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

Since C++17

void deallocate( T* p, std::size_t n );

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));.

Parameters

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

Exceptions

Throws nothing.
