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



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

       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 <mec@duracef.shout.net>.  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.

       // More arguments.

       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'.

       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_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 *
