Hi Kevin, > When memory is released via the C++ "delete" operator, is memory every > released back to the OS (as it is when "free" is used in C)? Under the covers, "delete" uses the C free() routine, for every C++ platform I've used. (Also, "delete" and "delete[]" do other things, so you can't just use free or realloc and have things work as desired.) If your platform's heap management (Standard C's malloc / free) releases heap back to the OS, then the answer is: yes the memory is released back to the OS. In my experience, the stock memory management heap routines with that come with Standard C (malloc, free) do not release heap back to the OS. But that may be indicative of the platforms I've used, not necessarily true for all malloc/free. (I'm sure there are some C++ compilers that do not use malloc/free as part of new/delete... but I can not name any.) HTH, --Eljay
