The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE PREDEFINED POLYLINE REPRESENTATION (PHOP,*,*,*)

Purpose

Use Inquire Predefined Polyline Representation to inquire the predefined polyline attributes in an entry of the bundle table for a specified workstation type.

The graPHIGS API returns the polyline type, width, and color for the specified index of 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
100
Bundle Index Value Is Less Than One
102
Representation Has Not Been Predefined On This Workstation
