Hi Christof,
>>I can't look into the memory management design, but I recall that FPW 2.x was not able to free unused memory back to the OS.
>That's the "back-end".
>>>And how does garbage collection fit into these layers ? A part of the 'backend' layer or both ?<<
>Which garbage collection? The NTI garbage collection is definitely part of the internal memory system. Reorganizing the handle pool, though, is something that probably the back-end must do. However, I'm not sure that VFP does still do a back-end garbage collection. It was necessary when memory access was limited to physical memory, but with virtual memory, memory mapping, and the like, I'm not sure what role memory fragmentation really plays.
Is there any documentation about this? If not, how do you know this about VFPs memory management ?
Walter,
