Returns a pointer to a memory_resource that doesn't perform any allocation.
[edit] Return value
Returns a pointer p to a static storage duration object of a type derived from std::pmr::memory_resource, with the following properties:
- its
allocate()function always throws std::bad_alloc; - its
deallocate()function has no effect; - for any
memory_resourcer,p->is_equal(r)returns&r == p.
The same value is returned every time this function is called.
