Re: [fpc-pascal] question about FPC heap and threading

Looking at heap.inc I see that the "freelists" variable is a threadvar, which indicates to me that each thread has its own heap. If that's the case and also applies to Lazarus it's going to save me a lot of effort, so I'd be interested to see this confirmed as well. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

If lazarus doesn't install it's own heap manager, it is true for Lazarus as well.
