IOCTL_LIST(2)		   Linux Programmer's Manual		 IOCTL_LIST(2)

       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 /usr/include/{asm,linux}/*.h.  For
       each  ioctl,  I	list  its  numerical value, its	name, and its argument

       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 incomplete.	 It does not include:

	   -- Ioctls defined internal to the kernel ('scsi_ioctl.h').
	   -- Ioctls defined in	modules	distributed separately from the	kernel.

       And, of course, I may have errors and omissions.

       Please e-mail changes and comments to <>.  I am
       particularly interested in loadable modules which define	their own
       ioctls.	If you know of such a module, tell me where I can ftp it, and
       I'll include its	ioctls in my next release.

       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'.

       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


       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 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 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 *

       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 sub-cases.  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 *
