Hi, This is true, but in theory, malloc doesn't have a notion of a virtual or physical address space. Malloc is defined as : it tries to allocate a contiguous memory chunk of at least the required size in a system-defined pool. The question of setting up virtual address spaces, of lazy allocation of physical pages, etc. is left up to the underlying OS. In other terms : it's mmap(2) and brk(2) that take care of this. Malloc relies on them for this kind of questions.
