Appendix D
Factory Display Details
The fdisplay,fdaemon, andfdriver programs were described in chapter 6. This appendix
will provide a brieffdisplay user's manual, as well as a technical specification of thefdisplay command language and the fdriver file format.
User's Manual
The fdisplay program may be spawned from another program or started directly from the
command line prompt. It is intended that fdisplay will be run in conjunction with a driver
program via a socket connection. As a result, when thefdisplay program is launched it
must be made aware of the socket address of the host driver program. The -host command
line option followed by the host address can be used. The host address can either be in the
form ip_address:port,for a TCP socket connection, or a unix path for a unix domain
socket connection. If the -host option is not explicitly specified, then thefdisplay program
will use the setting of the FD_HOSTenvironment variable, if it has been set. The following lines are examples of how to launch the fdisplay program:
prompt% fdisplay -host garcon.mit.edu:1086
