Detailed Description

template<typename T>
class pp::CompletionCallbackWithOutput< T >

A CompletionCallbackWithOutput defines a completion callback that additionally stores a pointer to some output data. Some C++ wrappers take a CompletionCallbackWithOutput when the browser is returning a bit of data as part of the function call. The "output" parameter stored in the CompletionCallbackWithOutput will receive the data from the browser.

You can create this yourself, but it is most common to use with the CompletionCallbackFactory's NewCallbackWithOutput, which manages the storage for the output parameter for you and passes it as an argument to your callback function.

Note that this class doesn't actually do anything with the output data, it just stores a pointer to it. C++ wrapper objects that accept a CompletionCallbackWithOutput will retrieve this pointer and pass it to the browser as the output parameter.
