Creating a struct Type Transformation

This section describes a type transformation that is used with the g++ std::list class. Here is how this class is defined:

template <class _Tp>
struct _List_node {
    typedef void*     _Void_pointer;
    _Void_pointer    _M_next;
    _Void_pointer    _M_prev;
    _Tp     _M_data;
};

This template definition does not contain information that TotalView can use to determine that object pointed to by the next and prev pointers are _List_node objects. Creating a transformation will allow TotalView to display this information in a more orderly way.
