2 * Purpose: The C/C++ header file that defines the OSS API.
4 * This header file contains all the declarations required to compile OSS
5 * programs. The latest version is always installed together with OSS
6 * use of the latest version is strongly recommended.
8 * {!notice This header file contains many obsolete definitions
9 * (for compatibility with older applications that still ned them).
10 * Do not use this file as a reference manual of OSS.
11 * Please check the OSS Programmer's guide for descriptions
12 * of the supported API details (http://manuals.opensound.com/developer).}
