allocator::deallocate
Visual Studio 2012
Frees a specified number of objects from storage beginning at a specified position.
void deallocate( pointer _Ptr, size_type _Count );
The member function frees storage for the array of count objects of type Type beginning at _Ptr, by calling operator delete(_Ptr). The pointer _Ptr must have been returned earlier by a call to allocate for an allocator object that compares equal to *this, allocating an array object of the same size and type. deallocate never throws an exception.
For an example using the member function, see allocator::allocate.
