GTK+ modules to the rescue

GTK+ has this very simple module API: gtk_module_init() is called to initialize the module.

GTK+ modules are a very easy and effective way to add functionality to GTK+ that requires features from components way higher in the stack. They can also be quite handy as debugging tools.

Say, we want to measure it takes for an application to finish starting up. I've seen many people do this in one of two ways:

Add an idle callback to the application code and recompile
Using a stopwatch

I wrote a small gtk module (accompanying Makefile) to do just that. The whole thing is only 50 lines. You can run it with:

IDLE_ACTION="time" for it to print time it takes from gtk init to the idle callback
IDLE_ACTION="quit" for it to call gtk_main_quit() in the idle callback
IDLE_ACTION="kill" for it to send SIGINT to the process in the idle callback

No rights claimed. Essentially public domain. Updated the code to reflect that.
