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.<br>

As the manual suggests, I bet everyone just used SizeOf() as the parameter, and I'm not so sure how useful using freemem like<span id="ms-outlook-android-cursor"></span> above would be..<br>

They are the same. TP required size for deallocation, Delphi and FPC <br>
don't. The overload with size is for TP compatibility.<br>
