설명
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.
