> ## Name

> cgGetBoolAnnotationValues - get the values from a boolean-valued annotation

> ## Synopsis

>     #include <Cg/cg.h>

>     const CGbool * cgGetBoolAnnotationValues( CGannotation ann,
>                                               int * nvalues );

> ## Parameters

> ann
>   The annotation.
> nvalues
>   Pointer to integer where the number of returned values will be stored.

> ## Return Values

> Returns a pointer to an array of CGbool values. The number of values in the array is returned via the nvalues parameter.

> Returns NULL if no values are available. nvalues will be 0.

> ## Description

> cgGetBoolAnnotationValues allows the application to retrieve the value(s) of a boolean typed annotation.

> ## Examples

> to-be-written

> ## Errors

> CG_INVALID_ANNOTATION_HANDLE_ERROR is generated if ann is not a valid annotation.

> CG_INVALID_PARAMETER_ERROR is generated if nvalues is NULL.

> ## History

> cgGetBoolAnnotationValues was introduced in Cg 1.5.
