NAME
	  DtLineGetTextureIndex	- Get the list of line texture
	  indices for all the line in the given	shape and group	IDs.


     SYNOPSIS
	  #include <Dt.h>


	  int  DtLineGetTextureIndex( int shapeID, int groupID,	int *count, long **indices);


     DESCRIPTION
	  DtLineGetTextureIndex() returns a list of line texture
	  indices via the pointer to the variable indices given	the
	  shape	number,	shapeID, and group number, groupID. The	total
	  number of texture indices into the texture list (the length
	  of the indices array)	is returned via	the pointer to the
	  count	parameter.  Each line in the indices array is
	  separated by an index	DtEND_OF_FACE (-1). The	number of
	  indices return via the pointer to count includes the
	  DtEND_OF_FACE	separators.  For example, if the first group
	  (groupID = 0)	of the first shape (shapeID = 0) has two
	  triangles, the format	of the texture index array will	be:

	       1 2 3 -1	4 5 6 -1

	  were indices 1, 2, and 3 are for line	0 and 4, 5, and	6 are
	  for line 1.  The parameter count will	be set to 8.

	  If no	texture	vertices exist the indices array will be set
	  to NULL.  The	indices	array is an internal buffer.  Do not
	  free or modify the index array.


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