Detailed Description

template<typename _Tp, typename _Alloc>
class std::_Deque_base< _Tp, _Alloc >

Deque base class. This class provides the unified face for deque's allocation. This class's constructor and destructor allocate and deallocate (but do not initialize) storage. This makes exception safety easier.

Nothing in this class ever constructs or destroys an actual Tp element. (Deque handles that itself.) Only/All memory management is performed here.

Member Function Documentation

_M_initialize_map()

template<typename _Tp , typename _Alloc >

void std::_Deque_base< _Tp, _Alloc >::_M_initialize_map ( size_t  __num_elements )

protected

Layout storage.

Parameters

__num_elements

The count of T's for which to allocate space at first.

Returns

Nothing.

The initial underlying memory layout is a bit complicated...
