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.
