CAtlList::GetHead
Call this method to return the element at the head of the list.
E& GetHead( ) throw( );
const E& GetHead( ) const throw( );
Return Value
Returns a reference to, or a copy of, the element at the head of the list.
Remarks
If the list is const, GetHead returns a copy of the element at the head of the list. This allows the method to be used only on the right side of an assignment statement and protects the list from modification.
If the list is not const, GetHead returns a reference to the element at the head of the list. This allows the method to be used on either side of an assignment statement and thus allows the list entries to be modified.
In debug builds, an assertion failure will occur if the head of the list points to NULL.
Example
See the example for CAtlList::AddHead.
