Section (2) ioctl_list
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, its numerical value,
its name, and its argument type are given.
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. In addition, information about some ioctls
can be found in the pages listed under SEE ALSO in ioctl(2).
This list is very incomplete.
ioctl structure
Ioctl command values are 32-bit constants. In principle these constants are completely arbitrary, but people have tried to build some structure into them.
The old Linux situation was that of mostly 16-bit
constants, where the last byte is a serial number, and the
preceding byte(s) give a type indicating the driver.
Sometimes the major number was used: 0x03 for the
HDIO_*
ioctls,
0x06 for the LP*
ioctls. And sometimes one or more ASCII letters were used.
For example, TCGETS
has value
0x00005401, with 0x54 = _zsingle_quotesz_T_zsingle_quotesz_ indicating the terminal driver,
and CYGETTIMEOUT
has value
0x00435906, with 0x43 0x59 = _zsingle_quotesz_C_zsingle_quotesz_ _zsingle_quotesz_Y_zsingle_quotesz_ indicating the
cyclades driver.
Later (0.98p5) some more information was built into the number. One has 2 direction bits (00: none, 01: write, 10: read, 11: read/write) followed by 14 size bits (giving the size of the argument), followed by an 8-bit type (collecting the ioctls in groups for a common purpose or a common driver), and an 8-bit serial number.
The macros describing this structure live in
<
asm/ioctl.h
>
and are _IO(type,nr)
and
{_IOR,_IOW,_IOWR}
(
type
,
nr
,
size
)
. They use sizeof(size)
so that size
is a misnomer here: this third argument is a data type.
Note that the size bits are very unreliable: in lots of
cases they are wrong, either because of buggy macros using
sizeof(sizeof(struct))
, or
because of legacy values.
Thus, it seems that the new structure only gave disadvantages: it does not help in checking, but it causes varying values for the various architectures.
RETURN VALUE
Decent ioctls return 0 on success and −1 on error, while any output value is stored via the argument. However, quite a few ioctls in fact return an output value. This is not yet indicated below.

// More arguments. Some ioctl_zsingle_quotesz_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 nonzero, then data
points to an input
buffer of length length
. If flags & FD_RAW_READ is
nonzero, 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 _zsingle_quotesz_ioperm_zsingle_quotesz_.
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 * INET6 const struct in6_rtmsg *
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 subcases. 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 void TIOCLINUX-4 void TIOCLINUX-5 4 + const struct { long [8]; } * TIOCLINUX-6 char * TIOCLINUX-7 char * TIOCLINUX-10 1 + const char *
// Duplicate ioctls
