Detailed Description

Instant Messaging API class By creating this class the user automatically connects to the Symbian server but to do something reasonable the IM interface has to be created using this class.

The following order of calling the methods is one possibility to use this class: 1. NewL() - instantiate the object 2. RegisterObserverL() - register the observer methods 3. LoginL() - connect to the protocol stack and login to remote IM server 4. CreateImClientL() - get the IM interface

All the error codes are returned using the leave mechanism.
