20SSL_SESSION_get_id() returns a pointer to the internal session id value for the
21session B<s>. The length of the id in bytes is stored in B<*len>. The length may
22be 0. The caller should not free the returned pointer directly.

24SSL_SESSION_set1_id() sets the session ID for the B<ssl> SSL/TLS session
25to B<sid> of length B<sid_len>.
