Overview
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 gnutls_datum_t* username, gnutls_datum_t* key, gnutls_psk_key_flags *flags);
This callback function has the same semantics as that of gnutls_psk_set_server_credentials_function2(), but it returns flags associated with the key. The callback may import external PSK using the method described in RFC 9258 by using gnutls_psk_format_imported_identity().
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.
