Cg Core Runtime API          cgGetDependentAnnotationParameter(3)



NAME
     cgGetDependentAnnotationParameter - get one of the
     parameters that an annotation's value depends on

SYNOPSIS
       #include 

       CGparameter cgGetDependentAnnotationParameter( CGannotation ann,
                                                      int index );


PARAMETERS
     ann     The annotation handle.

     index   The index of the parameter to return.

RETURN VALUES
     Returns a handle to the selected dependent annotation on
     success.

     Returns NUL if an error occurs.

DESCRIPTION
     Annotations in CgFX files may include references to one or
     more effect parameters on the right hand side of the
     annotation that are used for computing the annotation's
     value.  cgGetDependentAnnotationParameter returns one of
     these parameters, as indicated by the given index.
     cgGetNumDependentAnnotationParameters can be used to
     determine the total number of such parameters.

     This information can be useful for applications that wish to
     cache the values of annotations so that they can determine
     which annotations may change as the result of changing a
     particular parameter's value.

EXAMPLES
     to-be-written

ERORS
     CGINVALIDANOTATIONHANDLEROR is generated if ann is
     not a valid annotation.

     CGOUTOFARAYBOUNDSEROR is generated if index is less
     than zero or greater than or equal to the number of
     dependent parameters, as returned by
     cgGetNumDependentAnnotationParameters.

HISTORY
     cgGetDependentAnnotationParameter was introduced in Cg 1.4.
