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

 774 Some ioctl's take a pointer to a structure which contains additional
 775 pointers.
 776 These are documented here in alphabetical order.
 777
 778 .B CDROMREADAUDIO
 779 takes an input pointer
 780 .IR "const struct cdrom_read_audio\ *" .
 781 The
 782 .I buf
 783 field points to an output buffer of length
 784 .IR "nframes\ * CD_FRAMESIZE_RAW" .
 785
 786 .BR CDROMREADCOOKED ,
 787 .BR CDROMREADMODE1 ,
 788 .BR CDROMREADMODE2 ,
 789 and
 790 .B CDROMREADRAW
 791 take an input pointer
 792 .IR "const struct cdrom_msf\ *" .
 793 They use the same pointer as an output pointer to
 794 .IR "char []" .
 795 The length varies by request.
 796 For
 797 .BR CDROMREADMODE1 ,
 798 most drivers use CD_FRAMESIZE, but the Optics Storage
 799 driver uses OPT_BLOCKSIZE instead (both have the numerical value
 800 2048).
 801 .nf

 803     CDROMREADCOOKED    char [CD_FRAMESIZE]

 813 .BR EQL_GETMASTERCFG ,
 814 and
 815 .B EQL_SETMASTERCFG
 816 take a
 817 .IR "struct ifreq\ *" .
 818 The
 819 .I ifr_data
 820 field is a pointer to another structure as follows:
 821 .nf
 822
 823     EQL_ENSLAVE         const struct slaving_request *
 824     EQL_EMANCIPATE      const struct slaving_request *

 829
 830 .fi
 831 .B FDRAWCMD
 832 takes a
 833 .IR "struct floppy raw_cmd\ *" .
 834 If
 835 .I flags & FD_RAW_WRITE
 836 is nonzero, then
 837 .I data
 838 points to an input buffer of length
 839 .IR length .
 840 If
 841 .I flags & FD_RAW_READ
 842 is nonzero, then
 843 .I data
 844 points to an output buffer of length
 845 .IR length .
 846
 847 .B GIO_FONTX
 848 and
 849 .B PIO_FONTX
 850 take a
 851 .I struct console_font_desc\ *
 852 or a
 853 .IR "const struct console_font_desc\ *" ,
 854 respectively.
 855 .I chardata
 856 points to a buffer of
 857 .IR "char [charcount]" .
 858 This is an output buffer for
 859 .B GIO_FONTX
 860 and an input buffer for
 861 .BR PIO_FONTX .
 862
 863 .B GIO_UNIMAP
 864 and
 865 .B PIO_UNIMAP
 866 take a
 867 .I "struct unimapdesc\ *"
 868 or a
 869 .IR "const struct unimapdesc\ *" ,
 870 respectively.
 871 .I entries
 872 points to a buffer of
 873 .IR "struct unipair [entry_ct]" .
 874 This is an output buffer for
 875 .B GIO_UNIMAP
 876 and an input buffer for
 877 .BR PIO_UNIMAP .
 878
 879 KDADDIO, KDDELIO, KDDISABIO, and KDENABIO enable or disable access to
 880 I/O ports.
 881 They are essentially alternate interfaces to 'ioperm'.
 882
 883 .B KDMAPDISP
 884 and
 885 .B KDUNMAPDISP
 886 enable or disable memory mappings or I/O port access.
 887 They are not implemented in the kernel.
 888
 889 .B SCSI_IOCTL_PROBE_HOST
 890 takes an input pointer
 891 .IR "const int\ *" ,
 892 which is a length.
 893 It uses the same pointer as an output pointer to a
 894 .I char []
 895 buffer of this length.
 896
 897 .B SIOCADDRT
 898 and
 899 .B SIOCDELRT
 900 take an input pointer whose type depends on
 901 the protocol:
 902 .nf
 903
 904     Most protocols      const struct rtentry *
 905     AX.25               const struct ax25_route *

 907
 908 .fi
 909 .B SIOCGIFCONF
 910 takes a
 911 .IR "struct ifconf\ *" .
 912 The
 913 .I ifc_buf
 914 field points to a buffer of length
 915 .I ifc_len
 916 bytes, into which the kernel writes a list of type
 917 .IR "struct ifreq []" .
 918
 919 .B SIOCSIFHWADDR
 920 takes an input pointer whose type depends on the protocol:
 921 .nf
 922
 923     Most protocols      const struct ifreq *
 924     AX.25               const char [AX25_ADDR_LEN]
 925
 926 .fi
 927 .B TIOCLINUX
 928 takes a
 929 .IR "const char\ *" .
 930 It uses this to distinguish several
 931 independent subcases.
 932 In the table below,
 933 .I N + foo
 934 means
 935 .I foo
 936 after an N-byte pad.
 937 .I struct selection
 938 is implicitly defined in
 939 .IR drivers/char/selection.c
 940 .nf
