NAME
          DtNurbsGetNumCtrlPoints - Get the number of control points
          for the given NURBS surface.


     SYNOPSIS
          #include <Dt.h>


          int  DtNurbsGetNumCtrlPoints( int shapeID, int groupID, int *uNum, int *vNum )


     DESCRIPTION
          DtNurbsGetNumCtrlPoints() returns the number of control
          points in the u and v directions, via the pointers to uNum
          and vNum. The control points are for the the shape shapeID
          and group groupID.


     IMPLEMENTATION
          The AliasAPI implementation of Dt does not support any
          NURBS geometry.  No NURBS geometry will be returned by this
          function.


     DIAGNOSTICS
          DtNurbsGetNumCtrlPoints() returns one on success and zero on
          failure.
