copied!<p>create a class and overload new only in this class. you will not have problems with your vector. you will be able to use your own new with <code>::new A</code> and the normal new with <code>new A</code></p> <pre><code>class C { public: void* operator new( size_t n ) ; // ... } ; </code></pre> <p>otherwise, you can use your own <s>operator</s> function rather than overload operator new : </p> <p>a basic idea of an allocator :</p> <pre><code>int *i = myGetMem(i); // and myGetMem() allocates sizeof(*i) bytes of memory. </code></pre> <p>so you will not have problems with using the vector.</p> <hr> <p>in fact, a real memory allocator keeps the information you put on the vector in the memory allocated it self : </p> <p>you can take an algorithm for getmem/freemem to adapt it to your case. it can be helpfull.</p> <p>e.g. : i want to allocate 10 bytes, the memory at @1024 contain information about memory allocated and the allocator returns an adress after 1024, maybe @1030 (depending of the information stored) as the start of allocated memory. so the user gets adress 1030 and he has memory between 1030 and 103A.</p> <p>when calling the deallocator, the information at the beginning is used to correctly free the memory and to put it back in the list of avaible memory.</p> <p>(the list of availvle memory is stored in popular alorithms in an array of linked lists of free memories organized by size with algorithms to avoid and minimize fragmentation)</p> <p>this can resolve your need to the vector.</p>
