SYNOPSIS

       #include <gnutls/gnutls.h>

       int gnutls_dh_get_group(gnutls_session_t session, gnutls_datum_t * raw_gen, gnutls_datum_t * raw_prime);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls session

       gnutls_datum_t * raw_gen
                   will hold the generator.

       gnutls_datum_t * raw_prime
                   will hold the prime.

DESCRIPTION

       This  function  will  return  the  group parameters used in the last Diffie-Hellman key exchange with the
       peer.  These are the prime and the generator used.  This function should be used for both  anonymous  and
       ephemeral Diffie-Hellman.  The output parameters must be freed with gnutls_free().

       Note,  that  the prime and generator are exported as non-negative integers and may include a leading zero
       byte.

RETURNS

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