ccsync(7) -- Power Fortran join accelerator.

This device is used by Power Fortran to speed up join synchronization. |

cdsio(7) -- 6-port serial I/O
|
|
6-port boards can be used for modems or other asynchronous, serial I/O devices. The ports provided by the cdsio board are very similar to the on-board duart ports. Various character echoing and interpreting parameters can be set independently for each port. See termio(7) for details. By opening either the ttyd*, ttym*, or ttyf* device name of a port, different hardware signals are supported. Ttyd* is typically used for direct connect devices such as terminals; ttym* is used for devices that use ... |

cl(7) -- CrayLink Driver
|
|
The cl module provides a raw device interface to XPC (cross partition communication). These devices take advantage of the XPC rendezvous capabilities to allow DMA transfers directly from the source to the destination without any intermediate copying if possible. The DMA operation is done using the BTE which supports transfers of multiple cache lines on cache line boundaries. Therefore, in order to avoid the overhead of the cl driver copying data to an intermediate buffer, the source ... |

clone(7) -- open any minor device on a STREAMS driver
|
|
Multiple opens of the same minor device cannot be done through the clone interface. Executing stat(2) on the filesystem node for a cloned device yields a different result from executing fstat(2) using a file descriptor obtained from opening the node. |

cserialio(7) -- character driver interface to serial communication ports
|
|
On Origin, O2, Octane and Challenge/Onyx systems, the special files /dev/ttyc* provide a character based interface (as opposed to a streams based interface) to the system serial ports. The hardware accessed by each special file is determined by the portno portion of the pathname (see serial(7) for further details). The character based interface is intended to provide a low cost option for applications wishing to do bulk data transfer via the serial ports with no character interpretation. There i... |

db(7) -- local name service database
|
|
The db client library fetches name service data out of an db(3B) format database file on the local host. This library is meant to be used only by the nsd(1M) daemon to efficiently access local name service data. The library /var/ns/lib/libns_db.so is opened by the nsd(1M) daemon when db is listed as the protocol for some map in a nsswitch.conf file. The library contains code to fetch data from a local db file and present it as lines from the configuration file from which it came. The nsd daemon ... |

dksc(7) -- dksc (SCSI) disk driver
|
|
The dksc driver supports all disk types that use a SCSI command set. This includes traditional parallel SCSI as well as Fibre Channel Arbitrated Loop and Fibre Channel Fabric devices (devices connected through a Fibre Channel switch). Currently, 8 bit parallel SCSI (also called narrow SCSI) allows up to seven SCSI drives attached per SCSI bus, 16 bit parallel SCSI (also called wide SCSI) allows 15 drives. Fibre Channel Arbitrated Loop (FC-AL) allows up to 125 drives (some implementations limit t... |

dlpi(7) -- data link provider interface
|
|
A.) Snif master file and interfaces The DLPI includes three master files: /var/sysgen/master.d/llc2, /var/sysgen/master.d/xtimer, and /var/sysgen/master.d/snif. You should not need to change the llc2 master file and the xtimer master file. However, the snif master file provides a mapping between the minor number of an interface and its name. The snif master file shipped with the DLPI subsystem has three interfaces pre-defined: one Token Ring interface, one Ethernet interface, and one FDDI interf... |

dmrb(7) -- digital media ring buffer device
|
|
The Digital Media Ring Buffer device is used to manage continuous streams of data between cooperating user processes and between user processes and the kernel. The dmrb driver is intended to be used internally by various digital media libraries and has no direct user or programmer interfaces. PPPPaaaaggggeeee 1111 |

dns(7) -- Domain Name Service
|
|
The Domain Name System (DNS) is an Internet standard name service for hostname to address translation. Queries are made from a client library (termed the resolver(4)) to a server daemon named(1M). The daemon nsd(1M) will make these calls and present the data in a filesystem namespace when the dns keyword exists in the nsswitch.conf configuration file for a domain. This man page documents the behavior of the DNS extension to the nsd daemon. The nsd daemon reads all of the nsswitch.conf configurat... |

drain(7) -- capture unimplemented link-layer protocols
|
|
The Drain protocol provides non-promiscuous capture of packets having unimplemented link-layer protocol types, i.e., packets that the operating system normally receives and drops ``down the drain''. It treats packets as datagrams containing a link-layer header followed by data. Drain uses the Raw address format, interpreting ports as link-layer type codes (in host byte order) to match against unimplemented types in received packets. Multiple sockets may bind to the same port on a network inter... |

ds(7) -- generic (user mode) SCSI driver
|
|
The ds interface provides user-mode access to the SCSI bus. It supports the programming interfaces described in dslib(3) and below. All of the ds devices support the same general interface. The program calls open, gaining exclusive use of a specified SCSI device (that is, two processes may not both have the same device open at the same time via this driver). Additionally, when the O_EXCL open flag set, exclusive use of the target will be acquired. No other SCSI driver will be able to use the tar... |
