NAME

Intro − introduction to special files

DESCRIPTION

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

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 device driver are discussed where applicable. 

Disk device file names are in the following format:

/dev/{r}dsk/c#t#d#s#

where r indicates a raw interface to the disk, the c# indicates the controller number, #t indicates the SCSI target id, d# indicates the device attached to the controller and s# indicates the section number of the partitioned device. 

Protocols and Protocol Families

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

Major protocols in the Internet family include:

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

• The Transmission Control Protocol (TCP); see tcp(7).  This is the default protocol for SOCK_STREAM type sockets. 

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

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