NAME         top

       gnutls_dh_get_prime_bits - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       int gnutls_dh_get_prime_bits(gnutls_session_t session);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls session

DESCRIPTION         top

       This function will return the bits of the prime used in the last
       Diffie-Hellman key exchange with the peer.  Should be used for
       both anonymous and ephemeral Diffie-Hellman.  Note that some
       ciphers, like RSA and DSA without DHE, do not use a
       Diffie-Hellman key exchange, and then this function will return

RETURNS         top

       The Diffie-Hellman bit strength is returned, or 0 if no
       Diffie-Hellman key exchange was done, or a negative error code on
