new is not a wrapper of malloc(). It is an entity of its own. In fact
malloc() should not be used in C++ because it does not call the object's
costructor. Also there is no guarantee that even for POD types new, delete
and the malloc() family,free() are interoperable.

I do not know what a Far pointer, but I do know that they exist. Can you
tell us what does it mean?



You can overide the operator new to define its functionality (e.g. to
provide space from an array of yours in the stack). It is what TC++PL names
"placement operator new".
