I assume that you are aware that you have two ways of introducing user defined memory organization: - by providing your own global (de)allocation functions - by overloading the (de)allocation functions in classes or class templates Back to top Hendrik Schober Guest Posted: Wed Apr 18, 2007 1:43 am    Post subject: Re: About overloading new operator Vladimir Grigoriev <vlad.moscow (AT) mail (DOT) ru> wrote: Quote: Do anybody have any good references for articles about overloading new operator that based on user defined memory organizations. I forgot about earlier editions, but in its 3rd, Scott Meyers "Effective C++" has a whole chapter about 'new' and 'delete' including at least one item about overloading them. While I think bying the book just for this might be a bit overkill, it's a book every C++ programmer should have read anyway, so you wouldn't only buy it for this. :) Quote: Vladimir Grigoriev Schobi -- SpamTrap (AT) gmx (DOT) de is never read I'm HSchober at gmx dot org "My hope is that if more people start reading books, the world will become a better place." froarulv in afp Back to top Vladimir Grigoriev Guest Posted: Wed Apr 18, 2007 1:44 pm    Post subject: Re: About overloading new operator Thanks. I have an old C program that uses a big structure in which different in fact "classes" are placed. The structure is used by several tasks. I'd like rewrite the program as a C++ program and substitute the structure for classes which allocated in a predefined common memory. This is the first task. The second task is that that other "objects" get their memory from a memory organaised as linked lists. And the third task is use own allocator for standard containers that also based on linked lists.

And the third task is use own allocator for standard containers that also based on linked lists. I'm not sure I understand all of this right, but here's what I would do based on what I thought I understood: I would make it a straight-forward C++ programm which does its job and is implemented so that it's easily understood. /Then/ I would check whether it's too slow. /If/ so, I'd profile. /If/ the slowness turns out to be caused by memory allocations/deallocations, I'd look at which classes' allocations cause that. /Then/ I would consider writing one or several allocators for /those/ classes. Of course, there are some programs where you know from experience that this will be necessary. However, you don't necessarily know /where/ in those programs it is necessary without profiling. Also, that the design of a performance-critical app puts performance close to the top of its list of considerations goes without saying. But manually tweaking memory management isn't a design issue and can, in C++, be added later (if needed) without too much hassle. HTH.
