std::pmr::new_delete_resource - std::pmr::new_delete_resource


Defined in header <memory_resource>
std::pmr::memory_resource* new_delete_resource() noexcept; (since C++17)

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

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 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.
