std::pmr::polymorphic_allocator
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) ) ;

Parameters

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

Exceptions

Throws nothing.
