Inheritance diagram for mach_allocator:
Puts the Standard C++ Allocator interface on the Mach VM allocator. This is the fundamental allocator on the OS X system, whose main characteristic is that it allocates pages "lazily" i.e. memory is not actually allocated until it is accessed. Also allocated memory is always page-aligned and zero-filled.
This lets you use Mach allocators to allocate memory for STL containers and C++ objects. All allocator instances are not distinct and compare equal.

| bool | operator!= (const mach_allocator &, const mach_allocator &) |
| Tests whether left and right are different allocators. Always false. | |
| bool | operator== (const mach_allocator &, const mach_allocator &) |
| Tests whether left and right are the same allocator. Always true. | |
