          NAME
               intro - introduction to special files

          DESCRIPTION
               This section describes various special files that refer to
               specific hardware peripherals and UNIX system device
               drivers.  STREAMS [see intro(2)] software drivers, modules,
               and the STREAMS-generic set of ioctl(2) system calls are
               also described.

               For hardware-related files, the names of the entries are
               generally derived from names for the hardware, as opposed to
               the names of the special files themselves.  Characteristics
               of both the hardware device and the corresponding UNIX sys-
               tem device driver are discussed where applicable.

               Disk device file names are in the following format:

                                     /dev/{r}dsk/#s#

               where r indicates a raw interface to the disk, the first #
               indicates the drive number, and the second # indicates the
               section number of the partitioned device.
