| 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)
