Use Inquire HLHSR Mode to inquire the current and requested Hidden Line/Hidden Surface Removal (HLHSR) mode, and the HLHSR update state on the specified workstation. Possible HLHSR modes include: 0=OFF and 1=ON THE FLY.
The HLHSR update state is PENDING if the application has requested an HLHSR mode change but the workstation has not yet provided that change. Otherwise, the update state is NOT PENDING.
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:
|pinq_hlhsr_mode (ws_id, err_ind, upd_st, cur_mode, req_mode)|
|PQHRM (wkid, errind, hupd, chrm, rhrm)|
