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.
Some of the AT&T 3B2 SVR4 documentation set guides include duplicates
of relevant manpages. In this documentation set, all manpages may be
found in the appropriate Reference Manual and, with the exception of
the Programmer's Guide: XWIN Graphical Windowing System, the
Programmer's Guide: OPEN LOOK Graphical User Interface, and the OPEN
LOOK Graphical User Interface User's Guide, are never duplicated in
the guides.
The Reference Manual pages are divided as follows: User's Reference
Manual: Section 1 and all subsections (except 1M). System
Administrator's Reference Manual: Sections 1M, 7 and 8. Programmer's
Reference Manual: Section 2 through 6.
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 system device driver are discussed
where applicable.
For devices other than the mvme328, 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# indicates the
controller number, d# indicates the device attached to the controller
and s# indicates the section number of the partitioned device.
For the format for the mvme328 disk device, see the mvme328(7) manual
page.
