Description

PQHRM queries the workstation state list and returns the HLHSR update state, the current HLHSR mode, and the requested HLHSR mode.  If an application requested an HLHSR mode change but Digital PHIGS did not provide one before the application called this function, the HLHSR update state is PPEND.
