I'm not sure whether I should be asking here or on one of the FPC lists. Furthermore I'm sure I've seen this discussed previously but can't find it- my apologies.

Is there a simple function or variable which shows the amount of space currently allocated on the heap? I can't find the Lazarus/FPC equivalent of Delphi's AllocMemSize, and I'm looking for a simple metric I can place in a hint to warn of creeping leaks.

Look for GetHeapStatus, it's even compatible with Delphi (if that's necessary).

Hint: compile application with -gh, that will use heap tracer and tell you at end of application where your leaked blocks are coming from.

Thanks, just the job. It's a hack when I'm leaving a serial comms program looping so I can see what happens when things have settled down, no plans to port to Delphi although I might make sure the library works with Windows.

Thanks for that as well :-)
