From cppreference.com
< cpp‎ | memory‎ | allocator

Defined in header `<memory>` |  |
void deallocate( pointer p, size_type 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`.

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)
