19
20See L<SSL_CTX_set_session_id_context(3)> for further details on session ID
21contexts.
22
23SSL_SESSION_get0_id_context() returns the ID context associated with
24the SSL/TLS session B<s>. The length of the ID context is written to
25B<*len> if B<len> is not NULL.
26
27The value returned is a pointer to an object maintained within B<s> and
28should not be released.
29
30SSL_SESSION_set1_id_context() takes a copy of the provided ID context given in
31B<sid_ctx> and associates it with the session B<s>. The length of the ID context
32is given by B<sid_ctx_len> which must not exceed SSL_MAX_SID_CTX_LENGTH bytes.
