pcntl_sigtimedwait — Waits for signals, with a timeout

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

set: 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.
nanoseconds: Timeout in nanoseconds.

Return Values

On success, pcntl_sigtimedwait() returns a signal number.
