 REVISION HISTORY


 Description:

------------------------------------------------------------------------------
 INCLUDE DESCRIPTION

 Main header file for the Packet Video AMR Wide  Band  decoder library. The
 constants, structures, and functions defined within this file, along with
 a basic data types header file, is all that is needed to use and communicate
 with the library. The internal data structures within the library are
 purposely hidden.

 ---* Need description of the input buffering. *-------

 ---* Need an example of calling the library here *----
