>     CGannotation cgCreateTechniqueAnnotation( CGtechnique tech,
>                                               const char * name,
>                                               CGtype type );

> ## Parameters

> tech
>   The technique to which the new annotation will be added.
> name
>   The name of the new annotation.
> type
>   The type of the new annotation.

> ## Return Values

> Returns the new CGannotation handle on success.

> Returns NULL if an error occurs.

> ## Description

> cgCreateTechniqueAnnotation adds a new annotation to the technique.

> ## Examples

>     /* create a float annotation named "Apple" for CGtechnique technique */
>     CGannotation ann = cgCreateTechniqueAnnotation( tech, "Apple", CG_FLOAT );

> ## Errors

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

> CG_DUPLICATE_NAME_ERROR is generated if name is already used by an annotation for this technique.

> CG_INVALID_ENUMERANT_ERROR is generated if type is not CG_INT, CG_FLOAT, CG_BOOL, or CG_STRING.

> ## History
