Signal\wait([Signal\TERM], function (Signal\Info $info) {
    // Do something useful
}, 10);

Postpone certain signals

use Crunch\Signal;

$oldMask = Signal\block([Signal\TERM, Signal\HUP]);
// Some critical stuff
Signal\reset($oldMask);

A simple timer

use Crunch\Signal;

Signal\Timer(5);
Signal\wait([Signal\TERM, Signal\ALRM], function (Signal\Info $info) {
    // Do something useful
}, 10);

Register a signal handler. declare(ticks=x) is required.

declare(ticks=1);
use Crunch\Signal;

require __DIR__ . '/../vendor/autoload.php';


echo posix_getpid() . PHP_EOL;
Signal\register(Signal\USR1, function (Signal\Info $info) { echo "USR1!"; exit; });

while (true) {
    // very busy code
}
