NAME

6       ioctl_list - list of ioctl calls in Linux/i386 kernel
7

DESCRIPTION

9       This  is  Ioctl List 1.3.27, a list of ioctl calls in Linux/i386 kernel
10       1.3.27.  It contains 421  ioctls  from  </usr/include/{asm,linux}/*.h>.
11       For  each  ioctl,  its numerical value, its name, and its argument type
12       are given.
13
14       An argument type of const struct foo * means the argument is  input  to
15       the  kernel.   struct  foo * means the kernel outputs the argument.  If
16       the kernel uses the argument for both input and output, this is  marked
17       with // I-O.
18
19       Some  ioctls  take  more  arguments or return more values than a single
20       structure.  These are marked // MORE and documented further in a  sepa‐
21       rate section.
22
23       This list is very incomplete.
24
25   ioctl structure
26       Ioctl  command  values  are  32-bit constants.  In principle these con‐
27       stants are completely arbitrary, but people have tried  to  build  some
28       structure into them.
29
30       The  old Linux situation was that of mostly 16-bit constants, where the
31       last byte is a serial number, and the preceding  byte(s)  give  a  type
32       indicating  the  driver.  Sometimes the major number was used: 0x03 for
33       the HDIO_* ioctls, 0x06 for the LP* ioctls.  And sometimes one or  more
34       ASCII  letters  were  used.   For example, TCGETS has value 0x00005401,
35       with 0x54 = 'T' indicating the terminal driver,  and  CYGETTIMEOUT  has
36       value  0x00435906,  with  0x43  0x59  = 'C' 'Y' indicating the cyclades
37       driver.
38
39       Later (0.98p5) some more information was built into  the  number.   One
40       has  2  direction  bits (00: none, 01: write, 10: read, 11: read/write)
41       followed by 14 size bits (giving the size of the argument), followed by
42       an  8-bit type (collecting the ioctls in groups for a common purpose or
43       a common driver), and an 8-bit serial number.
44
45       The macros describing this structure  live  in  <asm/ioctl.h>  and  are
46       _IO(type,nr)    and    {_IOR,_IOW,_IOWR}(type,nr,size).     They    use
47       sizeof(size) so that size is a misnomer here: this third argument is  a
48       data type.
49
50       Note  that the size bits are very unreliable: in lots of cases they are
51       wrong, either because of buggy macros using sizeof(sizeof(struct)),  or
52       because of legacy values.
53
54       Thus,  it seems that the new structure only gave disadvantages: it does
55       not help in checking, but it causes  varying  values  for  the  various
56       architectures.
57

RETURN VALUE

59       Decent  ioctls  return  0  on success and -1 on error, while any output
60       value is stored via the argument.  However, quite a few ioctls in  fact
61       return an output value.  This is not yet indicated below.

676
677       CDROMREADAUDIO  takes an input pointer const struct cdrom_read_audio *.
678       The buf field points to an output buffer of length nframes *  CD_FRAME‐
679       SIZE_RAW.
680
681       CDROMREADCOOKED,  CDROMREADMODE1, CDROMREADMODE2, and CDROMREADRAW take
682       an input pointer const struct cdrom_msf *.  They use the  same  pointer
683       as  an  output  pointer to char [].  The length varies by request.  For
684       CDROMREADMODE1, most drivers use CD_FRAMESIZE, but the  Optics  Storage
685       driver uses OPT_BLOCKSIZE instead (both have the numerical value 2048).
686
687           CDROMREADCOOKED    char [CD_FRAMESIZE]
688           CDROMREADMODE1     char [CD_FRAMESIZE or OPT_BLOCKSIZE]
689           CDROMREADMODE2     char [CD_FRAMESIZE_RAW0]
690           CDROMREADRAW       char [CD_FRAMESIZE_RAW]
691
692       EQL_ENSLAVE, EQL_EMANCIPATE, EQL_GETSLAVECFG, EQL_SETSLAVECFG, EQL_GET‐
693       MASTERCFG, and EQL_SETMASTERCFG take a struct  ifreq *.   The  ifr_data
694       field is a pointer to another structure as follows:
695
696           EQL_ENSLAVE         const struct slaving_request *
697           EQL_EMANCIPATE      const struct slaving_request *

700           EQL_GETMASTERCFG    struct master_config *
701           EQL_SETMASTERCFG    const struct master_config *
702
703       FDRAWCMD  takes  a struct floppy raw_cmd *.  If flags & FD_RAW_WRITE is
704       nonzero, then data points to an input  buffer  of  length  length.   If
705       flags & FD_RAW_READ is nonzero, then data points to an output buffer of
706       length length.
707
708       GIO_FONTX and PIO_FONTX take a struct console_font_desc *  or  a  const
709       struct  console_font_desc *, respectively.  chardata points to a buffer
710       of char [charcount].  This is an output buffer  for  GIO_FONTX  and  an
711       input buffer for PIO_FONTX.
712
713       GIO_UNIMAP  and PIO_UNIMAP take a struct unimapdesc * or a const struct
714       unimapdesc *, respectively.  entries points to a buffer of struct  uni‐
715       pair  [entry_ct].  This is an output buffer for GIO_UNIMAP and an input
716       buffer for PIO_UNIMAP.
717
718       KDADDIO, KDDELIO, KDDISABIO, and KDENABIO enable or disable  access  to
719       I/O ports.  They are essentially alternate interfaces to 'ioperm'.
720
721       KDMAPDISP and KDUNMAPDISP enable or disable memory mappings or I/O port
722       access.  They are not implemented in the kernel.
723
724       SCSI_IOCTL_PROBE_HOST takes an input pointer const int *,  which  is  a
725       length.   It  uses  the  same pointer as an output pointer to a char []
726       buffer of this length.
727
728       SIOCADDRT and SIOCDELRT take an input pointer whose type depends on the
729       protocol:
730
731           Most protocols      const struct rtentry *
732           AX.25               const struct ax25_route *
733           NET/ROM             const struct nr_route_struct *

736       SIOCGIFCONF  takes  a  struct  ifconf *.  The ifc_buf field points to a
737       buffer of length ifc_len bytes, into which the kernel writes a list  of
738       type struct ifreq [].
739
740       SIOCSIFHWADDR  takes  an input pointer whose type depends on the proto‐
741       col:

744           AX.25               const char [AX25_ADDR_LEN]
745
746       TIOCLINUX takes a const char *.  It uses this  to  distinguish  several
747       independent  subcases.   In the table below, N + foo means foo after an
748       N-byte  pad.   struct  selection  is  implicitly   defined   in   driv‐
749       ers/char/selection.c
