Description

CONSTYPE(1)                 General Commands Manual                CONSTYPE(1)



NAME
       constype - print type of Sun console

SYNOPSIS
       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
