File: handle.hxx
Description:
All of the classes in the handle management layer which are common to
both the client runtime and the server runtime are in this file. The
classes used only by the server runtime live in hndlsvr.hxx. The
classes described here are independent of specific RPC protocol as
well as transport.
The class GENERIC_OBJECT is used is the root for the handle class hierarchy.
It provides dynamic type checking for all handles.
The MESSAGE_OBJECT class provides a common protocol for all of the handle
types which know to send and receive messages.
The CCONNECTION class represents a call handle on the client side.
The BINDING_HANDLE class is a binding handle as used by a client to perform
remote procedure calls.

GENERIC_OBJECT :
The GENERIC_OBJECT class serves as the base for all handles used by the

specific (magic) value which is checked whenever the handle is validated.
