opts: 19 more CURLINFO_* options made into stand-alone man pages

.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
