Implemented by: @mozilla.org/process/util;1. To create an instance, use:

               .createInstance(Components.interfaces.nsIProcess2);

Method overview

void runAsync([array, size_is(count)] in string args, in unsigned long count, [optional] in nsIObserver observer, [optional] in boolean holdWeak);

Methods

runAsync()

Asynchronously runs the process with which the object was initialized, optionally calling an observer when the process finishes running.

void runAsync(
  [array, size_is(count)] in string args,
  in unsigned long count,
  in nsIObserver observer, Optional
  in boolean holdWeak Optional
);

Parameters

args

An array of arguments to pass into the process, using the native character set. This array must have count entries.

count

The number of arguments passed in the args array.

observer Optional

An observer that will be notified when the process exits. The observer will receive this nsIProcess2 instance as the subject and "process-finished" or "process-failed" as the topic. The observer will be notified on the main thread.

holdWeak Optional

If true, a weak reference is used to hold the observer.
