.TH CURLINFO_TLS_SESSION 3 "May 31, 2017" "libcurl 7.73.0" "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\fBThis option has been superseded\fP by \fICURLINFO_TLS_SSL_PTR(3)\fP which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
|
|
.nf
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode res;
|
|
struct curl_tlssessioninfo *tls;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
|
|
res = curl_easy_perform(curl);
|
|
curl_easy_getinfo(curl, CURLINFO_TLS_SESSION, &tls);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
.fi
|
|
.SH AVAILABILITY
|
|
Added in 7.34.0, and supported OpenSSL, GnuTLS, NSS and gskit only up until
|
|
7.48.0 was released.
|
|
.SH RETURN VALUE
|
|
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
