pcntl_sigtimedwait — Waits for signals, with a timeout
pcntl_sigtimedwait( array $signals, array &$info = [], int $seconds = 0, int $nanoseconds = 0 ): int|false
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.
signalsArray of signals to wait for.
info The info is set to an array containing information about the signal. See pcntl_sigwaitinfo().
secondsTimeout in seconds.
nanosecondsTimeout in nanoseconds.
pcntl_sigtimedwait() returns a signal number on success, or false on failure.
