This example demonstrates the how to use the circular buffer classes CCirBuf and CCirBuffer .
This example application shows how to construct and make use of circular buffers containing integers, objects of user defined classes and objects of an R class.

adds four elements until the buffer is full,
tries to adds another element to the buffer, which fails with a buffer full error message,
removes elements 1 and 2 from the buffer, leaving elements 3 and 4,
adds two new elements (5 and 6) to the buffer,
removes all elements (3, 4, 5 and 6) from the buffer.
After removing R class objects from the circular buffer, they must be closed in order to release the resource held by the R Class objects.
To build the example:
You can build the example from your IDE or the command line.
If you use an IDE, import the bld.inf file of the example into your IDE, and use the build command of the IDE.
If you use the command line, open a command prompt, and set the current directory to the source code directory of the example. You can then build the example with the SBSv1 build tools with the following commands:
abld build .
For the emulator, the example builds an executable called circularbuffer.exe in the epoc32\release\winscw\<udeb or urel>\ folder.
