Hi David,
I'm not really clear on what you're trying to do, here: looking at
IO::Async seems to indicate that you want your program to continue
while waiting for the timer, but your sample code would seem to pause
while the timer elapses. If you *don't* want to block for the timer,
the normal idom would be:
eval {
local $SIG{ALRM} = { # usually dies };
alarm $timeout;
# do something here until timeout
};
if ($@) { #check $@ to make sure alarm died, not something else }
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.
HTH,
