  17 # 18/01/2001 -  Cleanups
  18 #               Functions prototyped as foo(void) same as foo()
  19 #               Stop eval'ing where we don't need to.
  20 # -- huggie@earth.li
  21
  22 # 27/06/2001 -  Allowed whitespace after initial "/**" and
  23 #               allowed comments before function declarations.
  24 # -- Christian Kreibich <ck@whoop.org>
  25
  26 # Still to do:
  27 #       - add perldoc documentation
  28 #       - Look more closely at some of the scarier bits :)
  29
  30 # 26/05/2001 -  Support for separate source and object trees.
  31 #               Return error code.
  32 #               Keith Owens <kaos@ocs.com.au>
  33
  34 # 23/09/2001 - Added support for typedefs, structs, enums and unions
  35 #              Support for Context section; can be terminated using empty line
  36 #              Small fixes (like spaces vs. \s in regex)
  37 # -- Tim Jansen <tim@tjansen.de>
  38
  39 # 25/07/2012 - Added support for HTML5
  40 # -- Dan Luedtke <mail@danrl.de>

  46 Read C language source or header FILEs, extract embedded documentation comments,
  47 and print formatted documentation to standard output.
  48
  49 The documentation comments are identified by "/**" opening comment mark. See
  50 Documentation/kernel-doc-nano-HOWTO.txt for the documentation comment syntax.
  51
  52 Output format selection (mutually exclusive):
  53   -docbook              Output DocBook format.
  54   -html                 Output HTML format.
  55   -html5                Output HTML5 format.
  56   -list                 Output symbol list format. This is for use by docproc.
  57   -man                  Output troff manual page format. This is the default.
  58   -rst                  Output reStructuredText format.
  59   -text                 Output plain text format.
  60
  61 Output selection (mutually exclusive):
  62   -export               Only output documentation for symbols that have been
  63                         exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()
  64                         in the same FILE.
  65   -internal             Only output documentation for symbols that have NOT been
  66                         exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()
  67                         in the same FILE.
  68   -function NAME        Only output documentation for the given function(s)
  69                         or DOC: section title(s). All other functions and DOC:
  70                         sections are ignored. May be specified multiple times.
  71   -nofunction NAME      Do NOT output documentation for the given function(s);
  72                         only output documentation for the other functions and
  73                         DOC: sections. May be specified multiple times.
  74
  75 Output selection modifiers:
  76   -no-doc-sections      Do not output DOC: sections.
  77
  78 Other parameters:
  79   -v                    Verbose output, more warnings and other information.

  92 #  * function_name(:)? (- short description)?
  93 # (* @parameterx: (description of parameter x)?)*
  94 # (* a blank line)?
  95 #  * (Description:)? (Description of function)?
  96 #  * (section header: (section description)? )*
  97 #  (*)?*/
  98 #
  99 # So .. the trivial example would be:
 100 #
 101 # /**
 102 #  * my_function
 103 #  */
 104 #
 105 # If the Description: header tag is omitted, then there must be a blank line
 106 # after the last parameter specification.
 107 # e.g.
 108 # /**
 109 #  * my_function - does my stuff
 110 #  * @my_arg: its mine damnit
 111 #  *
 112 #  * Does my stuff explained.
 113 #  */
 114 #
 115 #  or, could also use:
 116 # /**
 117 #  * my_function - does my stuff
 118 #  * @my_arg: its mine damnit
 119 #  * Description: Does my stuff explained.
 120 #  */
 121 # etc.
 122 #
 123 # Besides functions you can also write documentation for structs, unions,
 124 # enums and typedefs. Instead of the function name you must write the name
 125 # of the declaration;  the struct/union/enum/typedef must always precede
 126 # the name. Nesting of declarations is not supported.
 127 # Use the argument mechanism to document members or constants.
 128 # e.g.
 129 # /**
 130 #  * struct my_struct - short description
 131 #  * @a: first member
 132 #  * @b: second member
 133 #  *
 134 #  * Longer description
 135 #  */

 137 #     int a;
 138 #     int b;
 139 # /* private: */
 140 #     int c;
 141 # };
 142 #
 143 # All descriptions can be multiline, except the short function description.
 144 #
 145 # For really longs structs, you can also describe arguments inside the
 146 # body of the struct.
 147 # eg.
 148 # /**
 149 #  * struct my_struct - short description
 150 #  * @a: first member
 151 #  * @b: second member
 152 #  *
 153 #  * Longer description
 154 #  */
 155 # struct my_struct {
 156 #     int a;
 157 #     int b;
 158 #     /**
 159 #      * @c: This is longer description of C
 160 #      *
 161 #      * You can use paragraphs to describe arguments
 162 #      * using this method.
 163 #      */
 164 #     int c;
 165 # };
 166 #
 167 # This should be use only for struct/enum members.
 168 #
 169 # You can also add additional sections. When documenting kernel functions you
 170 # should document the "Context:" of the function, e.g. whether the functions
 171 # can be called form interrupts. Unlike other sections you can end it with an
 172 # empty line.
 173 # A non-void function should have a "Return:" section describing the return
 174 # value(s).
 175 # Example-sections should contain the string EXAMPLE so that they are marked
 176 # appropriately in DocBook.
 177 #
 178 # Example:
 179 # /**
 180 #  * user_function - function that can only be called in user context
 181 #  * @a: some argument
 182 #  * Context: !in_interrupt()
 183 #  *
 184 #  * Some description
 185 #  * Example:
 186 #  *    user_function(22);
 187 #  */
