>       CGannotation ann = cgGetFirstProgramAnnotation( program );
>       while( ann )
>       {
>          /* do something with ann */
>          ann = cgGetNextAnnotation( ann );
>       }

> # ERRORS

> CG_INVALID_PROGRAM_HANDLE_ERROR is generated if program is not a valid program handle.

> # HISTORY

> cgGetFirstProgramAnnotation was introduced in Cg 1.4.
