  *  - You quit the message loop via PostQuit with should_destroy set to
  *    PP_FALSE. In this case, the system will assume the message loop will be
  *    run again later and keep your tasks.
  *
  * To do proper shutdown, call PostQuit with should_destroy = PP_TRUE. This
  * will prohibit future work from being posted, and will allow the message loop
  * to run until all pending tasks are run.
  *
  * If you post a callback to a message loop that's been destroyed, or to an
- * invalid message loop, PostTask will return an error and will not run the
+ * invalid message loop, PostWork will return an error and will not run the
  * callback. This is true even for callbacks with the "required" flag set,
  * since the system may not even know what thread to issue the error callback
  * on.
  *
  * Therefore, you should check for errors from PostWork and destroy any
  * associated memory to avoid leaks. If you're using the C++
  * CompletionCallbackFactory, use the following pattern:
  *
  *   pp::CompletionCallback callback = factory_.NewOptionalCallback(...);
  *   int32_t result = message_loop.PostWork(callback);
