memory_resource* null_memory_resource()noexcept; | (library fundamentals TS) | |
Returns a pointer to amemory_resource
that doesn't perform any allocation.
Returns a pointerp
to a static storage duration object of a type derived fromstd::experimental::pmr::memory_resource, with the following properties:
allocate()
function always throwsstd::bad_alloc;deallocate()
function has no effect;memory_resource
r
,p->is_equal(r)
returns&r == p
.The same value is returned every time this function is called.
