NAME

       gnutls_dh_get_group - API function

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.
