The procedure in my user program is:

I can't figure out how to get the characters in the Buffer (type of
Pointer) into a string that I can use in a memo control.

Try:

Memo1.Lines.Append(PChar(Buffer));

Better yet:

var
s: AnsiString;
begin
SetString(s, Buffer, BufferLength);
Memo1.Lines.Add(s);
end;

The presence of a BufferLength parameter suggests that there won't necessarily be a null character marking the end of the buffer. There might even be null characters in the middle of the buffer.
