void gnutls_psk_set_server_credentials_function(gnutls_psk_server_credentials_t cred, gnutls_psk_server_credentials_function * func);
is a gnutls_psk_server_credentials_t structure.
is the callback function
This function can be used to set a callback to retrieve the user’s PSK credentials. The callback’s function form is: int (*callback)(gnutls_session_t, const char* username, gnutls_datum_t* key);
username contains the actual username. The key must be filled in using the gnutls_malloc().
In case the callback returned a negative number then gnutls will assume that the username does not exist.
The callback function will only be called once per handshake. The callback function should return 0 on success, while −1 indicates an error.
