      (
      var sdRef: TDNSServiceRef;
      const flags: TDNSServic         


        

Answer 1

If the DLL is not written using Delphi 2009, you may want to use something else than PUTF8String. The Delphi 2009 Utf8String type is different from Delphi 2007's UTF8String type.

If the DLL was written using C/C++, I strongly suggest to use PAnsiChar() instead of PUtf8String.
