Logging interrupt signals

neilwatson has asked for the wisdom of the Perl Monks concerning the following question:

I'm currently using Tie::Syslog to log any dies or errors as a result of incorrect user input. What about interrupts? If a user performs a ctrl-c is there a way I can catch and log that to stderr?

You want to look at `sh$ perldoc -q signal` - this shows you how to add entries to the SIG hash - e.g. `$SIG{INT} = sub { $Interrupted++; syswrite(STDERR, "ouch\n", 5); }` [download] cheers davis It's not easy to juggle a pregnant wife and a troubled child, but somehow I managed to fit in eight hours of TV a day.

Just point the `INT` signal handler at some code e.g `$SIG{INT} = sub { warn @_ };` [download] See. the `%SIG` entry in `perlvar` for more information on setting up signal handlers. HTH `_________ broquaint`	[reply] [d/l]
