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

 850 Some ioctl's take a pointer to a structure which contains additional
 851 pointers.
 852 These are documented here in alphabetical order.
 853 .PP
 854 .B CDROMREADAUDIO
 855 takes an input pointer
 856 .IR "const struct cdrom_read_audio\ *" .
 857 The
 858 .I buf
 859 field points to an output buffer of length
 860 .IR "nframes\ * CD_FRAMESIZE_RAW" .
 861 .PP
 862 .BR CDROMREADCOOKED ,
 863 .BR CDROMREADMODE1 ,
 864 .BR CDROMREADMODE2 ,
 865 and
 866 .B CDROMREADRAW
 867 take an input pointer
 868 .IR "const struct cdrom_msf\ *" .
 869 They use the same pointer as an output pointer to
 870 .IR "char []" .
 871 The length varies by request.
 872 For
 873 .BR CDROMREADMODE1 ,
 874 most drivers use CD_FRAMESIZE, but the Optics Storage
 875 driver uses OPT_BLOCKSIZE instead (both have the numerical value
 876 2048).

 910 If

 914 points to an input buffer of length
 915 .IR length .
 916 If

 938 .PP
 939 .B GIO_UNIMAP
 940 and

 955 KDADDIO, KDDELIO, KDDISABIO, and KDENABIO enable or disable access to
 956 I/O ports.
 957 They are essentially alternate interfaces to 'ioperm'.
 958 .PP
 959 .B KDMAPDISP
 960 and
 961 .B KDUNMAPDISP
 962 enable or disable memory mappings or I/O port access.
 963 They are not implemented in the kernel.
 964 .PP
 965 .B SCSI_IOCTL_PROBE_HOST
 966 takes an input pointer
 967 .IR "const int\ *" ,
 968 which is a length.
 969 It uses the same pointer as an output pointer to a
 970 .I char []
 971 buffer of this length.
 972 .PP
 973 .B SIOCADDRT
 974 and
 975 .B SIOCDELRT
 976 take an input pointer whose type depends on
 977 the protocol:
 978 .PP
 979 .nf
 980     Most protocols      const struct rtentry *
 981     AX.25               const struct ax25_route *
 982     NET/ROM             const struct nr_route_struct *

 984 .fi
 985 .PP
 986 .B SIOCGIFCONF
 987 takes a
 988 .IR "struct ifconf\ *" .
 989 The
 990 .I ifc_buf
 991 field points to a buffer of length
 992 .I ifc_len
 993 bytes, into which the kernel writes a list of type
 994 .IR "struct ifreq []" .
 995 .PP
 996 .B SIOCSIFHWADDR
 997 takes an input pointer whose type depends on the protocol:
 998 .PP
 999 .nf
1000     Most protocols      const struct ifreq *
1001     AX.25               const char [AX25_ADDR_LEN]
1002 .fi
1003 .PP
1004 .B TIOCLINUX
1005 takes a
1006 .IR "const char\ *" .
1007 It uses this to distinguish several
1008 independent subcases.
1009 In the table below,
1010 .I N + foo
1011 means
1012 .I foo
1013 after an N-byte pad.
1014 .I struct selection
1015 is implicitly defined in
1016 .IR drivers/char/selection.c
1017 .PP
