CONSTYPE(__appmansuffix__)

NAME
constype - print type of Sun console

SYNOPSIS
constype [ -num ] [ device_name ]

constype -help

constype -version

DESCRIPTION
constype prints on the standard output the Sun code for the type of display that the specified device is.

If the OS and device support the VIS_GETIDENTIFIER ioctl, the value returned from the ioctl is the value printed by constype. Sample types output for these include:

SUNWffb        Sun Creator 3D (ffb) Graphics Accelerator
SUNWm64        Sun PGX8, PGX24 or PGX64 Frame Buffer
SUNWtext       Generic vgatext console for Solaris x86 graphics
                devices without specific kernel drivers

Otherwise, the older fbio identification methods are used, for which the types output include these:

bw?	Black and White, where ? is 1-4. (eg) 3-50s are bw2
cg?	Colour Graphics display, where ? is 1-6, 8, 12
gp?	Optional Graphics Processor board, where ? is 1-2
ns?	Not Sun display — where ? is A-J

This is useful in determining startup values and defaults for window systems.

The device_name argument, if given, is the device to examine. If not given, /dev/fb is used.

The -num option causes constype to follow the type keyword with the numeric value of that type, as returned by the FBIOGATTR or FBIOGTYPE ioctl and defined in <fbio.h>. This is useful if the type is not recognized by the program.

The -help option causes constype to print a usage message and exit.

The -version option causes constype to print its version and exit.

EXIT STATUS
The program exits with status 0 if it identified a known console type, 1 if the type was unknown, and 2 if the device could not be opened or another error occurred.

BUGS
Not tested on all frame buffer types
