       ioctl_list - list of ioctl calls in Linux/i386 kernel

       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.  Please e-mail changes and comments to
       the address in the COLOPHON section below.

   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

       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

       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 ioctls 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

       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).


       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
       non-zero, then data points to an input buffer  of  length  length.   If
       flags  &  FD_RAW_READ is non-zero, 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.

       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

	   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

	   Most protocols      const struct ifreq *
	   AX.25	       const char [AX25_ADDR_LEN]

       TIOCLINUX takes a const char *.	It uses this  to  distinguish  several
       independent  sub-cases.	In the table below, N + foo means foo after an
       N-byte	pad.	struct	 selection   is    implicitly	 defined    in

	   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

       0x00000001   FDSETPRM		  FIBMAP
