Hi, a miscdevice enables for easy creation of a char-device. Further, a miscdevice is attached to the class misc; that is, we get a dev attribute exported to the sysfs (/sys/class/misc/.../dev), making udev create a device node for us. Is the miscdevice dedicated to some special purposes (e.g. system devices...)? May driver programmer freely use miscdevices for their purposes? /FAU -- Kernelnewbies: Help each other learn about the Linux kernel.
