NAME
       gnutls_dh_get_prime_bits - return the bits used in DH authentication
SYNOPSIS
       #include <gnutls/gnutls.h>
       int gnutls_dh_get_prime_bits(gnutls_session_t session);
ARGUMENTS
       gnutls_session_t session
                   is a gnutls session
DESCRIPTION
       This  function  will  return  the  bits  of  the prime used in the last
       Diffie-Hellman authentication with the peer.  Should be used  for  both
       anonymous  and  ephemeral Diffie-Hellman.  Note that some ciphers, like
       RSA and DSA without DHE, does not use a  Diffie-Hellman  exchange,  and
       then this function will return 0.
RETURNS
       The  Diffie-Hellman bit strength is returned, or 0 if no Diffie-Hellman
       exchange was done, or a negative error code on failure.
