    how to use this linked list?

    can someone tell me how to create an instance of this linked list and add a member to it?

    Code:
    template<class T>
    class LinkedList : public BaseRefCollection<T> {
    public:
        typedef T MemberType;
        LinkedList() : version_(0),members_(0),head_(0),tail_(0) {}
        LinkedList( LinkedList<T> * ll ) : head_(ll->head()) {}
    
        const T * head() const { return head_.ptr(); }
        T * head() { return head_.ptr(); }
        void newMember( T * _newMember ) {
          if( tail_ ) {
             tail_->llNextIs(_newMember);
          }
          else head_ = _newMember;
          _newMember->llNextIs(0);
          tail_ = _newMember;
          ++version_;
          ++members_;
        }
        void newMember( const typename T::Ptr& _newMember ) {
           newMember(_newMember.ptr() );
        }
    
        .
        .
        .
    
    }
    this line works:
    LinkedList<myType> linkedList();

    do i need to allocate memory for it before i can add a member, and how do i add a member?

    Thanks!

    This isn't C, and the code is messy. Looks like you just hand it a pointer to whatever paramaterized type you gave the list. In your case a * myType to the newMember method.

    Is there a reason you aren't using the standard std::list in the <list> header?

    Perhaps finding a C example may be clearer to you. I think you are having trouble since this is a C++ class. If you are learning C. A C++ class will just look quite confusing.

    Perhaps the poor soul is actually doing C and found some C++ code and was wondering WTF is this and how do I use it?

    Outside of your DOS world, your header file is meaningless.

    I think that is probably the case. They may be similar languages, but any template will baffle someone not acquainted with C++.
