@ -92,150 +92,43 @@ See \fICURLINFO_CONTENT_TYPE(3)\fP
.IP CURLINFO_PRIVATE
See \fICURLINFO_PRIVATE(3)\fP
.IP CURLINFO_HTTPAUTH_AVAIL
Pass a pointer to a long to receive a bitmask indicating the authentication
method(s) available. The meaning of the bits is explained in the
\fICURLOPT_HTTPAUTH(3)\fP option for \fIcurl_easy_setopt(3)\fP. (Added in
7.10.8)
See \fICURLINFO_HTTPAUTH_AVAIL(3)\fP
.IP CURLINFO_PROXYAUTH_AVAIL
Pass a pointer to a long to receive a bitmask indicating the authentication
method(s) available for your proxy authentication. (Added in 7.10.8)
See \fICURLINFO_PROXYAUTH_AVAIL(3)\fP
.IP CURLINFO_OS_ERRNO
Pass a pointer to a long to receive the errno variable from a connect failure.
Note that the value is only set on failure, it is not reset upon a
successful operation. (Added in 7.12.2)
See \fICURLINFO_OS_ERRNO(3)\fP
.IP CURLINFO_NUM_CONNECTS
Pass a pointer to a long to receive how many new connections libcurl had to
create to achieve the previous transfer (only the successful connects are
counted). Combined with \fICURLINFO_REDIRECT_COUNT\fP you are able to know
how many times libcurl successfully reused existing connection(s) or not. See
the Connection Options of \fIcurl_easy_setopt(3)\fP to see how libcurl tries
to make persistent connections to save time. (Added in 7.12.3)
See \fICURLINFO_NUM_CONNECTS(3)\fP
.IP CURLINFO_PRIMARY_IP
Pass a pointer to a char pointer to receive the pointer to a zero-terminated
string holding the IP address of the most recent connection done with this
\fBcurl\fP handle. This string may be IPv6 if that's enabled. Note that you
get a pointer to a memory area that will be re-used at next request so you
need to copy the string if you want to keep the information. (Added in 7.19.0)
See \fICURLINFO_PRIMARY_IP(3)\fP
.IP CURLINFO_PRIMARY_PORT
Pass a pointer to a long to receive the destination port of the most recent
connection done with this \fBcurl\fP handle. (Added in 7.21.0)
See \fICURLINFO_PRIMARY_PORT(3)\fP
.IP CURLINFO_LOCAL_IP
Pass a pointer to a char pointer to receive the pointer to a zero-terminated
string holding the local (source) IP address of the most recent connection done
with this \fBcurl\fP handle. This string may be IPv6 if that's enabled. The
same restrictions apply as to \fICURLINFO_PRIMARY_IP\fP. (Added in 7.21.0)
See \fICURLINFO_LOCAL_IP(3)\fP
.IP CURLINFO_LOCAL_PORT
Pass a pointer to a long to receive the local (source) port of the most recent
connection done with this \fBcurl\fP handle. (Added in 7.21.0)
See \fICURLINFO_LOCAL_PORT(3)\fP
.IP CURLINFO_COOKIELIST
Pass a pointer to a 'struct curl_slist *' to receive a linked-list of all
cookies cURL knows (expired ones, too). Don't forget to
\fIcurl_slist_free_all(3)\fP the list after it has been used. If there are no
cookies (cookies for the handle have not been enabled or simply none have been
received) 'struct curl_slist *' will be set to point to NULL.
Since 7.43.0 cookies that were imported in the Set-Cookie format without a
domain name are not exported by this option.
(Added in 7.14.1)
See \fICURLINFO_COOKIELIST(3)\fP
.IP CURLINFO_LASTSOCKET
Pass a pointer to a long to receive the last socket used by this curl
session. If the socket is no longer valid, -1 is returned. When you finish
working with the socket, you must call curl_easy_cleanup() as usual and let
libcurl close the socket and cleanup other resources associated with the
handle. This is typically used in combination with
\fICURLOPT_CONNECT_ONLY(3)\fP. (Added in 7.15.2)
NOTE: this API is deprecated since it is not working on win64 where the SOCKET
type is 64 bits large while its 'long' is 32 bits. Use the
\fICURLINFO_ACTIVESOCKET\fP instead, if possible.
See \fICURLINFO_LASTSOCKET(3)\fP
.IP CURLINFO_ACTIVESOCKET
Pass a pointer to a curl_socket_t to receive the active socket used by this
curl session. If the socket is no longer valid, -1 is returned. When you
finish working with the socket, you must call curl_easy_cleanup() as usual and
let libcurl close the socket and cleanup other resources associated with the
handle. This is typically used in combination with
\fICURLOPT_CONNECT_ONLY(3)\fP.
NOTE: this is meant as a cross-platform, safe alternative to
\fICURLINFO_LASTSOCKET\fP, which does not work on win64.
See \fICURLINFO_ACTIVESOCKET(3)\fP
.IP CURLINFO_FTP_ENTRY_PATH
Pass a pointer to a char pointer to receive a pointer to a string holding the
path of the entry path. That is the initial path libcurl ended up in when
logging on to the remote FTP server. This stores a NULL as pointer if
something is wrong. (Added in 7.15.4)
Also works for SFTP since 7.21.4
See \fICURLINFO_FTP_ENTRY_PATH(3)\fP
.IP CURLINFO_CERTINFO
Pass a pointer to a 'struct curl_certinfo *' and you'll get it set to point to
struct that holds a number of linked lists with info about the certificate
chain, assuming you had \fICURLOPT_CERTINFO(3)\fP enabled when the previous
request was done. The struct reports how many certs it found and then you can
extract info for each of those certs by following the linked lists. The info
chain is provided in a series of data in the format "name:content" where the
content is for the specific named data. See also the certinfo.c example. NOTE:
this option is only available in libcurl built with OpenSSL, NSS or GSKit
support. (Added in 7.19.1)
See \fICURLINFO_CERTINFO(3)\fP
.IP CURLINFO_TLS_SESSION
Pass a pointer to a 'struct curl_tlssessioninfo *'. The pointer will be
initialized to refer to a 'struct curl_tlssessioninfo *' that will contain an
enum indicating the SSL library used for the handshake and the respective
internal TLS session structure of this underlying SSL library.
This may then be used to extract certificate information in a format
convenient for further processing, such as manual validation. NOTE: this
option may not be available for all SSL backends; unsupported SSL backends
will return 'CURLSSLBACKEND_NONE' to indicate that they are not supported;
this does not mean that no SSL backend was used. (Added in 7.34.0)
.nf
struct curl_tlssessioninfo {
curl_sslbackend backend;
void *internals;
};
.fi
The \fIinternals\fP struct member will point to a TLS library specific pointer
with the following underlying types:
.RS
.IP OpenSSL
SSL_CTX *
.IP GnuTLS
gnutls_session_t
.IP NSS
PRFileDesc *
.IP gskit
gsk_handle
.RE
See \fICURLINFO_TLS_SESSION(3)\fP
.IP CURLINFO_CONDITION_UNMET
Pass a pointer to a long to receive the number 1 if the condition provided in
the previous request didn't match (see \fICURLOPT_TIMECONDITION(3)\fP). Alas,
if this returns a 1 you know that the reason you didn't get data in return is
because it didn't fulfill the condition. The long ths argument points to will
get a zero stored if the condition instead was met. (Added in 7.19.4)
See \fICURLINFO_CONDITION_UNMET(3)\fP
.IP CURLINFO_RTSP_SESSION_ID
Pass a pointer to a char pointer to receive a pointer to a string holding the
most recent RTSP Session ID.
Applications wishing to resume an RTSP session on another connection should
retrieve this info before closing the active connection.
See \fICURLINFO_RTSP_SESSION_ID(3)\fP
.IP CURLINFO_RTSP_CLIENT_CSEQ
Pass a pointer to a long to receive the next CSeq that will be used by the
application.
See \fICURLINFO_RTSP_CLIENT_CSEQ(3)\fP
.IP CURLINFO_RTSP_SERVER_CSEQ
Pass a pointer to a long to receive the next server CSeq that will be expected
by the application.
\fI(NOTE: listening for server initiated requests is currently
unimplemented).\fP
Applications wishing to resume an RTSP session on another connection should
retrieve this info before closing the active connection.
See \fICURLINFO_RTSP_SERVER_CSEQ(3)\fP
.IP CURLINFO_RTSP_CSEQ_RECV
Pass a pointer to a long to receive the most recently received CSeq from the
server. If your application encounters a \fICURLE_RTSP_CSEQ_ERROR\fP then you
may wish to troubleshoot and/or fix the CSeq mismatch by peeking at this value.
See \fICURLINFO_RTSP_CSEQ_RECV(3)\fP

.SH DESCRIPTION
Pass a pointer to a char pointer to receive the pointer to a zero-terminated
string holding the IP address of the most recent connection done with this
\fBcurl\fP handle. This string may be IPv6 when that is enabled. Note that you
get a pointer to a memory area that will be re-used at next request so you
need to copy the string if you want to keep the information.
The \fBip\fP pointer will be NULL or pointing to private memory you MUST NOT
free - it gets freed when you call \fIcurl_easy_cleanup(3)\fP on the
corresponding CURL handle.

.SH DESCRIPTION
Pass a pointer to a 'struct curl_tlssessioninfo *'. The pointer will be
initialized to refer to a 'struct curl_tlssessioninfo *' that will contain an
enum indicating the SSL library used for the handshake and the respective
internal TLS session structure of this underlying SSL library.
This may then be used to extract certificate information in a format
convenient for further processing, such as manual validation. NOTE: this
option may not be available for all SSL backends; unsupported SSL backends
will return 'CURLSSLBACKEND_NONE' to indicate that they are not supported;
this does not mean that no SSL backend was used.
.nf
