pcntl_sigtimedwait — Waits for signals, with a timeout

Descrizione

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.
