DosGetProcessorStatus - Example Code

The following code example shows the use of DosGetProcessorStatus:

#define INCL_BASE
#define INCL_DOSSPINLOCK
#define INCL_DOSERRORS
#include <os2.h>
#include <stdio.h>
#include <string.h>

int main(VOID)
{
    ULONG       ulProcNum   = 0L;         /* Processor number   */
    ULONG       ulStatus    = 0L;         /* Processor status   */
    APIRET      rc          = NO_ERROR;   /* Return code        */

    /* Determine status of processor 0 */

    ulProcNum = 1L;  /* Processors are numbered from 1 to n     */

    rc = DosGetProcessorStatus(ulProcNum, &ulStatus);

    if (rc != NO_ERROR) {
        printf("DosGetProcessorStatus failed:    rc = %u\n", rc);
        return 1;
    } else  {
        printf("Processor %u is %s.\n", ulProcNum,
                (ulStatus ? "OFFLINE" : "ONLINE"));
    }  /* endif */

    return NO_ERROR;

}
