pcntl_sigtimedwait — Waits for signals, with a timeout
$signals,&$info = [],$seconds = 0,$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.
signalsArray of signals to wait for.
info
The info is set to an array containing
information about the signal. See
pcntl_sigwaitinfo().
