[Openmcl-devel] %get-ip-interfaces returning nil

[Roman Marynchak]

Hi Elliott,

I have tried the same under Win7 x64, but in C. It works fine. You may use
this simple code to figure out the level where the problem is (CL or OS):

#include "stdafx.h"
#include <Winsock2.h>

char data[4096];

int _tmain(int argc, _TCHAR* argv[])
{
 WSADATA wsd;

 if (0 == WSAStartup(0x0202, &wsd)) {
  SOCKET s = socket(AF_INET,SOCK_DGRAM, IPPROTO_UDP);
  if (INVALID_SOCKET != s) {
   DWORD retb;
   if(0 == WSAIoctl(s, 0x4004747f, NULL, 0, &data, 4096, &retb, NULL, NULL))
{
    printf("Success\n");
    getchar();
   }
  }
 }
 return 0;
}


Regards,
Roman
