Delphi 2.0 And VC++ DLL Usage

Hi,

This is a tricky one. I am using Delphi 2.0 to call some routines in a
VC++ DLL. The DLL routines return pointers to memory blocks that I must
free. How do I do this?

Many thanks

By asking only in Delphi newsgroups.

I'm afraid you are missing something... :) If you want to kill your
program
very fast - allocate something in DLL with new, malloc, GetMem,
whatever, pass
this pointer back to application and try to free it there :)))

What it could be that DLL allocates memory with GlobalAlloc, but then
you should
get memory handle, not pointer... So check it out again

Cheers
Dmitri
