curl/curl.h>
+.sp
+.BI "CURLFORMcode curl_formadd(struct HttpPost ** " firstitem,
+.BI "struct HttpPost ** " lastitem, " ...);"
+.ad
+.SH DESCRIPTION
+curl_formadd() is used to append sections when building a multipart/formdata
+HTTP POST (sometimes refered to as rfc1867-style posts). Append one section at
+a time until you've added all the sections you want included and then you pass
+the \fIfirstitem\fP pointer as parameter to \fBCURLOPT_HTTPPOST\fP.
+\fIlastitem\fP is set after each call and on repeated invokes it should be
+left as set to allow repeated invokes to find the end of the list faster.
+
+After the \fIlastitem\fP pointer follow the real arguments.
+
+The pointers \fI*firstitem\fP and \fI*lastitem\fP should both be pointing to
+NULL in the first call to this function. All list-data will be allocated by
+the function itself. You must call \fIcurl_formfree\fP after the form post has
+been done to free the resources again.
+
+First, there are some basics you need to understand about multipart/formdata
+posts. Each part consists of at least a NAME and a CONTENTS part. If the part
+is made for file upload, there are also a stored CONTENT-TYPE and a
+FILENAME. Below here, we'll discuss on what options you use to set these
+properties in the parts you want to add to your post.
+.SH OPTIONS
+.B CURLFORM_COPYNAME
+followed by string is used to set the name of this part. libcurl copies the
+given data, so your application doesn't need to keep it around after this
+function call. If the name isn't zero terminated properly, or if you'd like it
+to contain zero bytes, you need to set the length of the name with
+\fBCURLFORM_NAMELENGTH\fP.
+
+.B CURLFORM_PTRNAME
+followed by a string is used for the name of this part. libcurl will use the
+pointer and refer to the data in your application, you must make sure it
+remains until curl no longer needs it. If the name isn't zero terminated
+properly, or if you'd like it to contain zero bytes, you need to set the
+length of the name with \fBCURLFORM_NAMELENGTH\fP.
+
+.B CURLFORM_COPYCONTENTS
+followed by a string is used for the contents of this part, the actual data to
+send away. libcurl copies the given data, so your application doesn't need to
+keep it around after this function call. If the data isn't zero terminated
+properly, or if you'd like it to contain zero bytes, you need to set the
+length of the name with \fBCURLFORM_CONTENTSLENGTH\fP.
+
+.B CURLFORM_PTRCONTENTS
+followed by a string is used for the contents of this part, the actual data to
+send away. libcurl will use the pointer and refer to the data in your
+application, you must make sure it remains until curl no longer needs it. If
+the data isn't zero terminated properly, or if you'd like it to contain zero
+bytes, you need to set the length of the name with
+\fBCURLFORM_CONTENTSLENGTH\fP.
+
+.B CURLFORM_FILECONTENT
+followed by a file name, makes that file read and the contents will be used in
+as data in this part.
+
+.B CURLFORM_FILE
+followed by a file name, makes this part a file upload part. It sets the file
+name field to the actual file name used here, it gets the contents of the file
+and passes as data and sets the content-type if the given file match one of
+the new internally known file extension.  For \fBCURLFORM_FILE\fP the user may
+send one or more files in one part by providing multiple \fBCURLFORM_FILE\fP
+arguments each followed by the filename (and each CURLFORM_FILE is allowed to
+have a CURLFORM_CONTENTTYPE).
+
+.B CURLFORM_CONTENTTYPE
+followed by a pointer to a string with a content-type will make curl use this
+given content-type for this file upload part, possibly instead of an
+internally chosen one.
+
+.B CURLFORM_FILENAME
+followed by a pointer to a string to a name, will make libcurl use the given
+name in the file upload part, intead of the actual file name given to
+\fICURLFORM_FILE\fP.
+
+.B BCURLFORM_BUFFER
+followed by a string, tells libcurl that a buffer is to be used to upload data
+instead of using a file. The given string is used as the value of the file
+name field in the content header.
+
+.B CURLFORM_BUFFERPTR
+followed by a pointer to a data area, tells libcurl the address of the buffer
+containing data to upload (as indicated with \fICURLFORM_BUFFER\fP). The
+buffer containing this data must not be freed until after curl_easy_cleanup is
+called.
+
+.B CURLFORM_BUFFERLENGTH
+followed by a long with the size of the \fICURLFORM_BUFFERPTR\fP data area,
+tells libcurl the length of the buffer to upload.
+
+.B CURLFORM_ARRAY
+Another possibility to send options to curl_formadd() is the
+\fBCURLFORM_ARRAY\fP option, that passes a struct curl_forms array pointer as
+its value. Each curl_forms structure element has a CURLformoption and a char
+pointer. The final element in the array must be a CURLFORM_END. All available
+options can be used in an array, except the CURLFORM_ARRAY option itself!  The
+last argument in such an array must always be \fBCURLFORM_END\fP.
+
+.B CURLFORM_CONTENTHEADER
+specifies extra headers for the form POST section.  This takes a curl_slist
+prepared in the usual way using \fBcurl_slist_append\fP and appends the list
+of headers to those libcurl automatically generates. The list must exist while
+the POST occurs, if you free it before the post completes you may experience
+problems.
+
+When you've passed the HttpPost pointer to \fIcurl_easy_setopt\fP (using the
+\fICURLOPT_HTTPPOST\fP option), you must not free the list until after you've
+called \fIcurl_easy_cleanup\fP for the curl handle.
+
+See example below.

+.SH SYNOPSIS
+.B #include <curl/curl.h>
+.sp
+.BI "curl_version_info_data *curl_version_info( CURLversion "type ");"
+.ad
+.SH DESCRIPTION
+Returns a pointer to a filled in struct with information about various
+run-time features in libcurl. \fItype\fP should be set to the version of this
+functionality by the time you write your program. This way, libcurl will
+always return a proper struct that your program understands, while programs in
+the future might get an different struct. CURLVERSION_NOW will be the most
+recent one for the library you have installed:
+
+        data = curl_version_info(CURLVERSION_NOW);
+
+Applications should use this information to judge if things are possible to do
+or not, instead of using compile-time checks, as dynamic/DLL libraries can be
+changed independent of applications.
+
+The curl_version_info_data struct looks like this
+
+.nf
+typedef struct {
+  CURLversion age;          /* 0 - this kind of struct */
+  const char *version;      /* human readable string */
+  unsigned int version_num; /* numeric representation */
+  const char *host;         /* human readable string */
+  int features;             /* bitmask, see below */
+  char *ssl_version;        /* human readable string */
+  long ssl_version_num;     /* number */
+  char *libz_version;       /* human readable string */
+  const char *protocols[];  /* list of protocols */
+} curl_version_info_data;
+.fi
+
+\fIage\fP describes what kind of struct this is. It is always 0 now. In a
+future libcurl, if this struct changes, this age counter may be increased, and
+then the struct for number 1 will look different (except for this first struct
+field).
+
+\fIversion\fP is just an ascii string for the libcurl version.
+
+\fIversion_num\fP is a 6 digit hexadecimal number created like this: <2 digits
+major number> | <2 digits minor number> | <2 digits patch number>. Version
+7.9.8 is therefore returned as 0x070908.
+
+\fIhost\fP is an ascii string showing what host information that this libcurl
+was built for. As discovered by a configure script or set by the build
+environment.
+
+\fIfeatures\fP can have none, one or more bits set, and the currently defined
+bits are:
+.TP 5.5
+.B CURL_VERSION_IPV6
+supports IPv6
+.TP
+.B CURL_VERSION_KERBEROS4
+supports kerberos4 (when using FTP)
+.TP
+.B CURL_VERSION_SSL
+supports SSL (HTTPS/FTPS)
+.TP
+.B CURL_VERSION_LIBZ
+supports HTTP deflate using libz
+.PP
+\fIssl_version\fP is an ascii string for the OpenSSL version used. If libcurl
+has no SSL support, this is NULL.
+
+\fIssl_version_num\fP is the numerical OpenSSL version value as defined by the
+OpenSSL project. If libcurl has no SSL support, this is 0.
+
+\fIlibz_version\fP is an ascii string (there is no numerical version). If
+libcurl has no libz support, this is NULL.
+
+\fIprotocols\fP is a pointer to an array of char * pointers, containing the
+names protocols that libcurl supports (using lowercase letters). The protocol
+names are the same as would be used in URLs. The array is terminated by a NULL
+entry.
+
+
+.SH RETURN VALUE
+A pointer to a curl_version_info_data struct.

+.SH NAME
+error codes in libcurl
+.SH DESCRIPTION
+This man page includes most, if not all, available error codes in libcurl.
+Why they occur and possibly what you can do to fix the problem.
+.SH "CURLcode"
+Almost all "easy" interface functions return a CURLcode error code. No matter
+what, using \fICURLOPT_ERRORBUFFER\fP is a good idea as it will give you a
+human readable error string that may offer more details about the error cause
+than just the error code does.
+
+This man page is meant to describe libcurl 7.9.6 and later. Earlier versions
+might have had quirks not mentioned here.
+
+CURLcode is one of the following:
+.RS 1
+.TP 5
+.B CURLE_OK (0)
+All fine. Proceed as usual.
+.TP
+.B CURLE_UNSUPPORTED_PROTOCOL (1)
+The URL you passed to libcurl used a protocol that this libcurl does not
+support. The support might be a compile-time option that you didn't use, it
+can be a misspelled protocol string or just a protocol libcurl has no code
+for.
+.TP
+.B CURLE_FAILED_INIT (2)
+Very early initialization code failed. This is likely to be an internal error
+or problem.
+.TP
+.B CURLE_URL_MALFORMAT (3)
+The URL was not properly formatted.
+.TP
+.B CURLE_URL_MALFORMAT_USER (4)
+URL user malformatted. The user-part of the URL syntax was not correct.
+.TP
+.B CURLE_COULDNT_RESOLVE_PROXY (5)
+Couldn't resolve proxy. The given proxy host could not be resolved.
+.TP
+.B CURLE_COULDNT_RESOLVE_HOST (6)
+Couldn't resolve host. The given remote host was not resolved.
+.TP
+.B CURLE_COULDNT_CONNECT (7)
+Failed to connect() to host or proxy.
+.TP
+.B CURLE_FTP_WEIRD_SERVER_REPLY (8)
+After connecting to a FTP server, libcurl expects to get a certain reply back.
+This error code implies that it god a strange or bad reply. The given remote
+server is probably not an OK FTP server.
+.TP
+.B CURLE_FTP_ACCESS_DENIED (9)
+We were denied access when trying to login to an FTP server or when trying to
+change working directory to the one given in the URL.
+.TP
+.B CURLE_FTP_USER_PASSWORD_INCORRECT (10)
+The username and/or the password were incorrect when trying to login to an FTP
+server.
+.TP
+.B CURLE_FTP_WEIRD_PASS_REPLY (11)
+After having sent the FTP password to the server, libcurl expects a proper
+reply. This error code indicates that an unexpected code was returned.
+.TP
+.B CURLE_FTP_WEIRD_USER_REPLY (12)
+After having sent user name to the FTP server, libcurl expects a proper
+reply. This error code indicates that an unexpected code was returned.
+.TP
+.B CURLE_FTP_WEIRD_PASV_REPLY (13)
+libcurl failed to get a sensible result back from the server as a response to
+either a PASV or a EPSV command. The server is flawed.
+.TP
+.B CURLE_FTP_WEIRD_227_FORMAT (14)
+FTP servers return a 227-line as a response to a PASV command. If libcurl
+fails to parse that line, this return code is passed back.
+.TP
+.B CURLE_FTP_CANT_GET_HOST (15)
+An internal failure to lookup the host used for the new connection.
+.TP
+.B CURLE_FTP_CANT_RECONNECT (16)
+A bad return code on either PASV or EPSV was sent by the FTP server,
+preventing libcurl from being able to continue.
+.TP
+.B CURLE_FTP_COULDNT_SET_BINARY (17)
+Received an error when trying to set the transfer mode to binary.
+.TP
+.B CURLE_PARTIAL_FILE (18)
+A file transfer was shorter or larger than expected. This happens when the
+server first reports an expected transfer size, and then delivers data that
+doesn't match the previously given size.
+.TP
+.B CURLE_FTP_COULDNT_RETR_FILE (19)
+This was either a weird reply to a 'RETR' command or a zero byte transfer
+complete.
+.TP
+.B CURLE_FTP_WRITE_ERROR (20)
+After a completed file transfer, the FTP server did not respond a proper
+\"transfer successful\" code.
+.TP
+.B CURLE_FTP_QUOTE_ERROR (21)
+When sending custom "QUOTE" commands to the remote server, one of the commands
+returned an error code that was 400 or higher.
+.TP
+.B CURLE_HTTP_NOT_FOUND (22)
+This is returned if CURLOPT_FAILONERROR is set TRUE and the HTTP server
+returns an error code that is >= 400.
+.TP
+.B CURLE_WRITE_ERROR (23)
+An error occurred when writing received data to a local file, or an error was
+returned to libcurl from a write callback.
+.TP
+.B CURLE_MALFORMAT_USER (24)
+Malformat user. User name badly specified. *Not currently used*
+.TP
+.B CURLE_FTP_COULDNT_STOR_FILE (25)
+FTP couldn't STOR file. The server denied the STOR operation. The error buffer
+usually contains the server's explanation to this.
+.TP
+.B CURLE_READ_ERROR (26)
+There was a problem reading a local file or an error returned by the read
+callback.
+.TP
+.B CURLE_OUT_OF_MEMORY (27)
+Out of memory. A memory allocation request failed. This is serious badness and
+things are severly screwed up if this ever occur.
+.TP
+.B CURLE_OPERATION_TIMEOUTED (28)
+Operation timeout. The specified time-out period was reached according to the
+conditions.
+.TP
+.B CURLE_FTP_COULDNT_SET_ASCII (29)
+libcurl failed to set ASCII transfer type (TYPE A).
+.TP
+.B CURLE_FTP_PORT_FAILED (30)
+The FTP PORT command returned error. This mostly happen when you haven't
+specified a good enough address for libcurl to use. See \fICURLOPT_FTPPORT\fP.
+.TP
+.B CURLE_FTP_COULDNT_USE_REST (31)
+The FTP REST command returned error. This should never happen if the server is
+sane.
+.TP
+.B CURLE_FTP_COULDNT_GET_SIZE (32)
+The FTP SIZE command returned errror. SIZE is not a kosher FTP command, it is
+an extension and not all servers support it. This is not a surprising error.
+.TP
+.B CURLE_HTTP_RANGE_ERROR (33)
+The HTTP server does not support or accept range requests.
+.TP
+.B CURLE_HTTP_POST_ERROR (34)
+This is an odd error that mainly occurs due to internal confusion.
+.TP
+.B CURLE_SSL_CONNECT_ERROR (35)
+A problem occured somewhere in the SSL/TLS handshake. You really want the
+error buffer and read the message there as it pinpoints the problem slightly
+more. Could be certificates (file formats, paths, permissions), passwords, and
+others.
+.TP
+.B CURLE_FTP_BAD_DOWNLOAD_RESUME (36)
+Attempting FTP resume beyond file size.
+.TP
+.B CURLE_FILE_COULDNT_READ_FILE (37)
+A file given with FILE:// couldn't be opened. Most likely because the file
+path doesn't identify an existing file. Did you check file permissions?
+.TP
+.B CURLE_LDAP_CANNOT_BIND (38)
+LDAP cannot bind. LDAP bind operation failed.
+.TP
+.B CURLE_LDAP_SEARCH_FAILED (39)
+LDAP search failed.
+.TP
+.B CURLE_LIBRARY_NOT_FOUND (40)
+Library not found. The LDAP library was not found.
+.TP
+.B CURLE_FUNCTION_NOT_FOUND (41)
+Function not found. A required LDAP function was not found.
+.TP
+.B CURLE_ABORTED_BY_CALLBACK (42)
+Aborted by callback. A callback returned "abort" to libcurl.
+.TP
+.B CURLE_BAD_FUNCTION_ARGUMENT (43)
+Internal error. A function was called with a bad parameter.
+.TP
+.B CURLE_BAD_CALLING_ORDER (44)
+Internal error. A function was called in a bad order.
+.TP
+.B CURLE_HTTP_PORT_FAILED (45)
+Interface error. A specified outgoing interface could not be used. Set which
+interface to use for outgoing connections' source IP address with
+CURLOPT_INTERFACE.
+.TP
+.B CURLE_BAD_PASSWORD_ENTERED (46)
+Bad password entered. An error was signaled when the password was
+entered. This can also be the result of a "bad password" returned from a
+specified password callback.
+.TP
+.B CURLE_TOO_MANY_REDIRECTS (47)
+Too many redirects. When following redirects, libcurl hit the maximum amount.
+Set your limit with CURLOPT_MAXREDIRS.
+.TP
+.B CURLE_UNKNOWN_TELNET_OPTION (48)
+An option set with CURLOPT_TELNETOPTIONS was not recognized/known. Refer to
+the appropriate documentation.
+.TP
+.B CURLE_TELNET_OPTION_SYNTAX (49)
+A telnet option string was Illegally formatted.
+.TP
+.B CURLE_OBSOLETE (50)
+This is not an error. This used to be another error code in an old libcurl
+version and is currently unused.
+.TP
+.B CURLE_SSL_PEER_CERTIFICATE (51)
+The remote server's SSL certificate was deemed not OK.
+.TP
+.B CURLE_GOT_NOTHING (52)
+Nothing was returned from the server, and under the circumstances, getting
+nothing is considered an error.
+.TP
+.B CURLE_SSL_ENGINE_NOTFOUND (53)
+The specified crypto engine wasn't found.
+.TP
+.B CURLE_SSL_ENGINE_SETFAILED (54)
+Failed setting the selected SSL crypto engine as default!
+.TP
+.B CURLE_SEND_ERROR (55)
+Failed sending network data.
+.TP
+.B CURLE_RECV_ERROR (56)
+Failure with receiving network data.

+.SH NAME
+libcurl-multi \- how to use the multi interface
+.SH DESCRIPTION
+This is an overview on how to use the libcurl multi interface in your C
+programs. There are specific man pages for each function mentioned in
+here. There's also the libcurl-the-guide document for a complete tutorial to
+programming with libcurl and the \fIlibcurl(3)\fP man page for an overview of
+the libcurl easy interface.
+
+All functions in the multi interface are prefixed with curl_multi.
+.SH "PLEASE NOTICE"
+The multi interface is a rather new member of the libcurl family. It has not
+yet been very widely used. It may still be a few more bugs lurking in there
+than we are used to. That said, it might also just work in every aspect you
+try it. Please report all bugs and oddities you see.
+.SH "OBJECTIVES"
+The multi interface introduces several new abilities that the easy interface
+refuses to offer. They are mainly:
+
+1. Enable a "pull" interface. The application that uses libcurl decides where
+and when to ask libcurl to get/send data.
+
+2. Enable multiple simultaneous transfers in the same thread without making it
+complicated for the application.
+
+3. Enable the application to select() on its own file descriptors and curl's
+file descriptors simultaneous easily.
+.SH "ONE MULTI HANDLE MANY EASY HANDLES"
+To use the multi interface, you must first create a 'multi handle' with
+\fIcurl_multi_init\fP. This handle is then used as input to all further
+curl_multi_* functions.
+
+Each single transfer is built up with an easy handle. You must create them,
+and setup the appropriate options for each easy handle, as outlined in the
+\fIlibcurl(3)\fP man page, using \fIcurl_easy_setopt(3)\fP.
+
+When the easy handle is setup for a transfer, then instead of using
+\fIcurl_easy_perform\fP (as when using the easy interface for transfers), you
+should instead add the easy handle to the multi handle using
+\fIcurl_easy_add_handl\fP. The multi handle is sometimes referred to as a
+\'multi stack\' because of the fact that it may hold a large amount of easy
+handles.
+
+Should you change your mind, the easy handle is again removed from the multi
+stack using \fIcurl_multi_remove_handle\fP. Once removed from the multi
+handle, you can again use other easy interface functions like
+\fIcurl_easy_perform\fP on the handle or whatever you think is necessary.
+
+Adding the easy handle to the multi handle does not start the transfer.
+Remember that one of the main ideas with this interface is to let your
+application drive. You drive the transfers by invoking
+\fIcurl_multi_perform\fP. libcurl will then transfer data if there is anything
+available to transfer. It'll use the callbacks and everything else you have
+setup in the individual easy handles. It'll transfer data on all current
+transfers in the multi stack that are ready to transfer anything. It may be
+all, it may be none.
+
+Your application can acquire knowledge from libcurl when it would like to get
+invoked to transfer data, so that you don't have to busy-loop and call that
+\fIcurl_multi_perform\fP like crazy. \fIcurl_multi_fdset\fP offers an
+interface using which you can extract fd_sets from libcurl to use in select()
+or poll() calls in order to get to know when the transfers in the multi stack
+might need attention. This also makes it very easy for your program to wait
+for input on your own private file descriptors at the same time or perhaps
+timeout every now and then, should you want that.
+
+A little note here about the return codes from the multi functions, and
+especially the \fIcurl_multi_perform\fP: if you receive
+\fICURLM_CALL_MULTI_PERFORM\fP, this basicly means that you should call
+\fIcurlm_call_multi_perform\fP again, before you select() on more actions. You
+don't have to do it immediately, but the return code means that libcurl may
+have more data available to return or that there may be more data to send off
+before it is "satisfied".
+
+\fIcurl_multi_perform\fP stores the number of still running transfers in one
+of its input arguments, and by reading that you can figure out when all the
+transfers in the multi handles are done. 'done' does not mean successful. One
+or more of the transfers may have failed. Tracking when this number changes,
+you know when one or more transfers are done.
+
+To get information about completed transfers, to figure out success or not and
+similar, \fIcurl_multi_info_read\fP should be called. It can return a message
+about a current or previous transfer. Repeated invokes of the function get
+more messages until the message queue is empty. The information you receive
+there includes an easy handle pointer which you may use to identify which easy
+handle the information regards.
+
+When all transfers in the multi stack are done, cleanup the multi handle with
+\fIcurl_multi_cleanup\fP. Be careful and please note that you \fBMUST\fP
+invoke separate \fIcurl_easy_cleanup\fP calls on every single easy handle to
+clean them up properly.
+
+If you want to re-use an easy handle that was added to the multi handle for
+transfer, you must first remove it from the multi stack and then re-add it
+again (possbily after having altered some options at your own choice).
