I've written a test code below and select() also blocks.

Is there something wrong in it, or in fake_socket_pair ?

#include <stdio.h>
#include <unistd.h>
#include <errno.h>
#include <winsock2.h>

#define FDREAD  0
#define FDWRITE 1

int
main (int argc, char *argv[])
{
   int sockets[2];
   WSADATA  version_data;
   int *i;
   void *buf[1];
   int ret;
   fd_set         rfds;

   FD_ZERO(&rfds);

   WSAStartup(MAKEWORD(2, 2), &version_data);

   if (fake_socketpair(sockets) < 0)
     {
       printf ("error\n");
       return -1;
     }
   FD_SET(sockets[FDREAD], &rfds);
   i = (int *)malloc(sizeof (int));
   *i = 1;
   buf[0] = i;
   write(sockets[FDWRITE], buf, sizeof(buf));
   printf (" * select : select %d %d\n", sockets[0], sockets[1]);
   ret = select(sockets[FDREAD] + 1, &rfds, NULL, NULL, NULL);
   printf (" * select : ret %d\n", ret);
   if (ret < 0) return -1;
   if (ret > 0)
     {
       int len;
       int *j = 0;

       printf ("bon \n");
       while ((len = read(sockets[FDREAD], buf, sizeof(buf))) > 0)
         {
           if (len == sizeof(buf))
