This document explains a typical 'T' and 'R' class.
TAndRClasses shows a typical ‘T’ class
and a typical ‘R’ class.
The ‘T’ type is a value type, owning no external object.
The ‘R’ type is a resource type; typically this is proxy for an object owned elsewhere. In practice, the 'R' type is a handle to a resource owned and managed by the Kernel.
In this example, the ‘R’ class derives from the standard Symbian
platform handle class RTimer.

The Symbian platform build process describes how to build this application, which results in an executable called:
\epoc32\release\<target>\<urel
or udeb>\TANDRCLASSES.EXE.
Run the executable TANDRCLASSES.EXE.
Executables for the emulator targets wins and winscw can be run on your PC. Executables
for ARM targets must be copied to your target platform before being
run.
