DosGetProcessorStatus

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 processor is not available for running work.

Syntax
APIRET DosGetProcessorStatus (ULONG procid, PULONG status)

Parameters

 * procid (ULONG) input:Processor ID numbered 1 through n, where there are n processors in total
 * status (PULONG) output:Status is defined as follows
 * PROC_OFFLINE 0x00000000 Processor is offline
 * PROC_ONLINE 0x00000001 Processor is online

Return Code

 * ulrc (APIRET) returns:DosGetProcessorStatus returns one of the following values
 * 0 NO_ERROR
 * 87 ERROR_INVALID_PARAMETER
