std::pmr::polymorphic_allocator<T>::deallocate - std::pmr::polymorphic_allocator<T>::deallocate


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));


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


Throws nothing.
