23 .TH CURLINFO_TLS_SESSION 3 "12 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
24 .SH NAME
25 CURLINFO_TLS_SESSION \- get TLS session info
26 .SH SYNOPSIS
27 .nf
28 #include <curl/curl.h>
29
30 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_TLS_SESSION,
31 struct curl_tlssessioninfo **session);
32 .SH DESCRIPTION
33 \fBThis option has been superseded\fP by \fICURLINFO_TLS_SSL_PTR(3)\fP which
34 was added in 7.48.0. The only reason you would use this option instead is if
35 you could be using a version of libcurl earlier than 7.48.0.
36
37 This option is exactly the same as \fICURLINFO_TLS_SSL_PTR(3)\fP except in the
38 case of OpenSSL. If the session \fIbackend\fP is CURLSSLBACKEND_OPENSSL the
39 session \fIinternals\fP pointer varies depending on the option:
40
41 CURLINFO_TLS_SESSION OpenSSL session \fIinternals\fP is SSL_CTX *.
42
43 CURLINFO_TLS_SSL_PTR OpenSSL session \fIinternals\fP is SSL *.
44
45 You can obtain an SSL_CTX pointer from an SSL pointer using OpenSSL function
46 SSL_get_SSL_CTX. Therefore unless you need compatibility with older versions of
47 libcurl use \fICURLINFO_TLS_SSL_PTR(3)\fP. Refer to that document for more
48 information.
49 .SH PROTOCOLS
50 All TLS-based
51 .SH EXAMPLE
52 .nf
53 CURL *curl = curl_easy_init();
54 if(curl) {
55 CURLcode res;
56 struct curl_tlssessioninfo *tls;
57 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
58 res = curl_easy_perform(curl);
59 curl_easy_getinfo(curl, CURLINFO_TLS_SESSION, &tls);
60 curl_easy_cleanup(curl);
61 }
62 .fi
63 .SH AVAILABILITY
64 Added in 7.34.0, and supported OpenSSL, GnuTLS, NSS and gskit only up until
65 7.48.0 was released.
66 .SH RETURN VALUE
67 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
