void deallocate(T* p, std::size_t n );
(since C++17)

Deallocates the storage pointed to by p, which must have been allocated from a std::pmr::memory_resource x that compares equal to *resource() using x.allocate(n * sizeof(T), alignof(T)).

Equivalent to this->resource()->deallocate(p, n * sizeof(T), alignof(T));

[edit] Parameters

p - pointer to memory to deallocate
n - the number of objects originally allocated

[edit] Exceptions

Throws nothing.
