16 # w.o. 03-11-2000: added the '-filelist' option.
18 # 18/01/2001 - Cleanups
19 # Functions prototyped as foo(void) same as foo()
20 # Stop eval'ing where we don't need to.
23 # 27/06/2001 - Allowed whitespace after initial "/**" and
24 # allowed comments before function declarations.
25 # -- Christian Kreibich <ck@whoop.org>
28 # - add perldoc documentation
29 # - Look more closely at some of the scarier bits :)
31 # 26/05/2001 - Support for separate source and object trees.
33 # Keith Owens <kaos@ocs.com.au>
35 # 23/09/2001 - Added support for typedefs, structs, enums and unions
36 # Support for Context section; can be terminated using empty line
37 # Small fixes (like spaces vs. \s in regex)
38 # -- Tim Jansen <tim@tjansen.de>
42 # This will read a 'c' file and scan for embedded comments in the
43 # style of gnome comments (+minor extensions - see below).
46 # Note: This only supports 'c'.
49 # kernel-doc [ -docbook | -html | -text | -man ] [ -no-doc-sections ]
50 # [ -function funcname [ -function funcname ...] ] c file(s)s > outputfile
52 # [ -nofunction funcname [ -function funcname ...] ] c file(s)s > outputfile
54 # Set output format using one of -docbook -html -text or -man. Default is man.
57 # Do not output DOC: sections
60 # If set, then only generate documentation for the given function(s) or
61 # DOC: section titles. All other functions and DOC: sections are ignored.
63 # -nofunction funcname
64 # If set, then only generate documentation for the other function(s)/DOC:
65 # sections. Cannot be used together with -function (yes, that's a bug --
66 # perl hackers can fix it 8))
68 # c files - list of 'c' files to process
70 # All output goes to stdout, with errors to stderr.
74 # In the following table, (...)? signifies optional structure.
75 # (...)* signifies 0 or more structure elements
77 # * function_name(:)? (- short description)?
78 # (* @parameterx: (description of parameter x)?)*
80 # * (Description:)? (Description of function)?
81 # * (section header: (section description)? )*
84 # So .. the trivial example would be:
90 # If the Description: header tag is omitted, then there must be a blank line
91 # after the last parameter specification.
94 # * my_function - does my stuff
95 # * @my_arg: its mine damnit
97 # * Does my stuff explained.
100 # or, could also use:
102 # * my_function - does my stuff
103 # * @my_arg: its mine damnit
104 # * Description: Does my stuff explained.
108 # Beside functions you can also write documentation for structs, unions,
109 # enums and typedefs. Instead of the function name you must write the name
110 # of the declaration; the struct/union/enum/typedef must always precede
111 # the name. Nesting of declarations is not supported.
112 # Use the argument mechanism to document members or constants.
115 # * struct my_struct - short description
117 # * @b: second member
119 # * Longer description
128 # All descriptions can be multiline, except the short function description.
130 # You can also add additional sections. When documenting kernel functions you
131 # should document the "Context:" of the function, e.g. whether the functions
132 # can be called form interrupts. Unlike other sections you can end it with an
134 # Example-sections should contain the string EXAMPLE so that they are marked
135 # appropriately in DocBook.
139 # * user_function - function that can only be called in user context
140 # * @a: some argument
141 # * Context: !in_interrupt()
145 # * user_function(22);
150 # All descriptive text is further processed, scanning for the following special
151 # patterns, which are highlighted appropriately.
153 # 'funcname()' - function
154 # '$ENVVAR' - environmental variable
155 # '&struct_name' - name of a structure (up to two words including 'struct')
