NAME

       gnutls_session_get_id - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       int   gnutls_session_get_id(gnutls_session_t   session,   void   *  session_id,  size_t  *
       session_id_size);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t type.

       void * session_id
                   is a pointer to space to hold the session id.

       size_t * session_id_size
                   initially should contain the maximum  session_id size and will be updated.

DESCRIPTION

       Returns the current session ID. This can be used if you want to check if the next  session
       you tried to resume was actually resumed.  That is because resumed sessions share the same
       session ID with the original session.

       The session ID is selected by the server, that  identify  the  current  session.   In  all
       supported TLS protocols, the session id is less than GNUTLS_MAX_SESSION_ID_SIZE.

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
