CALL SEQUENCE

CALL PQCVF (WTYPE, NRCACT, ERRIND, MNUBSC, NCACT, CACT)

INPUT PARAMETERS

INTEGER WTYPE

Workstation type

INTEGER NRCACT

List element requested of curve approximation criteria types

OUTPUT PARAMETERS

PHIGS STATE

EFFECT

If the inquired information is available, the error indicator is returned as 0 and values are returned in the output parameters.

If the inquired information is not available, the values returned in the output parameters are implementation dependent and the error indicator is set to one of the following error numbers to indicate the reason for non-availability:

ERRORS

2

Ignoring function, function requires state (PHOP, *,*,*)

52

Ignoring function, workstation type not recognized by the implementation

51

Ignoring function, this information is not yet available for this generic workstation type: open a workstation of this type and use the specific workstation type

59

Ignoring function, the specified workstation does not have output capability (i.e. the workstation category is neither OUTPUT, OUTIN, nor MO)

62

Ignoring function, this information is not available for this MO workstation type
