AF_UNIX with Windows 10 and 11

[rogerwimbert-rldatix]

Since 2018 Windows is capable of handling AF_UNIX. See: https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/
As we (RLDatix.com Germany) are now intending to use ACE, and have used AF_UNIX under Windows 10 since Build 17763, we were very surprised to find out that ACE cannot handle this but says "I'm pretty sure NT lacks these" in config-win32-common.h and defines ACE_LACKS_UNIX_DOMAIN_SOCKETS.

Is there a chance, that a (near) future release of ACE will support AF_UNIX under Windows? For compatibility you can insert a check for the right version like this (vi is our internal structure for windows version information):

union {
     DWORD dw;
     char  str[128];
   } data;
   DWORD data_len,error;
   LSTATUS regerr;

   // Version from Registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
   // Versionsinfo: https://docs.microsoft.com/en-us/windows/release-information/

   if((regerr=RegOpenKeyExA(HKEY_LOCAL_MACHINE,"SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion",
                   0,KEY_READ,&syskey)) == ERROR_SUCCESS)
   {
      data_len = sizeof(data);
      error = RegQueryValueExA(syskey,"CurrentMajorVersionNumber",NULL,&type,(LPBYTE)&data,&data_len);
      vi->os_version_major = data.dw;
      data_len = sizeof(data);
      error = RegQueryValueExA(syskey,"CurrentMinorVersionNumber",NULL,&type,(LPBYTE)&data,&data_len);
      vi->os_version_minor = data.dw;
      data_len = sizeof(data);
      error = RegQueryValueExA(syskey,"CurrentVersion",NULL,&type,(LPBYTE)&data,&data_len);
      CPYN(vi->os_version,data.str, sizeof(vi->os_version));
      data_len = sizeof(data);
      error = RegQueryValueExA(syskey,"ProductName",NULL,&type,(LPBYTE)&data,&data_len);
      CPYN(vi->os_system,data.str, sizeof(vi->os_system));
      data_len = sizeof(data);
      error = RegQueryValueExA(syskey, "CurrentBuild", NULL, &type, (LPBYTE)&data, &data_len);
      vi->os_build = (DWORD)atoi(data.str);
      data_len = sizeof(data);
      error = RegQueryValueExA(syskey, "ReleaseId", NULL, &type, (LPBYTE)&data, &data_len);
      if (!error)
          vi->os_release = (DWORD)atoi(data.str);
      else if (vi->os_version_major == 10)
          vi->os_release = 1507;    // In der ersten Version von Windows 10 stand die ReleaseId nicht drin
      else
          vi->os_release = 0;
      data_len = sizeof(data);
      error = RegQueryValueExA(syskey, "UBR", NULL, &type, (LPBYTE)&data, &data_len);
      if (!error)
          vi->os_patch = data.dw;
      else
          vi->os_patch = 0;

      RegCloseKey(syskey);

      vi->afunix_support = (vi->os_version_major >= 10 && vi->os_build >= 17763)?1:0;  // Build 17763 Redstone 5, Version 1809, Oktober 2018 Update vom 13. November 2018; Windows Server 2019

   }

Thanks, Roger
