If `size` is 0, a null pointer is returned with no other effect. If this allocator cannot return the requested number of bytes, then it will return a null pointer. The behavior is undefined unless `0 <= size`. Note that the alignment of the address returned is the maximum alignment for any type defined on this platform. Also note that `std::malloc` is _not_ called when `size` is 0 (in order to avoid having to acquire a lock, and potential contention in multi‐treaded programs). == Synopses Declared in `<bslma_mallocfreeallocator.h>` Return a newly allocated block of memory of (at least) the specified positive `size` (in bytes).
