The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE POLYLINE FACILITIES (PHOP,*,*,*)

Purpose

Use Inquire Polyline Facilities to inquire the polyline facilities for the specified workstation type.

The graPHIGS API returns the total number of available line types and their identifiers; the number of available line widths and the nominal, minimum, and maximum line width size; and the number of predefined polyline bundle table indexes for the specified workstation type.

If the information is available, then the graPHIGS API sets the error indicator to zero and returns the values in the output parameters. If the information is unavailable, then the values returned in the output parameters are 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

Language Bindings
