Circular buffers form a very important part of the Netcruzer Library. They are used for many of the modules contained in the library, and provide a consistent way for exchanging data between modules. In it's simplest form it is a "first in, first out" BYTE buffer. It provides the basic functions for reading and writing data from and to the buffer. But also contains many additional, more advanced functions.

For details on Circular Buffers, see the nz_CircularBuffer.h Documentation.
