Description

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.

Parameters

Array of signals to wait for.

siginfo

The siginfo is set to an array containing informations about the signal. See pcntl_sigwaitinfo().

seconds

Timeout in seconds.
