This time, I'll give an example of something which could be exported. *nb* Some of the code in this article has changed somewhat to the previous ..

This time, I'll show how to change things so that we can write things into kernel space via the proc filesystem, and then read them back. /* * /proc file driver. */ #define TEST_VERSION "1.0" #include #include #include #include #include static int pr..
