NAME
    cgGetDependentAnnotationParameter - returns one of the parameters that a
    annotation's value depends on.

SYNOPSIS
      #include <Cg/cg.h>

      CGparameter cgGetDependentAnnotationParameter(CGannotation ann, int index);

PARAMETERS
    ann     Specifies the annotation handle.

    index   Specifies the index of the parameter to return.

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 index given. the
    cgGetNumDependentAnnotationParameters manpage 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.

ERRORS
    CG_INVALID_ANNOTATION_HANDLE_ERROR is generated if ann does not refer to
    a valid annotation.

    CG_OUT_OF_ARRAY_BOUNDS_ERROR is generated if index is less than zero or
    greater than the number of dependent parameters, as returned by the
    cgGetNumDependentStateAssignmentParameters manpage.
