[pclasses-devel] Fwd: you ever work with C signals?

[stephan b. <st...@s1...>]

Hiya! i just corrected a missing var in SimpleApp and came across this 
code:

	#ifdef SIGTERM
	::signal(SIGTERM, &signalHandler);
	#endif
	#ifdef SIGQUIT
	::signal(SIGQUIT, &signalHandler);
	#endif
	#ifdef SIGINT
	::signal(SIGINT, &signalHandler);
	#endif

Coincidentally... please take a look at the attached class. It greatly 
simplifies/safe-ifies this type of manipulation, and is EASY to use.
If it's okay with you i'll put it in the tree (or you can). Where should 
it go (in App or System?).

Last night i came up with a handy little class for embedding C signal
handlers in different scopes. It wraps up a signal handler for a given
scope and then restores it to the original when it goes out of scope.
This allowed me to easily solve most/all of the ctrl-c problems in
teeny because i can more easily block of one specific block for signal
handling without having to care about existing handlers. It doesn't
inherently have any longjmp support, but i'm not yet sure if a) it
needs it and b) that can be generically handled in a class like this.

Attached - a standalone file suitable for inclusion in your projects...
