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 them-
selves. Characteristics of both the hardware device and the
corresponding UNIX system device driver are discussed where
applicable.
Disk device file names are in the following format:
/dev/{r}dsk/c#d#s#
where r indicates a raw interface to the disk, the c# indi-
cates the controller number, d# indicates the device
attached to the controller (unit number) and s# indicates
the partition number of the disk.
