  NAME

    sxio - STREAMS XIO device

  DESCRIPTION

    If an interactive process requires asynchronous I/O (XIO) requests and
    either STREAMS or sockets, sxio provides an interface to associate a
    selectable file descriptor with all XIO devices.  A select() or a poll()
    function on the sxio file descriptor indicates that asynchronous XIO
    events have completed.  Upon such an indication, the XIO system event flag
    mask must be read to process the completed XIO events.  To clear the sxio
    file descriptor, use the read() function, using the sxio file descriptor
    until a 0 is returned.

  FILES

    /dev/sxio   STREAMS XIO device driver

  NOTES

    The data returned from sxio is a list of the event flag numbers from
    asynchronous events in the order that they occurred.
