    Weird Destructor Error

    I get a weeeird error when defining my destructor, it uses another function Purge() to accomplish the job..

    Code:
    template <class T> // LinkedList Member Function, cleans up List Elements, Purges them
    void LinkedList<T>::Purge()
    {
    	while (head != 0)
    	{
    		ListElement<T>* const tmp = head;
    		head = head->next;
    		delete tmp;
    	}
    	tail = 0;
    }
    
    template <class T> // Destructor, uses purge!
    void LinkedList<T>::~LinkedList()
    { Purge (); }
    Here is the error..
    Code:
    c:\documents and settings\jonathan\my documents\c++ programming\opengl with nehe\nehe tutorials\tutorials databasing\single_linked_list.h(82) : error C2631: 'LinkedList<T>::~LinkedList<T>' : destructors not allowed a return type
    What do I do?
    Sometimes I forget what I am doing when I enter a room, actually, quite often.

    just as an aside, you might want to look at boost:tr_vector for this kind of "container of new'd objects". it'll make your life easier

    If you program in C++, you need Boost. You should also know how to use the Standard Library (STL). Want to make games? After reading this, I don't like WxWidgets anymore. Want to add some scripting to your App?
