| |
| 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. |
