Returns the credentials of the foreign process connected to this
socket, if any (e.g. it is only supported for %G_SOCKET_FAMILY_UNIX
sockets).
If this operation isn't supported on the OS, the method fails with
the %G_IO_ERROR_NOT_SUPPORTED error. On Linux this is implemented
by reading the %SO_PEERCRED option on the underlying socket.
Other ways to obtain credentials from a foreign peer includes the
#GUnixCredentialsMessage type and
g_unix_connection_send_credentials() /
g_unix_connection_receive_credentials() functions.
Return: %NULL if @error is set, otherwise a #GCredentials object
that must be freed with g_object_unref().
