Iterating Glib's GMainLoop with NSRunLoop

[Hugo Melder]

Hey,

I am currently using GStreamer as part of a project, and started using 
Objective-C for non-GStreamer components of the application.
The loads of macros and boilerplate were just to much…

However, I am currently stuck at integrating (At the moment only iterating) the 
Glib mainloop.
The Glib provides the GMainLoop, which is similar to NSRunLoop and can be 
manually iterated:

loop->is_running = TRUE;
while (loop->is_running)
  {
    g_main_context_iteration (context, TRUE);
  }

The second argument of g_main_context_iteration indicates whether the iteration 
should block.

I thought about using an NSTimer with a high polling frequency, but that seems 
like a hack to me. Is there a better way (maybe even a GNUstep specific one) to 
install a hook into the runloop? The RunLoop Observer APIs does not seem to be 
available with GNUstep’s NSRunLoop implementation.

Writing a GMainLoop compatible “class”, and bridging to the NSRunLoop by 
translating all Glib Events would be a more complex solution.

Any ideas or tips are welcome :)

Best Regards,
