|
| + instead of attaching the event listeners directly to the <EMBED> element to
|
| + ensure that the listeners are active before the NaCl module 'load' event
|
| + fires. This also allows you to use PPB_Messaging.PostMessage() (in C) or
|
| + pp::Instance.PostMessage() (in C++) from within the initialization code in
|
| + your NaCl module.
