NAME
     sioc - invoke SIOC ioctl functions

SYNOPSIS
     /usr/amiga/bin/sioc [function [args]]

DESCRIPTION
     sioc performs an ioctl(2) operation on its  standard  input.
     The  default  ioctl command is "SIOC", which returns success
     if the connected file is a screen device  (see  screen(7A)).
     This can be used with the if shell builtin in a shell script
     to conditionalize special treatment of amiga  screens.   The
     following values for the function argument are allowed:

     0    Issue an SIOC command.  Exit  status  indicates  return
          value.  (This function is the default if no function is
          specified)

     front
          Issue an SIOCFRONT command.

     back Issue an SIOCBACK command.

     activate
          Issue an SIOCACTIVATE command.

     getkmap
          Issue an  SIOCGETKMAP  command.   A  keymap  file  (see
          kmap(7A)) is written to the standard output.

     setkmap
          Issue an SIOCSETKMAP command.  If  an  the  name  of  a
          valid  keymap  file is given, the file is read and used
          as the argument to SIOCSETKMAP, otherwise zero is used,
          selecting the default keymap.

     setdefkmap
          Issue an SIOCSETDEFKMAP command.  If an the name  of  a
          valid  keymap  file is given, the file is read and used
          as the argument to SIOCSETDEFKMAP,  otherwise  zero  is
          used,  setting the default keymap to the inital powerup
          default.

     winsize
          Issue an SIOCWINSIZE command.  The results are  written
          to standard output in the form:

          LINES=25 COLUMNS=80
          PLINES=200 PCOLUMNS=640

     getfont
          Issue  an  SIOCGETFONT  command.   A  font  file   (see

          font(7A)) is written to the standard output.

     setfont
          Issue an SIOCSETFONT command.  If  an  the  name  of  a
          valid  font file is given, the file is read and used as
          the argument to SIOCSETFONT, otherwise  zero  is  used,
          selecting the default font.

     setdeffont
          Issue an SIOCSETDEFFONT command.  If an the name  of  a
          valid  font file is given, the file is read and used as
          the argument to SIOCSETDEFFONT, otherwise zero is used,
          setting the default font to the inital powerup default.

     gettype
          Issue an SIOCGETTYPE comand and print to standard  out-
          put various parameters from the result.

     displaytype
          Issue an SIOCDISPLAYTYPE comand and print the result in
          hexadecimal.

     setdisplaytype
          Issue an SIOCSETDISPLAYTYPE comand.  One argument  must
          be  provided  which  is either a number for an absolute
          setting of displaytype, or a number preceded by `+'  or
          `-'  to set or reset the corresponding bits of display-
          type.

     setgroup
          Issue an SIOCSETGROUP  comand.   The  argument  is  the
          numeric screen group number.

     getgroup
          Issue an SIOCGETGROUP comand.  The result is printed in
          decimal.

     setdisplayadjust
          Issue an SIOCSETDISPLAYADJUST comand.   Four  arguments
          must be provided.

     getdisplayadjust
          Issue an  SIOCGETDISPLAYADJUST  comand  and  print  the
          results.

DIAGNOSTICS
     sioc's exit status indicates the success or failure  of  the
     ioctl  call.   An appropriate message is written to standard
     error output on failure.
