The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE HLHSR IDENTIFIER FACILITIES (PHOP,*,*,*)

Purpose

Use Inquire HLHSR Identifier Facilities to inquire the list of available Hidden Line/Hidden Surface Removal (HLHSR) identifiers on the specified workstation. See Set HLHSR Identifier subroutine for a listing of the possible HLHSR identifiers.

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
57
Specified Workstation Is Of Category MI
62
This Information Not Available For MO Workstation Type

Language Bindings

C

pinq_hlhsr_id_facs (ws_type, num_elems_appl_list, start_ind, err_ind, hlhsr_ids, num_elems_impl_list)

Input Parameters

Pint ws_type
