NAME
ioctllist - 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 . 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 sepa‐ rate section. This list is very incomplete. ioctl structure
Ioctl command values are 32-bit constants. In principle these con‐ stants 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
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. // Main table.

Some ioctl's take a pointer to a structure which contains additional pointers. These are documented here in alphabeti‐ cal order. CDROMREADAUDIO takes an input pointer const struct cdromreadaudio *. The buf field points to an output buffer of length nframes * CDFRAME‐ SIZERAW. CDROMREADCOOKED, CDROMREADMODE1, CDROMREADMODE2, and CDROMREADRAW take an input pointer const struct cdrommsf *. They use the same pointer as an output pointer to char []. The length varies by request. For CDROMREADMODE1, most drivers use CDFRAMESIZE, but the Optics Storage driver uses OPTBLOCKSIZE instead (both have the numerical value 2048). CDROMREADCOOKED char [CDFRAMESIZE] CDROMREADMODE1 char [CDFRAMESIZE or OPTBLOCKSIZE] CDROMREADMODE2 char [CDFRAMESIZERAW0] CDROMREADRAW char [CDFRAMESIZERAW] EQLENSLAVE, EQLEMANCIPATE, EQLGETSLAVECFG, EQLSETSLAVECFG, EQLGET‐ MASTERCFG, and EQLSETMASTERCFG take a struct ifreq *. The ifrdata field is a pointer to another structure as follows: EQLENSLAVE const struct slavingrequest * EQLEMANCIPATE const struct slavingrequest * EQLGETSLAVECFG struct slaveconfig * // I-O EQLSETSLAVECFG const struct slaveconfig * EQLGETMASTERCFG struct masterconfig * EQLSETMASTERCFG const struct masterconfig * FDRAWCMD takes a struct floppy rawcmd *. If flags & FDRAWWRITE is nonzero, then data points to an input buffer of length length. If flags & FDRAWREAD is nonzero, then data points to an output buffer of length length. GIOFONTX and PIOFONTX take a struct consolefontdesc * or a const struct consolefontdesc *, respectively. chardata points to a buffer of char [charcount]. This is an output buffer for GIOFONTX and an input buffer for PIOFONTX. GIOUNIMAP and PIOUNIMAP take a struct unimapdesc * or a const struct unimapdesc *, respectively. entries points to a buffer of struct uni‐ pair [entryct]. This is an output buffer for GIOUNIMAP and an input buffer for PIOUNIMAP. 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. SCSIIOCTLPROBEHOST 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 ax25route * NET/ROM const struct nrroutestruct * SIOCGIFCONF takes a struct ifconf *. The ifcbuf field points to a buffer of length ifclen bytes, into which the kernel writes a list of type struct ifreq []. SIOCSIFHWADDR takes an input pointer whose type depends on the proto‐ col: Most protocols const struct ifreq * AX.25 const char [AX25ADDRLEN] 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 driv‐ ers/char/selection.c
