The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE PATTERN FACILITIES (PHOP,*,*,*)

Purpose

Use Inquire Pattern Facilities to inquire the pattern facilities for the specified workstation type.

The graPHIGS API returns the number of predefined pattern indexes for the specified workstation.

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
