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. 33 34=head1 RETURN VALUES 35 36SSL_SESSION_set1_id_context() returns 1 on success or 0 on error. 37 38=head1 SEE ALSO 39 40L<ssl(7)>, 41L<SSL_set_session_id_context(3)> 42 43=head1 HISTORY 44 45The SSL_SESSION_get0_id_context() function was added in OpenSSL 1.1.0. 46 47=head1 COPYRIGHT 48 49Copyright 2015-2016 The OpenSSL Project Authors.
