Problem with PIP_ADAPTER_INFO

[Der schöne Günther]

To be honest, I'm really surprised to see some locale string as a device Name. Never seen anything like this. Can you reproduce this on other Computers that also have those names?

In the meantime, let's try GetAdaptersAddresses(..) instead:

Delphi-Quellcode:

program Project1;

{$APPTYPE CONSOLE}
{$R *.res}

uses
   System.SysUtils, // For RaiseLastOSError
   Winapi.IpTypes,
   Winapi.IpHlpApi,
   Winapi.Windows,
   WinApi.WinSock2 // For AF_xxx
;

const
   skipFriendlyName: Boolean = False;
var
   flags: DWORD;
   addresses: PIP_ADAPTER_ADDRESSES;
   buffSize: ULONG;
   returnValue: ULONG;
begin
   flags := 0;
   if skipFriendlyName then
      flags := flags or GAA_FLAG_SKIP_FRIENDLY_NAME;

   addresses := new(PIP_ADAPTER_ADDRESSES);
   buffSize := SizeOf(addresses^);

   returnValue := GetAdaptersAddresses(
      AF_UNSPEC,  // Return both IPv4 and IPv6 addresses associated with adapters with IPv4 or IPv6 enabled.
      flags,
      nil,
      addresses,
      Addr(buffSize)
   );

   // Buffer to small? buffSize already got changed, just do it again
   if returnValue = ERROR_BUFFER_OVERFLOW then
      returnValue := GetAdaptersAddresses(
         AF_UNSPEC,
         flags,
         nil,
         addresses,
         Addr(buffSize)
      );

   if returnValue <> ERROR_SUCCESS then
      RaiseLastOSError();

   while Assigned(addresses) do begin
      WriteLn('Adapter Name: '+addresses.AdapterName);
      WriteLn('Friendly Name: '+addresses.FriendlyName);
      WriteLn('Description: '+addresses.Description);
      WriteLn(sLineBreak);
      addresses := addresses.Next;
   end;

   Readln;
end.

That gets me
