NAME
monitorcap - Description of device driver database file format.
DESCRIPTION
The
d.mon
command and all graphics commands
access a device driver database stored in the file
$GISBASE/etc/monitorcap.
This file contains a line for each graphics monitor on the system.
Each line contains 6 fields separated by colons:
- name
- the name by which the user identifies the driver
- program
- the full pathname of the executable driver or a
pathname relative to $GISBASE
- description
- A short 4 or 5 word description of the driver.
- fifos
- full pathnames to the input and output fifos over which
the driver communicates with the libraries
- tty
- the name of the tty from which the driver must be
started, or empty if there is no such restriction
- msg
- a message to print to the user if an attempt is made to
start the driver from the wrong tty.
EXAMPLE
The following is an example of a single monitor system. The driver may
be started from any terminal and uses
/dev/fifo.a and /dev/fifo.b for
communication with application programs:
x:driver/X:graphics monitor:/dev/fifo.a \
/dev/fifo.b::any terminal
This example has 2 monitors on the system, using the same device driver.
Note that each has a different
name
field and uses a different pair of fifos.
Also, each must be started on a specific terminal:
1:driver/X:monitor 1:/dev/fifo.1a \
/dev/fifo.1b:/dev/tty8:tty8
2:driver/X:monitor 2:/dev/fifo.2a \
/dev/fifo.2b:/dev/tty10:tty10
NOTES
Each line in this file must refer to a valid driver.
No comment lines are supported. Also, no blank lines are allowed.
