Re: Main Event Loop and Thread.

[Oben Sonne <obensonne@xxxxxxxxxxxxxx>]

A similar question has been discussed earlier in this list starting with 
this post:

It will not start a new thread. It will attach a new source (a 
timeout-source) to the default main context. The default main context 
will be handled by the thread which runs a main loop for the default 
main context, for instance like this:

  GMainLoop *ml;
  ml = g_main_loop_new(NULL, FALSE); // NULL means default context
  g_main_loop_run(ml);

(In my understanding there is exactly one _default_ main context per 
process - please fix me if I am wrong..)

In the thread above, the following post may answer your question:

Hope this helps..
