17 # 18/01/2001 - Cleanups
18 # Functions prototyped as foo(void) same as foo()
19 # Stop eval'ing where we don't need to.
22 # 27/06/2001 - Allowed whitespace after initial "/**" and
23 # allowed comments before function declarations.
24 # -- Christian Kreibich <ck@whoop.org>
27 # - add perldoc documentation
28 # - Look more closely at some of the scarier bits :)
30 # 26/05/2001 - Support for separate source and object trees.
32 # Keith Owens <kaos@ocs.com.au>
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>
39 # 25/07/2012 - Added support for HTML5
40 # -- Dan Luedtke <mail@danrl.de>

44 Usage: $0 [OPTION ...] FILE ...
46 Read C language source or header FILEs, extract embedded documentation comments,
47 and print formatted documentation to standard output.
49 The documentation comments are identified by "/**" opening comment mark. See
50 Documentation/kernel-doc-nano-HOWTO.txt for the documentation comment syntax.
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.
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 any input FILE or -export-file FILE.
65 -internal Only output documentation for symbols that have NOT been
66 exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()
67 in any input FILE or -export-file 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.
75 Output selection modifiers:
76 -no-doc-sections Do not output DOC: sections.
77 -enable-lineno Enable output of #define LINENO lines. Only works with
78 reStructuredText format.
79 -export-file FILE Specify an additional FILE in which to look for
80 EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with
81 -export or -internal. May be specified multiple times.
84 -v Verbose output, more warnings and other information.
94 # In the following table, (...)? signifies optional structure.
95 # (...)* signifies 0 or more structure elements
97 # * function_name(:)? (- short description)?
98 # (* @parameterx: (description of parameter x)?)*
100 # * (Description:)? (Description of function)?
101 # * (section header: (section description)? )*
104 # So .. the trivial example would be:
110 # If the Description: header tag is omitted, then there must be a blank line
111 # after the last parameter specification.
114 # * my_function - does my stuff
115 # * @my_arg: its mine damnit
117 # * Does my stuff explained.
120 # or, could also use:
122 # * my_function - does my stuff
123 # * @my_arg: its mine damnit
124 # * Description: Does my stuff explained.
128 # Besides functions you can also write documentation for structs, unions,
129 # enums and typedefs. Instead of the function name you must write the name
130 # of the declaration; the struct/union/enum/typedef must always precede
131 # the name. Nesting of declarations is not supported.
132 # Use the argument mechanism to document members or constants.
135 # * struct my_struct - short description
137 # * @b: second member
139 # * Longer description
148 # All descriptions can be multiline, except the short function description.
150 # For really longs structs, you can also describe arguments inside the
151 # body of the struct.
154 # * struct my_struct - short description
156 # * @b: second member
158 # * Longer description
164 # * @c: This is longer description of C
166 # * You can use paragraphs to describe arguments
167 # * using this method.
172 # This should be use only for struct/enum members.
174 # You can also add additional sections. When documenting kernel functions you
175 # should document the "Context:" of the function, e.g. whether the functions
176 # can be called form interrupts. Unlike other sections you can end it with an
178 # A non-void function should have a "Return:" section describing the return
180 # Example-sections should contain the string EXAMPLE so that they are marked
181 # appropriately in DocBook.
185 # * user_function - function that can only be called in user context
186 # * @a: some argument
187 # * Context: !in_interrupt()
191 # * user_function(22);
196 # All descriptive text is further processed, scanning for the following special
197 # patterns, which are highlighted appropriately.
199 # 'funcname()' - function
200 # '$ENVVAR' - environmental variable
201 # '&struct_name' - name of a structure (up to two words including 'struct')
202 # '@parameter' - name of a parameter
203 # '%CONST' - name of a constant.
