Purpose

Allows -a thread or process to identify an object which is owned or managed by another -thread or process. Handles allow a client to access, or refer to, Kernel objects.

-
Architectural -relationships

All handles are instances of classes derived from RHandleBase. -Interactions between the holder of a handle and the object which the handle -represents are mediated through the Kernel. Handles are also used in client-server -relations; the client side refers to a server side session through a handle, -anRSessionBase object.

-
Description

The -handle class, RHandleBase, encapsulates the basic behavior -common to all handles; for example, Close() to close a handle. -In particular, the class hides the handle-number which identifies the object -which the handle represents.

The class is abstract in the sense that -a RHandleBase object is never explicitly instantiated. It -is always a base class to a concrete handle class; for example, RSemaphore, RMutex, RThread etc.
