Use Set HLHSR Mode to set the requested Hidden Line/Hidden Surface Removal (HLHSR) mode in the workstation state list to the value specified.
If the dynamic modification accepted for HLHSR mode in the workstation description table is set to Immediate (IMM), or if the display surface empty entry in the workstation state list is set to EMPTY, then the graPHIGS API sets the current HLHSR mode in the workstation state list to the specified value and sets the HLHSR update state to NOTPENDING. Otherwise, the graPHIGS API sets the HLHSR update state to PENDING and does not change the current HLHSR mode.
