pcntl_sigtimedwait

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

説明

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.

戻り値

On success, pcntl_sigtimedwait() returns a signal number.
