(library fundamentals TS)

Returns a pointer to a memory_resource that doesn't perform any allocation.

Return value

Returns a pointer p to a static storage duration object of a type derived from std::experimental::pmr::memory_resource , with the following properties:

  • its allocate() function always throws std::bad_alloc ;
  • its deallocate() function has no effect;
  • for any memory_resource r , p->is_equal(r) returns &r == p .

The same value is returned every time this function is called.
