Is that documented somewhere? The man pages don't mention it. <http://developer.apple.com/mac/library/qa/qa2005/qa1419.html> just says it must be a multiple of 4096 bytes.

The only documentation I found was the source code, but I haven’t really looked. :-)

You are aware that the ucontext stuff is deprecated on OS X, aren’t you?

What replaces them? What about signal handlers installed via sigaction that get passed a ucontext_t? Is that deprecated too?

Sorry, I don’t know. The ucontext.h header file just says those routines (*context) are deprecated. I would have thought that you could rely on them working until 10.7 though. To replace them, you can use regular threads or grand central dispatch (10.6 only) or something else. I don’t know exactly what you’re trying to do.
