NAME
          DtNurbsTrimGetCount - Get the number of trim vertices in the
          NURBS surface.


     SYNOPSIS
          #include <Dt.h>


          int  DtNurbsTrimGetCount( int shapeID, int groupID, int *count);


     DESCRIPTION
          DtNurbsTrimGetCount() returns the number of trim vertices
          via the pointer to the count parameter.  The trim vertices
          are assiciated with the surface 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
          DtNurbsTrimGetCount() returns one on success and zero on
          failure.
