Description

pinq_disp_upd_st queries the workstation state list and returns the current deferral mode, modification mode, display surface empty flag, and the state of visual representation.  If simulated and deferred actions exist simultaneously, the state of visual representation entry is PVISUAL_ST_DEFER.
