I guess the problem is that as far as I can tell, there is no way to implement a "correct" bracket along with the existing POSIX signal implementation, since there's no way to find out what the current handler is, which means bracket can't install its own handler without messing up the current handler.
Hmm, I don't think I understand this. bracket is just fine as it is; it's just the signal handler which needs to raise an exception, right?
My point is that if you wanted to implement a signal-safe bracket, there is no way to do so, since the user may have implemented a signal handler already, and you can't find out what it is. -- David Roundy http://www.abridgegame.org
