Intro(7)		 Device	and Network Interfaces		      Intro(7)

NAME
       Intro, intro - introduction to special files

DESCRIPTION
       This section describes various device and network interfaces  available
       on the system.  The types of interfaces	described   include  character
       and  block  devices,  STREAMS modules, network protocols, file systems,
       and ioctl requests for driver subsystems	and classes.

       This section contains the following major collections:

       (7D)	The system provides drivers for	a variety of hardware devices,
		such  as  disk,	 magnetic  tapes,  serial communication	lines,
		mice, and frame	 buffers, as well as virtual devices  such  as
		pseudo-terminals and windows.

		This  section  describes  special files	that refer to specific
		hardware peripherals  and  device  drivers.  STREAMS	device
		drivers	 are also described. Characteristics of	both the hard-
		ware device and	the corresponding device driver	are  discussed
		where applicable.

		An application accesses	a device through that device's special
		file. This section specifies the device	 special  file	to  be
		used  to  access the device as well as application programming
		interface (API)	information relevant to	the use	of the	device
		driver.

		All  device  special  files  are  located  under the  /devices
		directory.  The	 /devices directory hierarchy attempts to mir-
		ror  the  hierarchy of system busses, controllers, and devices
		configured on the system.   Logical device names  for  special
		files  in  /devices  are  located  under  the  /dev directory.
		Although not every special file	under  /devices	 will  have  a
		corresponding logical entry under  /dev, whenever possible, an
		application should reference a device using  the logical  name
		for  the device. Logical device	names are listed in the	 FILES
		section	of the page for	the device in question.

		This section also describes driver configuration where	appli-
		cable. Many device drivers have	a driver configuration file of
		the  form   driver_name.conf   associated   with   them	  (see
		driver.conf(4)).  The configuration information	stored	in the
		driver configuration file is used to configure the driver  and
		the  device.  Driver configuration files are located in	 /ker-
		nel/drv	and  /usr/kernel/drv.  Driver configuration files  for
		platform  dependent  drivers  are  located in /platform/`uname
		-i`/kernel/drv	where	`uname	-i`  is	 the  output  of   the
		uname(1) command with the  -i option.

		Some  driver configuration files may contain user configurable
		properties. Changes in a driver's configuration	file will  not
		take  effect  until  the  system is rebooted or	the driver has
		been removed and re-added (see	rem_drv(1M) and	 add_drv(1M)).

       (7FS)	This section describes the  programmatic interface for several
		file systems supported by SunOS.

       (7I)	This section describes ioctl requests which apply to  a	 class
		of  drivers  or	 subsystems. For example, ioctl	requests which
		apply to most tape devices are	discussed in  mtio(7I).	 Ioctl
		requests  relevant to only a specific  device are described on
		the man	page for that device. The page for the device in ques-
		tion  should  still  be	 examined for exceptions to the	ioctls
		listed in section 7I.

       (7M)	This section describes	STREAMS	modules.  Note	that   STREAMS
		drivers	 are  discussed	in section 7D. streamio(7I) contains a
		list of	ioctl requests used to manipulate STREAMS modules  and
		interface with the STREAMS framework.  Ioctl requests specific
		to a  STREAMS module will be discussed on  the	man  page  for
		that module.

       (7P)	This  section describes	various	network	protocols available in
		SunOS.

		SunOS supports both  socket-based  and	STREAMS-based  network
		communications.	 The  Internet	protocol  family, described in
		inet(7P), is the primary protocol family supported  by	SunOS,
		although  the  system can support a number of others.  The raw
		interface provides low-level services, such as packet fragmen-
		tation	and  reassembly, routing, addressing, and basic	trans-
		port for socket-based implementations.	Facilities for	commu-
		nicating  using	 an  Internet-family  protocol	are  generally
		accessed by specifying the AF_INET address family when binding
		a socket; see socket(3SOCKET) for details.

		Major protocols	in the Internet	family include:

		  o  The  Internet  Protocol  (IP)  itself, which supports the
		     universal datagram	format,	as described in	 ip(7P).  This
		     is	 the default protocol for SOCK_RAW type	sockets	within
		     the AF_INET domain.

		  o  The Transmission Control  Protocol	 (TCP);	 see  tcp(7P).
		     This  is  the default protocol for	SOCK_STREAM type sock-
		     ets.

		  o  The User Datagram Protocol	(UDP); see  udp(7P).  This  is
		     the default protocol for SOCK_DGRAM type sockets.

		  o  The Address Resolution Protocol (ARP); see	arp(7P).

		  o  The   Internet   Control  Message	Protocol  (ICMP);  see
		     icmp(7P).
