  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 .SS "ioctl structure"
  53 .\" added two sections - aeb
  54 Ioctl command values are 32-bit constants.
  55 In principle these constants are completely arbitrary, but people have
  56 tried to build some structure into them.
  57 .LP
  58 The old Linux situation was that of mostly 16-bit constants, where the
  59 last byte is a serial number, and the preceding byte(s) give a type
  60 indicating the driver.
  61 Sometimes the major number was used: 0x03
  62 for the
  63 .B HDIO_*
  64 ioctls, 0x06 for the
  65 .B LP*
  66 ioctls.
  67 And sometimes
  68 one or more ASCII letters were used.
  69 For example,
  70 .B TCGETS
  71 has value
  72 0x00005401, with 0x54 = \(aqT\(aq indicating the terminal driver, and
  73 .B CYGETTIMEOUT
  74 has value 0x00435906, with 0x43 0x59 = \(aqC\(aq \(aqY\(aq
  75 indicating the cyclades driver.
  76 .LP
  77 Later (0.98p5) some more information was built into the number.
  78 One has 2 direction bits
  79 (00: none, 01: write, 10: read, 11: read/write)
  80 followed by 14 size bits (giving the size of the argument),
  81 followed by an 8-bit type (collecting the ioctls in groups
  82 for a common purpose or a common driver), and an 8-bit
  83 serial number.
  84 .LP
  85 The macros describing this structure live in \fI<asm/ioctl.h>\fP
  86 and are
  87 .B _IO(type,nr)
  88 and
  89 .BR "{_IOR,_IOW,_IOWR}(type,nr,size)" .
  90 They use
  91 .I sizeof(size)
  92 so that size is a
  93 misnomer here: this third argument is a data type.
  94 .LP
  95 Note that the size bits are very unreliable: in lots of cases
  96 they are wrong, either because of buggy macros using
  97 .IR sizeof(sizeof(struct)) ,
  98 or because of legacy values.
  99 .LP
 100 Thus, it seems that the new structure only gave disadvantages:
 101 it does not help in checking, but it causes varying values
 102 for the various architectures.
 103 .SH RETURN VALUE
 104 Decent ioctls return 0 on success and \-1 on error, while
 105 any output value is stored via the argument.
 106 However,
 107 quite a few ioctls in fact return an output value.
 108 This is not yet indicated below.

 758 Some ioctl's take a pointer to a structure which contains additional
 759 pointers.
 760 These are documented here in alphabetical order.
 761
 762 .B CDROMREADAUDIO
 763 takes an input pointer
 764 .IR "const struct cdrom_read_audio *" .
 765 The
 766 .I buf
 767 field points to an output buffer of length
 768 .IR "nframes * CD_FRAMESIZE_RAW" .
 769
 770 .BR CDROMREADCOOKED ,
 771 .BR CDROMREADMODE1 ,
 772 .BR CDROMREADMODE2 ,
 773 and
 774 .B CDROMREADRAW
 775 take an input pointer
 776 .IR "const struct cdrom_msf *" .
 777 They use the same pointer as an output pointer to
 778 .IR "char []" .
 779 The length varies by request.
 780 For
 781 .BR CDROMREADMODE1 ,
 782 most drivers use CD_FRAMESIZE, but the Optics Storage
 783 driver uses OPT_BLOCKSIZE instead (both have the numerical value
 784 2048).
 785 .nf
 786
 787     CDROMREADCOOKED    char [CD_FRAMESIZE]
 788     CDROMREADMODE1     char [CD_FRAMESIZE or OPT_BLOCKSIZE]
 789     CDROMREADMODE2     char [CD_FRAMESIZE_RAW0]

 797 .BR EQL_GETMASTERCFG ,
 798 and
 799 .B EQL_SETMASTERCFG
 800 take a
 801 .IR "struct ifreq *" .
 802 The
 803 .I ifr_data
 804 field is a pointer to another structure as follows:
 805 .nf
 806
 807     EQL_ENSLAVE         const struct slaving_request *
 808     EQL_EMANCIPATE      const struct slaving_request *

 813
 814 .fi
 815 .B FDRAWCMD
 816 takes a
 817 .IR "struct floppy raw_cmd *" .
 818 If
 819 .I flags & FD_RAW_WRITE
 820 is nonzero, then
 821 .I data
 822 points to an input buffer of length
 823 .IR length .
 824 If
 825 .I flags & FD_RAW_READ
 826 is nonzero, then
 827 .I data
 828 points to an output buffer of length
 829 .IR length .
 830
 831 .B GIO_FONTX
 832 and
 833 .B PIO_FONTX
 834 take a
 835 .I struct console_font_desc *
 836 or a
 837 .IR "const struct console_font_desc *" ,
 838 respectively.
 839 .I chardata
 840 points to a buffer of
 841 .IR "char [charcount]" .
 842 This is an output buffer for
 843 .B GIO_FONTX
 844 and an input buffer for
 845 .BR PIO_FONTX .
 846
 847 .B GIO_UNIMAP
 848 and
 849 .B PIO_UNIMAP
 850 take a
 851 .I struct unimapdesc *
 852 or a
 853 .IR "const struct unimapdesc *" ,
 854 respectively.
 855 .I entries
 856 points to a buffer of
 857 .IR "struct unipair [entry_ct]" .
 858 This is an output buffer for
 859 .B GIO_UNIMAP
 860 and an input buffer for
 861 .BR PIO_UNIMAP .
 862
 863 KDADDIO, KDDELIO, KDDISABIO, and KDENABIO enable or disable access to
 864 I/O ports.
 865 They are essentially alternate interfaces to 'ioperm'.
 866
 867 .B KDMAPDISP
 868 and
 869 .B KDUNMAPDISP
 870 enable or disable memory mappings or I/O port access.
 871 They are not implemented in the kernel.
 872
 873 .B SCSI_IOCTL_PROBE_HOST
 874 takes an input pointer
 875 .IR "const int *" ,
 876 which is a length.
 877 It uses the same pointer as an output pointer to a
 878 .I char []
 879 buffer of this length.
 880
 881 .B SIOCADDRT
 882 and
 883 .B SIOCDELRT
 884 take an input pointer whose type depends on
 885 the protocol:
 886 .nf
 887
 888     Most protocols      const struct rtentry *
 889     AX.25               const struct ax25_route *
 890     NET/ROM             const struct nr_route_struct *
 891
 892 .fi
 893 .B SIOCGIFCONF
 894 takes a
 895 .IR "struct ifconf *" .
 896 The
 897 .I ifc_buf
 898 field points to a buffer of length
 899 .I ifc_len
 900 bytes, into which the kernel writes a list of type
 901 .IR "struct ifreq []" .
 902
 903 .B SIOCSIFHWADDR
 904 takes an input pointer whose type depends on the protocol:
 905 .nf
 906
 907     Most protocols      const struct ifreq *
 908     AX.25               const char [AX25_ADDR_LEN]
 909
 910 .fi
 911 .B TIOCLINUX
 912 takes a
 913 .IR "const char *" .
 914 It uses this to distinguish several
 915 independent subcases.
 916 In the table below,
 917 .I N + foo
 918 means
 919 .I foo
 920 after an N-byte pad.
 921 .I struct selection
 922 is implicitly defined in
 923 .IR drivers/char/selection.c
 924 .nf
