memory_resource* new_delete_resource() noexcept;
(library fundamentals TS)

Returns a pointer to a memory_resource that uses the global operator new and operator delete to allocate memory.

[edit] 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 uses ::operator new to allocate memory;
  • its deallocate() function uses ::operator delete to deallocate memory;
  • for any memory_resource r, p->is_equal(r) returns &r == p.

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