TYPES

typedef enum {
	PUPD_NOT_PEND,
	PUPD_PEND
} Pupd_st;

typedef struct {
	Pfloat	x_min;	/* minimum x 	*/
	Pfloat	x_max;	/* maximum x 	*/
	Pfloat	y_min;	/* minimum y 	*/
	Pfloat	y_max;	/* maximum y 	*/
	Pfloat	z_min;	/* minimum z 	*/

PHIGS STATE

(PHOP, WSOP, *, *).

EFFECT

Returns workstation ws_id's workstation transformation update state as well as the requested and current window and viewport in the workstation state list. If the data is available, error indicator is returned as 0.

The workstation transformation update state is PUPD_PEND when a modification has been requested but is not yet effective.

ERRORS

3: Ignoring function, function requires state (PHOP, WSOP,*,*)
54: Ignoring function, the specified workstation is not open
57: Ignoring function, specified workstation is of category MI
