Purpose

DosGetProcessorStatus returns the ONLINE or OFFLINE status of each processor of an SMP system. The processor status may be set using DosSetProcessorStatus. ONLINE status imples the processor is available for running work. OFFLINE status implies the porcessor is not available for running work.
