gnutls_dh_get_group(3)             gnutls             gnutls_dh_get_group(3)

NAME         top

       gnutls_dh_get_group - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

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

ARGUMENTS         top

       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         top

       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         top

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