CObList::RemoveHead

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