* MHD_gtls_session_get_id - Returns session id.
* @session: is a #MHD_gtls_session_t structure.
* @session_id: is a pointer to space to hold the session id.
* @session_id_size: is the session id's size, or it will be set by the function.
*
* Returns the current session id. This can be used if you want to check if
* the next session you tried to resume was actually resumed.
* This is because resumed sessions have the same sessionID with the
* original session.
*
* Session id is some data set by the server, that identify the current session.
* In TLS 1.0 and SSL 3.0 session id is always less than 32 bytes.
*
* Returns zero on success.
