CAtlList::AddHead

Call this method to add an element to the head of the list.

POSITION AddHead( ); 
POSITION AddHead(
   INARGTYPE element 
);

Parameters

  • element
    The new element.

Return Value

Remarks

If the first version is used, an empty element is created using its default constructor, rather than its copy constructor.

Example

// Declare a list of integers
CAtlList<int> myList;

// Add some elements, each to the head of the list.
// As each new element is added, the previous head is
// pushed down the list.
myList.AddHead(42);
myList.AddHead(49);

// Confirm the value currently at the head of the list
ATLASSERT(myList.GetHead() == 49);

// Confirm the value currently at the tail of the list
ATLASSERT(myList.GetTail() == 42);
