PHIGS STATE
(PHOP, WSOP, *, *).
EFFECT
Returns the components contained in the specified view representation of the
view table in workstation WKID's workstation state list. If the
inquired information is available, the error indicator is returned as 0 and
values are returned in the output parameters.
UPDATE STATE is pending if a view modification request has been made but not
yet updated.
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
- 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
- 114
- Ignoring function, the view index value is less than zero
- 101
- Ignoring function, the specified representation has not been
definded
