You missed one G_TYPE_INVALID:
instead of this line:
dbus_g_proxy_call(dbus_g_p
roxy, GET_SERVICE_PROVIDER_NAME, NULL, G_TYPE_INVALID, G_TYPE_STRING,
&operator_name, G_TYPE_UINT, &val1, G_TYPE_UINT, &val2, G_TYPE_INT, &val3)
use this:
dbus_g_proxy_call(dbus_g_p
roxy, GET_SERVICE_PROVIDER_NAME, NULL, G_TYPE_INVALID, G_TYPE_STRING,
&operator_name, G_TYPE_UINT, &val1, G_TYPE_UINT, &val2, G_TYPE_INT, &val3,
G_TYPE_INVALID)
