DESCRIPTION

25       This function will  return  the  group  parameters  used  in  the  last
26       Diffie-Hellman key exchange with the peer.  These are the prime and the
27       generator used.  This function should be used for  both  anonymous  and
28       ephemeral  Diffie-Hellman.   The  output  parameters must be freed with
29       gnutls_free().
30
31       Note, that the prime and generator are exported as  non-negative  inte‐
32       gers and may include a leading zero byte.
33

RETURNS

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