AF_HYPERV address family not supported

[Biswapriyo Nath]

Here is the sample code that I've tried.

#include <sys/socket.h>
#include <stdio.h>
#include <errno.h>

#ifndef AF_HYPERV
#define AF_HYPERV 34
#endif

int main(void)
{
int s = socket(AF_HYPERV, SOCK_STREAM, 0);
   if (s > 0)
       printf("success\n");
   else
       printf("%s\n", strerror(errno));
}

Is this by-design? Or am I doing anything wrong?
