GLibSourcedestroy

Removes a source from its GMainContext, if any, and mark it as destroyed. The source cannot be subsequently added to another context. It is safe to call this on sources which have already been removed from their context.

This does not unref the GSource: if you still hold a reference, use g_source_unref() to drop it.

This function is safe to call from any thread, regardless of which thread the GMainContext is running in.

If the source is currently attached to a GMainContext, destroying it will effectively unset the callback similar to calling g_source_set_callback(). This can mean, that the data’s GDestroyNotify gets called right away.
