"SfR Fresh" - the SfR Freeware/Shareware Archive 
As a special service "SfR Fresh" has tried to format the requested source page into HTML format using (guessed) C and C++ source code syntax highlighting with prefixed line numbers.
Alternatively you can here view or download the uninterpreted source code file.
That can be also achieved for any archive member file by clicking within an archive contents listing on the first character of the file(path) respectively on the according byte size field.

2 * Purpose: The C/C++ header file that defines the OSS API.
3 * Description:
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.
7 *
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
