  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 .PP
  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 .PP
  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 .PP
  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 .PP
 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 .PP
 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.
