  27 .TH IOCTL_LIST 2 2007-12-29 "Linux" "Linux Programmer's Manual"
  28 .SH NAME
  29 ioctl_list \- list of ioctl calls in Linux/i386 kernel
  30 .SH DESCRIPTION
  31 This is Ioctl List 1.3.27, a list of ioctl calls in Linux/i386 kernel
  32 1.3.27.
  33 It contains 421 ioctls from
  34 .IR </usr/include/{asm,linux}/*.h> .
  35 For each ioctl, its numerical value, its name, and its argument
  36 type are given.
  37 .PP
  38 An argument type of
  39 .I const struct foo *
  40 means the argument is input to the kernel.
  41 .I struct foo *
  42 means the kernel outputs the argument.
  43 If the kernel uses the argument for both input and output, this is
  44 marked with \fI//\ I-O\fP.
  45 .PP
  46 Some ioctls take more arguments or return more values than a single
  47 structure.
  48 These are marked \fI//\ MORE\fP and documented further in a
  49 separate section.
  50 .PP
  51 This list is very incomplete.
  52 Please e-mail changes and comments to <mec@duracef.shout.net>.
  53 .SS "ioctl structure"
  54 .\" added two sections - aeb
  55 Ioctl command values are 32-bit constants.
  56 In principle these constants are completely arbitrary, but people have
  57 tried to build some structure into them.
  58 .LP
  59 The old Linux situation was that of mostly 16-bit constants, where the
  60 last byte is a serial number, and the preceding byte(s) give a type
  61 indicating the driver.
  62 Sometimes the major number was used: 0x03
  63 for the
  64 .B HDIO_*
  65 ioctls, 0x06 for the
  66 .B LP*
  67 ioctls.
  68 And sometimes
  69 one or more ASCII letters were used.
  70 For example,
  71 .B TCGETS
  72 has value
  73 0x00005401, with 0x54 = 'T' indicating the terminal driver, and
  74 .B CYGETTIMEOUT
  75 has value 0x00435906, with 0x43 0x59 = 'C' 'Y'
  76 indicating the cyclades driver.
  77 .LP
  78 Later (0.98p5) some more information was built into the number.
  79 One has 2 direction bits
  80 (00: none, 01: write, 10: read, 11: read/write)
  81 followed by 14 size bits (giving the size of the argument),
  82 followed by an 8-bit type (collecting the ioctls in groups
  83 for a common purpose or a common driver), and an 8-bit
  84 serial number.
  85 .LP
  86 The macros describing this structure live in \fI<asm/ioctl.h>\fP
  87 and are
  88 .B _IO(type,nr)
  89 and
  90 .BR "{_IOR,_IOW,_IOWR}(type,nr,size)" .
  91 They use
  92 .I sizeof(size)
  93 so that size is a
  94 misnomer here: this third parameter is a data type.
  95 .LP
  96 Note that the size bits are very unreliable: in lots of cases
  97 they are wrong, either because of buggy macros using
  98 .IR sizeof(sizeof(struct)) ,
  99 or because of legacy values.
 100 .LP
 101 Thus, it seems that the new structure only gave disadvantages:
 102 it does not help in checking, but it causes varying values
 103 for the various architectures.
 104 .SH "RETURN VALUE"
 105 Decent ioctls return 0 on success and \-1 on error, while
 106 any output value is stored via the argument.
 107 However,
 108 quite a few ioctls in fact return an output value.
 109 This is not yet indicated below.

 675 Some ioctl's take a pointer to a structure which contains additional
 676 pointers.  These are documented here in alphabetical order.
 677
 678 .B CDROMREADAUDIO
 679 takes an input pointer
 680 .IR "const struct cdrom_read_audio *" .
 681 The
 682 .I buf
 683 field points to an output buffer of length
 684 .IR "nframes * CD_FRAMESIZE_RAW" .
 685
 686 .BR CDROMREADCOOKED ,
 687 .BR CDROMREADMODE1 ,
 688 .BR CDROMREADMODE2 ,
 689 and
 690 .B CDROMREADRAW
 691 take an input pointer
 692 .IR "const struct cdrom_msf *" .
 693 They use the same pointer as an output pointer to
 694 .IR "char []" .
 695 The length varies by request.
 696 For
 697 .BR CDROMREADMODE1 ,
 698 most drivers use 'CD_FRAMESIZE', but the Optics Storage
 699 driver uses 'OPT_BLOCKSIZE' instead (both have the numerical value
 700 2048).

 713 .BR EQL_GETMASTERCFG ,
 714 and
 715 .B EQL_SETMASTERCFG
 716 take a
 717 .IR "struct ifreq *" .
 718 The
 719 .I ifr_data
 720 field is a pointer to another structure as follows:
 721 .nf
 722
 723     EQL_ENSLAVE         const struct slaving_request *
 724     EQL_EMANCIPATE      const struct slaving_request *

 729
 730 .fi
 731 .B FDRAWCMD
 732 takes a
 733 .IR "struct floppy raw_cmd *" .
 734 If
 735 .I flags & FD_RAW_WRITE
 736 is non-zero, then
 737 .I data
 738 points to an input buffer of length
 739 .IR length .
 740 If
 741 .I flags & FD_RAW_READ
 742 is non-zero, then
 743 .I data
 744 points to an output buffer of length
 745 .IR length .
 746
 747 .B GIO_FONTX
 748 and
 749 .B PIO_FONTX
 750 take a
 751 .I struct console_font_desc *
 752 or a
 753 .IR "const struct console_font_desc *" ,
 754 respectively.
 755 .I chardata
 756 points to a buffer of
 757 .IR "char [charcount]" .
 758 This is an output buffer for
 759 .B GIO_FONTX
 760 and an input buffer for
 761 .BR PIO_FONTX .
 762
 763 .B GIO_UNIMAP
 764 and
 765 .B PIO_UNIMAP
 766 take a
 767 .I struct unimapdesc *
 768 or a
 769 .IR "const struct unimapdesc *" ,
 770 respectively.
 771 .I entries
 772 points to a buffer of
 773 .IR "struct unipair [entry_ct]" .
 774 This is an output buffer for
 775 .B GIO_UNIMAP
 776 and an input buffer for
 777 .BR PIO_UNIMAP .
 778
 779 KDADDIO, KDDELIO, KDDISABIO, and KDENABIO enable or disable access to
 780 I/O ports.
 781 They are essentially alternate interfaces to 'ioperm'.
 782
 783 .B KDMAPDISP
 784 and
 785 .B KDUNMAPDISP
 786 enable or disable memory mappings or I/O port access.
 787 They are not implemented in the kernel.
 788
 789 .B SCSI_IOCTL_PROBE_HOST
 790 takes an input pointer
 791 .IR "const int *" ,
 792 which is a length.
 793 It uses the same pointer as an output pointer to a
 794 .I char []
 795 buffer of this length.
 796
 797 .B SIOCADDRT
 798 and
 799 .B SIOCDELRT
 800 take an input pointer whose type depends on
 801 the protocol:
 802 .nf
 803
 804     Most protocols      const struct rtentry *
 805     AX.25               const struct ax25_route *
 806     NET/ROM             const struct nr_route_struct *
 807
 808 .fi
 809 .B SIOCGIFCONF
 810 takes a
 811 .IR "struct ifconf *" .
 812 The
 813 .I ifc_buf
 814 field points to a buffer of length
 815 .I ifc_len
 816 bytes, into which the kernel writes a list of type
 817 .IR "struct ifreq []" .
 818
 819 .B SIOCSIFHWADDR
 820 takes an input pointer whose type depends on the protocol:
 821 .nf
 822
 823     Most protocols      const struct ifreq *
 824     AX.25               const char [AX25_ADDR_LEN]
 825
 826 .fi
 827 .B TIOCLINUX
 828 takes a
 829 .IR "const char *" .
 830 It uses this to distinguish several
 831 independent sub-cases.
 832 In the table below,
 833 .I N + foo
 834 means
 835 .I foo
 836 after an N-byte pad.
 837 .I struct selection
 838 is implicitly defined in
 839 .IR drivers/char/selection.c
 840 .nf
