Does FastMM detect all memory leaks

Question

Somebody suggested recently ( My program never releases the memory back. Why? ) that my program leaks some memory. I have FastMM set to aggressive and it reports no memory l

Answer 1

FastMM is a layer on top of Windows memory management. Obviously, if you (or some component or whatever) uses Windows APIs to allocate memory, then such allocation bypasses FastMM and you won't be able to track it. BTW Delphi memory managers themselves use that APIs to allocate chunks of memory. So if you need to see allocations on that level, FastMM is not enough - you must use tools like AQTime and similar (as I suggested in the previous question).
