pcntl_sigtimedwait — Waits for signals, with a timeout

Description

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.

Parameters

signals

Array of signals to wait for.

info

The info is set to an array containing information about the signal. See pcntl_sigwaitinfo().

seconds

Timeout in seconds.

nanoseconds

Timeout in nanoseconds.

Return Values

pcntl_sigtimedwait() returns a signal number on success, or false on failure.
