Re^6: $SIG{ALRM} and windows vista?

On Windows Vista, your code doesn't do anything useful. Specifically, your code fails to display the message "Enter your password:" and then wait for the user to enter their password. Instead, your code does nothing, then prints out "Enter your password: you timed out."

In an effort to get "Enter your password: " to display immediately, I tried setting the output buffer to flush output immediately by setting $| = 1, but that didn't change the result.

On Windows Vista, your code doesn't do anything useful. It does! It demonstrates that alarm works, when the operation, (sleep in this case), doesn't involve IO. Ie. The `sleep 10;` was interupted by the `alarm 5`. And that was the only reason I posted it. For a solution to your problem that works, see Term::ReadKey Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

Instead, your code does nothing, then prints out "Enter your password: you timed out." As it should. His code demonstrates that `alarm` will interrupt `sleep` on Windows.	[reply] [d/l] [select]
