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.
