Retrieving the caught signal within a handler
Is there a way to retrieve the signal within the signal handler? I would like to know the signal that I caught. Thanks, Joel -- http://wagerlabs.com/

Thanks Bulat! This is what I ended up doing before you posted. Sometimes just the mere fact of asking makes you come up with a solution. I use #haskell for that alot :-). On Dec 6, 2005, at 4:17 PM, Bulat Ziganshin wrote:

just pass signal number to the handler you installs :)
installHandler sigPIPE Ignore Nothing flip mapM_ [sigINT, sigHUP, sigABRT, sigTERM] $ \sig -> do installHandler sig handler Nothing where handler = Catch $ exitWith (ExitFailure 1)
On a related note, it would be nice if we could get at the information in the siginfo_t structure which can be read about in sigaction(2). John -- John Meacham - ⑆repetae.net⑆john⑈
