Detailed Description

Async call handler.

A pointer to IAsync is returned by asynchronous call (any method having a _Async suffix). This pointer is useful for context identification on async call return notification, but also to cancel the async call. An Async operation can be canceled using the ICHAI::CancelAsync() method.

Warning

the pointer to IAsync becomes invalid as soon the return notification call is done
