pcntl_sigtimedwaitWaits for signals, with a timeout


int pcntl_sigtimedwait ( array $set [, array &$siginfo [, int $seconds = 0 [, int $nanoseconds = 0 ]]] )

The pcntl_sigtimedwait() function operates in exactly the same way as pcntl_sigwaitinfo() except that it takes two additional parameters, seconds and nanoseconds, which enable an upper bound to be placed on the time for which the script is suspended.
