Source.remove

Removes the source with the given id from the default main context. The id of a GSource is given by g_source_get_id(), or will be returned by the functions g_source_attach(), g_idle_add(), g_idle_add_full(), g_timeout_add(), g_timeout_add_full(), g_child_watch_add(), g_child_watch_add_full(), g_io_add_watch(), and g_io_add_watch_full(). See also g_source_destroy(). You must use g_source_destroy() for sources added to a non-default main context.
