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>
43 # This will read a 'c' file and scan for embedded comments in the
44 # style of gnome comments (+minor extensions - see below).
47 # Note: This only supports 'c'.
50 # kernel-doc [ -docbook | -html | -html5 | -text | -man | -list ]
51 # [ -no-doc-sections ]
52 # [ -function funcname [ -function funcname ...] ]
53 # c file(s)s > outputfile
55 # [ -nofunction funcname [ -function funcname ...] ]
56 # c file(s)s > outputfile
58 # Set output format using one of -docbook -html -html5 -text or -man.
60 # The -list format is for internal use by docproc.
63 # Do not output DOC: sections
66 # If set, then only generate documentation for the given function(s) or
67 # DOC: section titles. All other functions and DOC: sections are ignored.
69 # -nofunction funcname
70 # If set, then only generate documentation for the other function(s)/DOC:
71 # sections. Cannot be used together with -function (yes, that's a bug --
72 # perl hackers can fix it 8))
74 # c files - list of 'c' files to process
76 # All output goes to stdout, with errors to stderr.
80 # In the following table, (...)? signifies optional structure.
81 # (...)* signifies 0 or more structure elements
83 # * function_name(:)? (- short description)?
84 # (* @parameterx: (description of parameter x)?)*
86 # * (Description:)? (Description of function)?
87 # * (section header: (section description)? )*
90 # So .. the trivial example would be:
96 # If the Description: header tag is omitted, then there must be a blank line
97 # after the last parameter specification.
100 # * my_function - does my stuff
101 # * @my_arg: its mine damnit
103 # * Does my stuff explained.
106 # or, could also use:
108 # * my_function - does my stuff
109 # * @my_arg: its mine damnit
110 # * Description: Does my stuff explained.
114 # Besides functions you can also write documentation for structs, unions,
115 # enums and typedefs. Instead of the function name you must write the name
116 # of the declaration; the struct/union/enum/typedef must always precede
117 # the name. Nesting of declarations is not supported.
118 # Use the argument mechanism to document members or constants.
121 # * struct my_struct - short description
123 # * @b: second member
125 # * Longer description
134 # All descriptions can be multiline, except the short function description.
136 # You can also add additional sections. When documenting kernel functions you
137 # should document the "Context:" of the function, e.g. whether the functions
138 # can be called form interrupts. Unlike other sections you can end it with an
140 # A non-void function should have a "Return:" section describing the return
142 # Example-sections should contain the string EXAMPLE so that they are marked
143 # appropriately in DocBook.
147 # * user_function - function that can only be called in user context
148 # * @a: some argument
149 # * Context: !in_interrupt()
153 # * user_function(22);
158 # All descriptive text is further processed, scanning for the following special
159 # patterns, which are highlighted appropriately.
161 # 'funcname()' - function
162 # '$ENVVAR' - environmental variable
163 # '&struct_name' - name of a structure (up to two words including 'struct')
164 # '@parameter' - name of a parameter
