NAME
    cgGetDependentStateAssignmentParameter - get one of the parameters that
    a state assignment's value depends on

SYNOPSIS
      #include <Cg/cg.h>

      CGparameter cgGetDependentStateAssignmentParameter( CGstateassignment sa,
                                                          int index );

PARAMETERS
    sa      The state assignment handle.

    index   The index of the parameter to return.

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

    Returns NULL if an error occurs.

DESCRIPTION
    State assignments in CgFX files may include references to one or more
    effect parameters on the right hand side of the state assignment that
    are used for computing the state assignment's value.
    cgGetDependentStateAssignmentParameter returns one of these parameters,
    as indicated by the given index. the
    cgGetNumDependentStateAssignmentParameters 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.

EXAMPLES
    *to-be-written*

ERRORS
    CG_INVALID_STATE_ASSIGNMENT_HANDLE_ERROR is generated if sa is not a
    valid state assignment.

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

HISTORY
    cgGetDependentStateAssignmentParameter was introduced in Cg 1.4.
