NAME

       SSL_SESSION_get_id, SSL_SESSION_set1_id - get and set the SSL session ID

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);

DESCRIPTION

       SSL_SESSION_get_id() returns a pointer to the internal session id value for the session s.
       The length of the id in bytes is stored in *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 ssl SSL/TLS session to sid of length
       sid_len.

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 SSL_MAX_SSL_SESSION_ID_LENGTH.
