How to write a buffer to a TStream ?

Hi!

How can I copy a buffer to a TStream ?

I have the following code and it doesn't work:

var
  Stream : TStream;
begin
  Stream.Size := MaxBufferSize;
  Stream.Position := 0;
  Stream.Write(Buffer, Buffer_Length);
end

where Buffer is a Pchar containing the data and Buffer_Length is the length of Buffer.  MaxBufferSize is the max size of Buffer.

On the other hand,  If I do the following it works fine:
var
  Stream : TStream;
  List : TStringList;
begin
  Stream.Size := 0;
  Stream.Position := 0;
  List := TStringList.Create;
  List.Text := Buffer;
  List.SaveToStream(Stream);
  List.Free;
end;

Can somebody please tell me how exactly should I write the 'Buffer' to the stream ? ... The problem with using a TStringList is that the buffer might contain binary data instead of text.

BTW, the above code is just an example, ... that's the reason why I omited the creation of the stream, etc ..
Thanks a lot

If buffer is a pchar, then it should be

Stream.Write(Buffer^, Buffer_Length);

writing the buffer using Delphi Strings

procedure WriteBuffer(S: TStream; Text: String);
var
  Size: Integer;
begin
  Size := Length(Text);
  if Size > 0 then begin
    S.Write(PChar(Text)^,Size);
  end;
end;
