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 initial powerup default.

winsize

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

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 initial powerup default.

gettype

Issue an SIOCGETTYPE command and print to standard output various parameters from the result.

displaytype

Issue an SIOCDISPLAYTYPE command and print the result in hexadecimal.

setdisplaytype

Issue an SIOCSETDISPLAYTYPE command. 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 displaytype.
