NAME
          DtNurbsTrimGetIndex - Get the trim indices for the given
          NURBS surface.


     SYNOPSIS
          #include <Dt.h>


          int  DtNurbsTrimGetIndex( int shapeID, int groupID, int trimID, int *count, long **indices )


     DESCRIPTION
          DtNurbsTrimGetIndex() returns the trim indicies in the NURBS
          surface, via the pointer to the variable indices. The number
          of indices in the surface is returned via the pointer to
          count. The indices are for the trimID on the surface
          indicated by 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
          DtNurbsTrimGetIndex() returns one on success and zero on
          failure.
