udp(7) -- Internet User Datagram Protocol
|
|
UDP is a simple, unreliable datagram protocol which is used to support the SOCK_DGRAM abstraction for the Internet protocol family. UDP sockets are connectionless, and are normally used with the sendto and recvfrom calls, though the connect(2) call may also be used to fix the destination for future packets (in which case the recv(2) or rea or write(2) system calls may be used). UDP address formats are identical to those used by TCP. In particular UDP provides a port identifier in addition to the... |

unix(7) -- UNIX-domain protocol family
|
|
The UNIX-domain protocol family is a collection of protocols that provides local (on-machine) interprocess communication through the normal socket(2) mechanisms. The UNIX-domain family supports the SOCK_STREAM and SOCK_DGRAM socket types and uses filesystem pathnames for addressing. |

usb(7) -- Irix USB subsystem
|
|
The SGI USB implemtation is a partial implementation, intended to provide support for selected keyboards and mice (see usbinput(7)) for Onyx3. Currently there is no administrative command for individual device control, and there is no support for devices other than keyboard/mouse. Likewise, the usb infrastructure provides no published api for the implentation of new usb drivers. Only controllers conforming to the OpenHCI spec are supported.... |

usbinput(7) -- Onyx3 usb keyboard and mouse input
|
|
In order to minimize changes to application code, the usb keyboard and mouse driver convert usb usage codes to ps2 scan code sequences at the /dev/input[N]/keyboard devices. Likewise ps2 mouse codes are generated at /dev/input[N]/mouse. The entry points /dev/input/keyboard and /dev/input/mouse will always exist. If there is no corresponding physical device (ie. no keyboard and/or mouse with device id 0), the device will operate similar to /dev/null. If an application has the device open in this ... |

usema(7) -- software semaphore driver
|
|
The usema driver is intended to be used only by the standard library spinlock and semaphore routines. Client programs should use these routines, rather than using usema directly. |

usrdma(7) -- User-Level DMA engine support interface.
|
|
The special files associated with the user-level DMA engine support interface provide access to DMA engines via the library udmalib(3X). These files should not be accessed directly by a user. Currently, the only DMA engine supported is under VME on the Challenge/Onyx series. However, as more DMA engines become available for VME and other busses on other platforms, access will be provided through this interface.... |

vino(7) -- on-board video input system for Indy
|
|
VINO supports frame(field) capture that is decimated in both the X and Y directions. Decimation of sizes 1/2th, 1/3rd, 1/4th, 1/5th, 1/6th, 1/7th and 1/8th are supported, though the color quality suffers at the smaller ranges. To compensate for this limitation, the system software initiates a decimation conversion for values 1/4th, 1/6th and 1/8th by doing the first half of the decimation in hardware and the second half of the decimation in software. This affects the software overhead required f... |

xlv(7) -- logical volume disk driver
|
|
XLV devices provide access to disk storage as logical volumes. A logical volume is an object that behaves like a disk partition, but its storage can span several physical disk devices. Using XLV, you can concatenate disks together to create larger logical volumes, stripe data across disks to create logical volumes with greater throughput, and plex (or mirror) disks for reliability. In addition, XLV enables you to change the configuration of volumes while the volume is actively being used as a fi... |
