23 .TH CURLINFO_TLS_SESSION 3 "May 31, 2017" "libcurl 7.59.0" "curl_easy_getinfo options"
26 CURLINFO_TLS_SESSION \- get TLS session info
29 #include <curl/curl.h>
31 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_TLS_SESSION,
32 struct curl_tlssessioninfo **session);
34 \fBThis option has been superseded\fP by \fICURLINFO_TLS_SSL_PTR(3)\fP which
35 was added in 7.48.0. The only reason you would use this option instead is if
36 you could be using a version of libcurl earlier than 7.48.0.
38 This option is exactly the same as \fICURLINFO_TLS_SSL_PTR(3)\fP except in the
39 case of OpenSSL. If the session \fIbackend\fP is CURLSSLBACKEND_OPENSSL the
40 session \fIinternals\fP pointer varies depending on the option:
42 CURLINFO_TLS_SESSION OpenSSL session \fIinternals\fP is SSL_CTX *.
44 CURLINFO_TLS_SSL_PTR OpenSSL session \fIinternals\fP is SSL *.
46 You can obtain an SSL_CTX pointer from an SSL pointer using OpenSSL function
47 SSL_get_SSL_CTX. Therefore unless you need compatibility with older versions of
48 libcurl use \fICURLINFO_TLS_SSL_PTR(3)\fP. Refer to that document for more
54 CURL *curl = curl_easy_init();
57 struct curl_tlssessioninfo *tls;
58 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
59 res = curl_easy_perform(curl);
60 curl_easy_getinfo(curl, CURLINFO_TLS_SESSION, &tls);
61 curl_easy_cleanup(curl);
65 Added in 7.34.0, and supported OpenSSL, GnuTLS, NSS and gskit only up until
68 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
