Exporting same DLL function under multiple names

I have made some functions in my DLL, like this:

procedure DoThis(A: PChar): Boolean; stdcall;
begin
f := TFileStreamCreate(A, fmCreate);
f.read()
f.free;
end;

then I exported it under 2 names:

export
  DoThis,
  DoThis name 'DoThat';

In most cases this "renaming" works. But in at least one case the renamed function "DoThat" does not read data from a real file but from the void. If I call DoThis on the same file- it works great. I removed all memory leaks thanks to FastMM4 (converted the code to regular console app)

So the question is:

Is this "renaming" not a legal thing to do?

If it is legal- can I debug DLL with FastMM4 without changing it into a console app?

Solution

  • What you describe in the question is not consistent with reality.

    Is this "renaming" not a legal thing to do?

    Exporting the same function under multiple names is perfectly legal. The problems you describe do not happen.

    Can I debug DLL with FastMM4 without changing it into a console app?

    Yes you can. Specify a host application in the Run parameters dialog and you can debug your DLL.
