And when you attempt to rename the table, what happens? The virtual table interface is advanced, in the sense that there are very few safety nets or double-checks. It is designed to be used by an intelligent programmer that knows their stuff. You need to do what the docs say, exactly, or something bad can happen. That's not to say something bad will happen right away. The fact that you can assign a NULL function pointer to the xRename() function only means the system is not double-checking your work when you pass in the structure... it does not mean that passing a NULL is allowed. I strongly suspect that if you do not provide a xRename() function, and someone attempts to rename the table, the whole application will simply crash. Your fault. -j -- Jay A.
