The TP7 manual suggests it was possible to partially free the memory. If you had a pointer to the un-freed chunk, I wonder if that could also have been freed, or if was left in limbo.
As the manual suggests, I bet everyone just used SizeOf() as the parameter, and I'm not so sure how useful using freemem like above would be.. -- Alexander Grotewohl https://dcclost.com ________________________________ From: fpc-pascal <fpc-pascal-boun...@lists.freepascal.org> on behalf of Marco van de Voort via fpc-pascal <fpc-pascal@lists.freepascal.org> Sent: Wednesday, December 30, 2020 5:56:45 PM To: FPC-Pascal users discussions <fpc-pascal@lists.freepascal.org> Cc: Marco van de Voort <f...@pascalprogramming.org> Subject: Re: [fpc-pascal] Two versions of freemem() - are they equal Op 2020-12-30 om 23:54 schreef Graeme Geldenhuys via fpc-pascal: > Do both these method yield the same result, or is one better (performance, > safer?) that the other? > > > procedure FreeMem(p:pointer;Size:ptruint); > procedure FreeMem(p:pointer); They are the same. TP required size for deallocation, Delphi and FPC don't. The overload with size is for TP compatibility. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
