CObject* RemoveHead();
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 library asserts. Use IsEmpty to verify that the list contains elements.
The CObject pointer previously at the head of the list.
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;
