                    | void deallocate( T* p, std::size_t n ); | ||
Deallocates the storage referenced by the pointer p, which must be a pointer obtained by an earlier call to allocate(). 
The argument n must be equal to the first argument of the call to allocate() that originally produced p; otherwise, the behavior is undefined.
Calls ::operator delete(void*), but it is unspecified when and how it is called.
[edit] Parameters
| p | - | pointer obtained from allocate() | 
| n | - | number of objects earlier passed to allocate() | 
[edit] Return value
(none)
