CObject* RemoveHead( );
Return Value
The CObject pointer previously at the head of the list.
Remarks
Removes the element from the head of the list and returns a pointer to it.
You must ensure that the list is not empty before calling RemoveHead. If the list is empty, then the Debug version of the Microsoft Foundation Class Library asserts. Use IsEmpty to verify that the list contains elements.
Example
See CObList::CObList for a listing of the CAge class.
CObList list;
CAge* pa1;
CAge* pa2;
list.AddHead( pa1 = new CAge( 21 ) );
list.AddHead( pa2 = new CAge( 40 ) ); // List now contains (40, 21).
ASSERT( *(CAge*) list.RemoveHead() == CAge( 40 ) ); // Old head
ASSERT( *(CAge*) list.GetHead() == CAge( 21 ) ); // New head
delete pa1;
delete pa2;
