=head1 NAME
SSL_SESSION_get0_id_context,
SSL_SESSION_set1_id_context
- get and set the SSL ID context associated with a session
=head1 SYNOPSIS
#include <openssl/ssl.h>
const unsigned char *SSL_SESSION_get0_id_context(const SSL_SESSION *s,
unsigned int *len)
int SSL_SESSION_set1_id_context(SSL_SESSION *s, const unsigned char *sid_ctx,
unsigned int sid_ctx_len);
=head1 DESCRIPTION
See L<SSL_CTX_set_session_id_context(3)> for further details on session ID
contexts.
SSL_SESSION_get0_id_context() returns the ID context associated with
the SSL/TLS session B<s>. The length of the ID context is written to
B<*len> if B<len> is not NULL.
The value returned is a pointer to an object maintained within B<s> and
should not be released.
SSL_SESSION_set1_id_context() takes a copy of the provided ID context given in
B<sid_ctx> and associates it with the session B<s>. The length of the ID context
is given by B<sid_ctx_len> which must not exceed SSL_MAX_SID_CTX_LENGTH bytes.
=head1 RETURN VALUES
SSL_SESSION_set1_id_context() returns 1 on success or 0 on error.
=head1 SEE ALSO
