TRequestStatus Class Reference
Detailed Description
Indicates the completion status of a request made to a service provider.
When a thread makes a request, it passes a request status as a parameter. On completion, the provider signals the requesting thread's request semaphore and stores a completion code in the request status. Typically, this is KErrNone or one of the other system-wide error codes.
This class is not intended for user derivation.
