Yes, It works well. Thank you very much indeed!

2009/5/13 Ke, Liping <liping.ke@intel.com>

please try below test code piece. Hope it could help you.

#include <stdio.h>
#include <stdlib.h>

 

#include <xenctrl.h>

 

int main(int argc, char *argv[] )
{
    int cpu, xc_id;
    if ( argc < 2) {
        printf("Please input offline CPU-id\n");
        exit(0);
    }
    cpu = atoi(argv[1]);
    printf("Offline CPU %d\n", cpu);
    xc_id = xc_interface_open();
    xc_cpu_offline(xc_id, cpu);
    printf("CPU offlined\n");
    xc_interface_close(xc_id);
    return 0;

Thanks a lot.
Is there a sample or tutorial for how to implement the offline process using this library?
