Special files for char drivers are identified by a "c" in the first column of the output of ls -l. Anyone can compile and run scull, and scull is portable across the computer architectures on which Linux runs. Another significant disadvantage is the slow execution speed and the need to launch a new process for almost every shell command executed.Chapter 3 Char Drivers Contents: The Design of scull Major and Minor Numbers File Operations The file Structure open and release scull's Memory Usage.
