How do I set an alarm less than one second in Linux?
I’ve been using alarm() system calls and alert handlers in my C programs. Recently I decided to set the alarm to less than a second, so I passed it to 0.5 and found that the alarm() function accepts an unsigned integer. Is it possible to set an alarm of less than one second?
Solution
Use the ualarm(usecs, interval) method instead.
