That's a nice idea as long as you don't let the calling function return. As far as I know, gcc nested functions don't in any way "hold onto" the outer state, so there'll be a pile of segfaults waiting for you if the outer function has returned - like returning a pointer to an automatic variable. Is there a reason you're trying to write high-level code in C? Give Python or Pike a shot - both have GTK bindings and are way WAY easier to write code in. Believe me, I've written plenty of C code (including GUI handling), and life is just so much better when memory management isn't part of your daily keyboarding regimen. ChrisA PS.
