NAME
DESCRIPTION

NAME

ioctl_list − list of ioctl calls in Linux/i386 kernel

DESCRIPTION

This is Ioctl List 1.3.27, a list of ioctl calls in Linux/i386 kernel 1.3.27. It contains 421 ioctls from /usr/include/{asm,linux}/*.h. For each ioctl, I list its numerical value, its name, and its argument type.

An argument type of ’const struct foo *’ means the argument is input to the kernel. ’struct foo *’ means the kernel outputs the argument. If the kernel uses the argument for both input and output, this is marked with // I-O.

Some ioctls take more arguments or return more values than a single structure. These are marked // MORE and documented further in a separate section.

This list is incomplete. It does not include:

-- Ioctls defined internal to the kernel (’scsi_ioctl.h’).
-- Ioctls defined in modules distributed separately from the kernel.

And, of course, I may have errors and omissions.

Please e-mail changes and comments to <mec@duracef.shout.net>. I am
particularly interested in loadable modules which define their own
ioctls. If you know of such a module, tell me where I can ftp it, and
I’ll include its ioctls in my next release.

Some ioctl’s take a pointer to a structure which contains additional
pointers. These are documented here in alphabetical order.

CDROMREADAUDIO takes an input pointer ’const struct cdrom_read_audio *’.
The ’buf’ field points to an output buffer
of length ’nframes * CD_FRAMESIZE_RAW’.

CDROMREADCOOKED, CDROMREADMODE1, CDROMREADMODE2, and CDROMREADRAW take
an input pointer ’const struct cdrom_msf *’. They use the same pointer
as an output pointer to ’char []’. The length varies by request. For
CDROMREADMODE1, most drivers use ’CD_FRAMESIZE’, but the Optics Storage
driver uses ’OPT_BLOCKSIZE’ instead (both have the numerical value
2048).

CDROMREADCOOKED

char [CD_FRAMESIZE]

CDROMREADMODE1

char [CD_FRAMESIZE or OPT_BLOCKSIZE]

CDROMREADMODE2

char [CD_FRAMESIZE_RAW0]

CDROMREADRAW

char [CD_FRAMESIZE_RAW]

EQL_ENSLAVE, EQL_EMANCIPATE, EQL_GETSLAVECFG, EQL_SETSLAVECFG,
EQL_GETMASTERCFG, and EQL_SETMASTERCFG take a ’struct ifreq *’.
The ’ifr_data’ field is a pointer to another structure as follows:

EQL_ENSLAVE

const struct slaving_request *

EQL_EMANCIPATE

const struct slaving_request *

EQL_GETSLAVECFG

struct slave_config *

// I-O

EQL_SETSLAVECFG

const struct slave_config *

EQL_GETMASTERCFG

struct master_config *

EQL_SETMASTERCFG

const struct master_config *

FDRAWCMD takes a ’struct floppy raw_cmd *’. If ’flags & FD_RAW_WRITE’
is non-zero, then ’data’ points to an input buffer of length ’length’.
If ’flags & FD_RAW_READ’ is non-zero, then ’data’ points to an output
buffer of length ’length’.

GIO_FONTX and PIO_FONTX take a ’struct console_font_desc *’ or
a ’const struct console_font_desc *’, respectively. ’chardata’ points to
a buffer of ’char [charcount]’. This is an output buffer for GIO_FONTX
and an input buffer for PIO_FONTX.

GIO_UNIMAP and PIO_UNIMAP take a ’struct unimapdesc *’ or
a ’const struct unimapdesc *’, respectively. ’entries’ points to a buffer
of ’struct unipair [entry_ct]’. This is an output buffer for GIO_UNIMAP
and an input buffer for PIO_UNIMAP.

KDADDIO, KDDELIO, KDDISABIO, and KDENABIO enable or disable access to
I/O ports. They are essentially alternate interfaces to ’ioperm’.

KDMAPDISP and KDUNMAPDISP enable or disable memory mappings or I/O port
access. They are not implemented in the kernel.

SCSI_IOCTL_PROBE_HOST takes an input pointer ’const int *’, which is a
length. It uses the same pointer as an output pointer to a ’char []’
buffer of this length.

SIOCADDRT and SIOCDELRT take an input pointer whose type depends on
the protocol:

Most protocols

const struct rtentry *

AX.25

const struct ax25_route *

NET/ROM

const struct nr_route_struct *

SIOCGIFCONF takes a ’struct ifconf *’. The ’ifc_buf’ field points to a
buffer of length ’ifc_len’ bytes, into which the kernel writes a list of
type ’struct ifreq []’.

SIOCSIFHWADDR takes an input pointer whose type depends on the protocol:

Most protocols

const struct ifreq *

AX.25

const char [AX25_ADDR_LEN]

TIOCLINUX takes a ’const char *’. It uses this to distinguish several
independent sub-cases. In the table below, ’N + foo’ means ’foo’ after
an N-byte pad. ’struct selection’ is implicitly defined
in ’drivers/char/selection.c’

TIOCLINUX-2

1 + const struct selection *

TIOCLINUX-3

TIOCLINUX-4

TIOCLINUX-5
