> # NAME

> cgGetFirstTechniqueAnnotation - get the first annotation of a technique

> # SYNOPSIS

>       #include <Cg/cg.h>

>       CGannotation cgGetFirstTechniqueAnnotation( CGtechnique tech );

> # PARAMETERS

> tech

>   The technique from which to retrieve the annotation.

> # RETURN VALUES

> Returns the first annotation in the given technique.

> Returns NULL if the technique has no annotations or an error occurs.

> # DESCRIPTION

> The annotations associated with a technique can be retrieved using cgGetFirstTechniqueAnnotation. The remainder of the technique's annotations can be discovered by iterating through the parameters, calling cgGetNextAnnotation to get to the next one.

> # EXAMPLES

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

> # ERRORS

> CG_INVALID_TECHNIQUE_HANDLE_ERROR is generated if tech is not a valid technique.

> # HISTORY

> cgGetFirstTechniqueAnnotation was introduced in Cg 1.4.
