Hello, >From the code below:
eval {
local $SIG{ALRM} = sub { die "TIMEOUT\n" };
alarm($seconds);
... code to execute with timeout here ...
alarm(0); # cancel alarm (if code ran fast)
};
alarm(0); # cancel alarm (if eval failed)
Is the second alarm(0) needed or not?
In my before experience, I used only one alarm(0) in eval { }.
Please suggest, thanks.
Jenn.
