TYPES

typedef struct {
	Pint	num_points;	/* number of Ppoint3s in the list	*/
	Ppoint3	*points;	/* list of points	*/
} Ppoint_list3;

typedef struct {

EFFECT

Example:

/* Sample stroke on workstation number 1 using device number 1 */
	Pint ws_id,stroke_dev;view_index;
	Ppoint points[10];
	Ppoint_list stroke_pos  ;
	.....
	ws_id = 1;
	stroke_dev = 1;
	stroke_pos.points = points;
	psample_stroke(ws_id,stroke_dev,&view_index,&stroke_pos);
	......
