Yes, but MANY does not mean ALL. new MAY call malloc internally but the compiler maker is free to choose a completely different storage allocation sheme for objects. And there was a good reason why there is no built in realloc for memory you allocated with new. malloc can't handle objects because it can't deal with contructors and the like. Doing a reallocation for built-in types is easy, but doing the realloc for unknown objects would be very difficult ! And: why do you cross-post this to so many inapropriate groups ?
