NAME

     CURLINFO_TLS_SESSION - get TLS session info

SYNOPSIS

     #include <curl/curl.h>

     CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_TLS_SESSION,
                                struct curl_tlssessioninfo **session);

DESCRIPTION

     This option has been superseded  by  CURLINFO_TLS_SSL_PTR(3)
     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  CURLINFO_TLS_SSL_PTR(3)
     except  in  the  case  of OpenSSL. If the session backend is
     CURLSSLBACKEND_OPENSSL the session internals pointer  varies
     depending on the option:

     CURLINFO_TLS_SESSION OpenSSL session internals is SSL_CTX *.

     CURLINFO_TLS_SSL_PTR OpenSSL session internals 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
     CURLINFO_TLS_SSL_PTR(3).  Refer  to  that  document for more
     information.

PROTOCOLS

     All TLS-based

EXAMPLE

     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);
     }

AVAILABILITY

     Added in 7.34.0, and  supported  OpenSSL,  GnuTLS,  NSS  and
     gskit only up until 7.48.0 was released.

RETURN VALUE

     Returns  CURLE_OK  if   the   option   is   supported,   and
     CURLE_UNKNOWN_OPTION if not.
