This sounds like you need an introductory C class. Did you remember to #include them? Oh, by the way, keep in mind that the Linux kernel "linked list" is actually a circularly linked list - as a result, treating it as a normal linked list (particularly when checking for empty list or end-of-list) is likely to result in hilarity and hijinks for all... > Would it be okay to modify the variable/function names in a copy of list.h > and use it in the userspace program ? You'd probably be better off learning basic data structures well enough to write your own implementation.
