   Changelog for the c-ares project
 
+* August 3 2006
+
+- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and
+  not always zero!
+
+Version 1.3.1 (June 24, 2006)
+
+* July 23, 2006
+
+- Gisle Vanem added getopt() to the ahost program. Currently accepts
+  only [-t {a|aaaa}] to specify address family in ares_gethostbyname().
+
+* June 19, 2006
+
+- (wahern) Removed "big endian" DNS section and RR data integer parser
+  macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise
+  operations in C operate on logical values. And in any event the octets are
+  already in big-endian (aka network) byte order so they're being reversed
+  (thus the source of the breakage).
+
+* June 18, 2006
+
+- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
+  from area_process.c.
+
+  TODO: Handle one last EAGAIN for a UDP socket send(2) in
+  ares__send_query().
+
+* May 10, 2006
+
+- Bram Matthys brought my attention to a libtool peculiarity where detecting
+  things such as C++ compiler actually is a bad thing and since we don't need
+  that detection I added a work-around, much inspired by a previous patch by
+  Paolo Bonzini. This also shortens the configure script quite a lot.
+
+* May 3, 2006
+
+- Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes
+  c-ares call a callback on socket state changes. A better way than the
+  ares_getsock() to get full control over the socket state.
+
+* January 9, 2006
+
+- Alexander Lazic improved the getservbyport_r() configure check.
+
+* January 6, 2006
+
+- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS
+  variable for easier controlling what it does and how it runs.
+
+* January 5, 2006
+
+- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it
+  build with newer gcc versions that no longer defines "riscos".
+
+* December 22
+
+- Daniel Stenberg added ares_getsock() that extracts the set of sockets to
+  wait for action on. Similar to ares_fds() but not restricted to using
+  select() for the waiting.
+
 * November 25
 
 - Yang Tse fixed some send() / recv() compiler warnings

+.SH NAME
+ares_getsock \- get file descriptors to wait on
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_getsock(ares_channel \fIchannel\fP, int *\fIsocks\fP, 
+.B int \fInumsocks\fP);
+.fi
+.SH DESCRIPTION
+The
+.B ares_getsock
+function retrieves the set of file descriptors which the calling
+application should wait on for reading and/or writing for the
+processing of name service queries pending on the name service channel
+identified by
+.IR channel .
+File descriptors will be set in the integer array pointed to by
+\fIsocks\fP.
+\fInumsocks\fP is the size of the given array in number of ints.
+
+This function can only return information about up to 16 sockets. If more are
+in use (however unlikely that is), they are simply not reported back.
+.SH RETURN VALUES
+\fBares_getsock\fP returns a bitmask for what actions to wait for on the
+different sockets. The ares.h header file provides these convenience macros to
+extract the information appropriately:
+
+.nf
+#define ARES_GETSOCK_MAXNUM 16 /* ares_getsock() can return info about
+                                  this many sockets */
+#define ARES_GETSOCK_READABLE(bits,num) (bits & (1<< (num)))
+#define ARES_GETSOCK_WRITABLE(bits,num) (bits & (1 << ((num) + \
+                                         ARES_GETSOCK_MAXNUM)))
+.fi
+.SH NOTES
+This function was added in c-ares 1.3.1

+ * This example code only builds as-is on Windows.
+ *
+ * Synchronising your computer clock via Internet time server usually relies
+ * on DAYTIME, TIME, or NTP protocols. These protocols provide good accurate
+ * time synchronisation but it does not work very well through a
+ * firewall/proxy. Some adjustment has to be made to the firewall/proxy for
+ * these protocols to work properly.
+ *
+ * There is an indirect method. Since most webserver provide server time in
+ * their HTTP header, therefore you could synchronise your computer clock
+ * using HTTP protocol which has no problem with firewall/proxy.
+ *
+ * For this software to work, you should take note of these items.
+ * 1. Your firewall/proxy must allow your computer to surf internet.
+ * 2. Webserver system time must in sync with the NTP time server,
+ *    or at least provide an accurate time keeping.
+ * 3. Webserver HTTP header does not provide the milliseconds units,
+ *    so there is no way to get very accurate time.
+ * 4. This software could only provide an accuracy of +- a few seconds,
+ *    as Round-Trip delay time is not taken into consideration.
+ *    Compensation of network, firewall/proxy delay cannot be simply divide
+ *    the Round-Trip delay time by half.
+ * 5. Win32 SetSystemTime() API will set your computer clock according to
+ *    GMT/UTC time. Therefore your computer timezone must be properly set.
+ * 6. Webserver data should not be cached by the proxy server. Some
+ *    webserver provide Cache-Control to prevent caching.
+ *
+ * References:
+ * http://tf.nist.gov/timefreq/service/its.htm
+ * http://tf.nist.gov/timefreq/service/firewall.htm
+ *
+ * Usage:
+ * This software will synchronise your computer clock only when you issue
+ * it with --synctime. By default, it only display the webserver's clock.

+.TH curl_easy_escape 3 "7 April 2006" "libcurl 7.15.4" "libcurl Manual"
+.SH NAME
+curl_easy_escape - URL encodes the given string
+.SH SYNOPSIS
+.B #include <curl/curl.h>
+.sp
+.BI "char *curl_easy_escape( CURL *" curl ", char *" url ", int "length " );"
+.ad
+.SH DESCRIPTION
+This function converts the given input string to an URL encoded string and
+returns that as a new allocated string. All input characters that are not a-z,
+A-Z or 0-9 are converted to their "URL escaped" version (%NN where NN is a
+two-digit hexadecimal number).
+
+If the \fBlength\fP argument is set to 0 (zero), curl_easy_escape() uses
+strlen() on the input \fBurl\fP to find out the size.
+
+You must \fIcurl_free(3)\fP the returned string when you're done with it.
+.SH AVAILABILITY
+Added in 7.15.4 and replaces the old curl_escape() function.
+.SH RETURN VALUE
+A pointer to a zero terminated string or NULL if it failed.
+.SH "SEE ALSO"
+.BR curl_easy_unescape "(3), " curl_free "(3), " RFC 2396

+.SH NAME
+curl_multi_assign \- set data to associated with an internal socket
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLMcode curl_multi_assign(CURLM *multi_handle, curl_socket_t sockfd,
+                            void *sockptr);
+.SH DESCRIPTION
+This function assigns an association in the multi handle between the given
+socket and a private pointer of the application. This is (only) useful for
+\fIcurl_multi_socket(3)\fP uses.
+
+When set, the \fIsockptr\fP pointer will be passed to all future socket
+callbacks for the specific \fIsockfd\fP socket.
+
+If the given \fIsockfd\fP isn't already in use by libcurl, this function will
+return an error.
+
+libcurl only keeps one single pointer associated with a socket, so calling
+this function several times for the same socket will make the last set pointer
+get used.
+
+The idea here being that this association (socket to private pointer) is
+something that just about every application that uses this API will need and
+then libcurl can just as well do it since it already has an internal hash
+table lookup for this.
+.SH "RETURN VALUE"
+The standard CURLMcode for multi interface error codes.
+.SH "TYPICAL USAGE"
+In a typical application you allocate a struct or at least use some kind of
+semi-dynamic data for each socket that we must wait for action on when using
+the \fIcurl_multi_socket(3)\fP approach.
+
+When our socket-callback get called by libcurl and we get to know about yet
+another socket to wait for, we can use \fIcurl_multi_assign(3)\fP to point out
+the particular data so that when we get updates about this same socket again,
+we don't have to find the struct associated with this socket by ourselves.
+.SH AVAILABILITY
+This function was added in libcurl 7.15.5, although not deemed stable yet.
