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

Deallocates the storage pointed to by p, which must have been allocated from a 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.
