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 = 'T' indicating the terminal driver, and
CYGETTIMEOUT has value 0x00435906, with 0x43 0x59 = 'C' 'Y'
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'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 '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 *
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
This list does not include ioctls in the range
SIOCDEVPRIVATE and SIOCPROTOPRIVATE.
