NAME
constype - print type of Sun console
SYNOPSIS
/usr/bin/constype [ device_name ] [ -num ]
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 recog-
nized by the program.
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
