DISPLAY(4)                      Domain/OS BSD                       DISPLAY(4)



NAME
     display - window device for display manager

DESCRIPTION
     The display device provides write-only access to users logged in to the
     Display Manager (DM).  Opening this device creates a new transcript
     window and an associated output stream.  Attempts to read from this
     device will fail.

     The contents of /sys/dm/dev_display.conf may be used to force windows to
     be created in a particular position.  This file must contain a single
     line containing a pair of coordinates defining a region.  The coordinate
     pairs must be separated by white space, as must the coordinates within
     each pair.  For example, the presence of /sys/dm/dev_display.conf
     containing

          0 0 500 200

     would force windows to be created in the upper left corner of the
     display.  If this file does not exist, the display device creates windows
     in the default positions as specified to the DM with the wdf command.

     This is the login device for the DM.  It is used by programs such as
     write(1), mesg(1) and who(1).

     See pad(4) for more information about I/O on specific DM windows.
