zookeeper_dispatch

(PECL zookeeper >= 0.4.0)

zookeeper_dispatchCalls callbacks for pending operations

Beschreibung

zookeeper_dispatch(): voidvoid

The zookeeper_dispatch() function calls the callbacks passed by operations like Zookeeper::get() or Zookeeper::exists().

Achtung

Since version 0.4.0, this function must be called manually to achieve asynchronous operations. If you want that to be done automatically, you also can declare ticks at the beginning of your program.

After PHP 7.1, you can ignore this function. This extension uses EG(vm_interrupt) to implement async dispatch.

Parameter-Liste

Diese Funktion besitzt keine Parameter.

Rückgabewerte

Es wird kein Wert zurückgegeben.

Fehler/Exceptions

This method emits PHP warning when callback could not be invoked.
