SetWindowsHookEx for Mac OS X?

Question

Windows hooks allows you to poke inside other processes and sometimes alter their behaviors.

Is there such thing for Mac OS X?

Thanks!

Answer 1

What are you trying to accomplish, specifically? Can you explain why you want the Mac OS X equivalent of SetWindowsHookEx()? (Short answer: there isn't one. Medium answer: just about everything you can do with SetWindowsHookEx() on Windows can be done on Mac OS X in some other, more OO way.)
