Either way, you should be able to use the built-in functions to
accomplish your task. See the docs for sleep(), alarm(), and select()
for more info.
Sorry for the bad explanation of my problem.
Yes my program has to continue while waiting for the timeout.
You code example doesn't work for me because my program is an entire
Catalyst application which I dont think is a good idea to put into an
eval block.
You may not need an eval block:
perldoc -f alarm
[ SNIP ]
If you want to use "alarm" to time out a system call you
need to use an "eval"/"die" pair. You can’t rely on the
alarm causing the system call to fail with $! set to "EINTR"
because Perl sets up signal handlers to restart system calls
on some systems. Using "eval"/"die" always works, modulo
the caveats given in "Signals" in perlipc.
And besides, an eval with a block is compiled at the same time as the
rest of your program and doesn't have the run-time overhead of a string
eval.
