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>

45
46Read C language source or header FILEs, extract embedded documentation comments,
47and print formatted documentation to standard output.
48
49The documentation comments are identified by "/**" opening comment mark. See
50Documentation/kernel-doc-nano-HOWTO.txt for the documentation comment syntax.
51
52Output 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
61Output 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.
74
75Output 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.
82
83Other parameters:
84  -v			Verbose output, more warnings and other information.
85  -h			Print this help.

94# In the following table, (...)? signifies optional structure.
95#                         (...)* signifies 0 or more structure elements
96# /**
97#  * function_name(:)? (- short description)?
98# (* @parameterx: (description of parameter x)?)*
99# (* a blank line)?
100#  * (Description:)? (Description of function)?
101#  * (section header: (section description)? )*
102#  (*)?*/
103#
104# So .. the trivial example would be:
105#
106# /**
107#  * my_function
108#  */
109#
110# If the Description: header tag is omitted, then there must be a blank line
111# after the last parameter specification.
112# e.g.
113# /**
114#  * my_function - does my stuff
115#  * @my_arg: its mine damnit
116#  *
117#  * Does my stuff explained.
118#  */
119#
120#  or, could also use:
121# /**
122#  * my_function - does my stuff
123#  * @my_arg: its mine damnit
124#  * Description: Does my stuff explained.
125#  */
126# etc.
127#
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.
133# e.g.
134# /**
135#  * struct my_struct - short description
136#  * @a: first member
137#  * @b: second member
138#  *
139#  * Longer description
140#  */
141# struct my_struct {
142#     int a;
143#     int b;
144# /* private: */
145#     int c;
146# };
147#
148# All descriptions can be multiline, except the short function description.
149#
150# For really longs structs, you can also describe arguments inside the
151# body of the struct.
152# eg.
153# /**
154#  * struct my_struct - short description
155#  * @a: first member
156#  * @b: second member
157#  *
158#  * Longer description
159#  */
160# struct my_struct {
161#     int a;
162#     int b;
163#     /**
164#      * @c: This is longer description of C
165#      *
166#      * You can use paragraphs to describe arguments
167#      * using this method.
168#      */
169#     int c;
170# };
171#
172# This should be use only for struct/enum members.
173#
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
177# empty line.
178# A non-void function should have a "Return:" section describing the return
179# value(s).
180# Example-sections should contain the string EXAMPLE so that they are marked
181# appropriately in DocBook.
182#
183# Example:
184# /**
185#  * user_function - function that can only be called in user context
186#  * @a: some argument
187#  * Context: !in_interrupt()
188#  *
189#  * Some description
190#  * Example:
191#  *    user_function(22);
192#  */
