Hi,

was that right this time?

It didn't seem to make sense to add this to the patch, so I'm appending the
program I used for testing the hypercall patch here just for completeness:

#include <stdio.h>
#include <errno.h>
#include <xenctrl.h>

int main(void) {
xc_interface *xch = xc_interface_open(NULL, NULL, 0);

int ver = xc_version(xch, XENVER_version, NULL);

printf("Xen Version %d.%d\n", ver >> 16, ver & 0xffff);

    int domid = xc_domid(xch);

printf("Xen domain: %d\n", domid);

    if(domid == -1) {
        printf("errno=%d (%s)\n", errno, xc_strerror(xch, errno));
    }

xc_interface_close(xch);

return 0;
}
