int gnutls_mac_set_priority(gnutls_session_t session, const int * list);
is a gnutls_session_t structure.
const int * list
is a 0 terminated list of gnutls_mac_algorithm_t elements.
Sets the priority on the mac algorithms supported by gnutls.
Priority is higher for elements specified before others.
After specifying the algorithms you want, you must append a 0.
Note that the priority is set on the client. The server does
not use the algorithm's priority except for disabling
algorithms that were not specified.
