[Lazarus] TFileStream

[Dave Coventry]

Hi AJ.

I was under the impression that this:

 FS:=TFileStream.Create(fname, fmshareDenyWrite);
 Try
   FS.ReadBuffer(hdbuffer[0],32);
 Finally
   FreeAndNil(FS);<-----
 end;

would free the File Pointer to be used again.

Do you suggest that I use another variable when I do it the second time?

Is it possible to specify that the program only uses one thread?

I'm having a lot of unexplained errors in developing this app and I'm
wondering if this isn't the cause of a lot of them.


FS2:=TFileStream.Create(fname, fmshareDenyWrite);

Surely that would fail too?
