The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference
INQUIRE WORKSTATION CLASSIFICATION (PHOP,*,*,*)
Purpose
Use
Inquire Workstation Classification
to inquire the display classification of the specified
workstation type.
The graPHIGS API returns a value indicating the type of display technology
utilized by the specified workstation type.
Possible classifications include: VECTOR,
RASTER, and OTHER.
If the information is available, then the graPHIGS API sets the
error indicator to zero and returns the display classification
in the output parameter.
If the information is unavailable,
then the value returned in the output parameter
is unpredictable and the graPHIGS API sets the error indicator
to one of the following errors:
- 2
- Function Requires State (PHOP,*,*,*)
- 52
- Workstation Type Not Recognized By Implementation
- 51
- Information Not Available For Generic Workstation Type
- 59
- Specified Workstation Does Not Have Output Capability
- 62
- This Information Not Available For MO Workstation Type
