pcntl_sigtimedwait — Waits for signals, with a timeout
$set
[, array &$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.
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.
On success, pcntl_sigtimedwait() returns a signal number.
