ioctl_list


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  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  <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

       //  More  arguments.   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 cdrom_read_audio *.
       The buf field points to an output buffer of length nframes *  CD_FRAME-
       SIZE_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_GET-
       MASTERCFG, 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  uni-
       pair  [entry_ct].  This is an output buffer for GIO_UNIMAP and an input
       buffer for PIO_UNIMAP.

           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 proto-

       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
