.TH CURLINFO_TLS_SESSION 3 "12 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
|
||
|
|
.SH NAME
|
||
|
|
CURLINFO_TLS_SESSION \- get TLS session info
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_TLS_SESSION,
|
||
|
|
struct curl_tlssessioninfo **session);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
\fBThis option has been superseded\fP by \fICURLINFO_TLS_SSL_PTR(3)\fP which
|
||
|
|
was added in 7.48.0. The only reason you would use this option instead is if
|
||
|
|
you could be using a version of libcurl earlier than 7.48.0.
|
||
|
|
|
||
|
|
This option is exactly the same as \fICURLINFO_TLS_SSL_PTR(3)\fP except in the
|
||
|
|
case of OpenSSL. If the session \fIbackend\fP is CURLSSLBACKEND_OPENSSL the
|
||
|
|
session \fIinternals\fP pointer varies depending on the option:
|
||
|
|
|
||
|
|
CURLINFO_TLS_SESSION OpenSSL session \fIinternals\fP is SSL_CTX *.
|
||
|
|
|
||
|
|
CURLINFO_TLS_SSL_PTR OpenSSL session \fIinternals\fP is SSL *.
|
||
|
|
|
||
|
|
You can obtain an SSL_CTX pointer from an SSL pointer using OpenSSL function
|
||
|
|
SSL_get_SSL_CTX. Therefore unless you need compatibility with older versions of
|
||
|
|
libcurl use \fICURLINFO_TLS_SSL_PTR(3)\fP. Refer to that document for more
|
||
|
|
information.
|
||
|
|
.SH PROTOCOLS
|
||
|
|
All TLS-based
|
||
|
|
.SH EXAMPLE

struct curl_tlssessioninfo *tls;
|

curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
