- get and set the SSL session ID

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 const unsigned char *SSL_SESSION_get_id(const SSL_SESSION *s,

                                         unsigned int *len)

 int SSL_SESSION_set1_id(SSL_SESSION *s, const unsigned char *sid,

                         unsigned int sid_len);

=head1 DESCRIPTION

SSL_SESSION_get_id() returns a pointer to the internal session id value for the

session B<s>. The length of the id in bytes is stored in B<*len>. The length may

be 0. The caller should not free the returned pointer directly.

SSL_SESSION_set1_id() sets the session ID for the B<ssl> SSL/TLS session

to B<sid> of length B<sid_len>.

=head1 RETURN VALUES

SSL_SESSION_get_id() returns a pointer to the session id value.

SSL_SESSION_set1_id() returns 1 for success and 0 for failure, for example

if the supplied session ID length exceeds B<SSL_MAX_SSL_SESSION_ID_LENGTH>.
