15 # w.o. 03-11-2000: added the '-filelist' option.
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>
41 # This will read a 'c' file and scan for embedded comments in the
42 # style of gnome comments (+minor extensions - see below).
45 # Note: This only supports 'c'.
48 # kernel-doc [ -docbook | -html | -text | -man ]
49 # [ -function funcname [ -function funcname ...] ] c file(s)s > outputfile
51 # [ -nofunction funcname [ -function funcname ...] ] c file(s)s > outputfile
53 # Set output format using one of -docbook -html -text or -man. Default is man.
56 # If set, then only generate documentation for the given function(s). All
57 # other functions are ignored.
59 # -nofunction funcname
60 # If set, then only generate documentation for the other function(s).
61 # Cannot be used together with -function
62 # (yes, that's a bug -- perl hackers can fix it 8))
64 # c files - list of 'c' files to process
66 # All output goes to stdout, with errors to stderr.
70 # In the following table, (...)? signifies optional structure.
71 # (...)* signifies 0 or more structure elements
73 # * function_name(:)? (- short description)?
74 # (* @parameterx: (description of parameter x)?)*
76 # * (Description:)? (Description of function)?
77 # * (section header: (section description)? )*
80 # So .. the trivial example would be:
86 # If the Description: header tag is omitted, then there must be a blank line
87 # after the last parameter specification.
90 # * my_function - does my stuff
91 # * @my_arg: its mine damnit
93 # * Does my stuff explained.
98 # * my_function - does my stuff
99 # * @my_arg: its mine damnit
100 # * Description: Does my stuff explained.
104 # Beside functions you can also write documentation for structs, unions,
105 # enums and typedefs. Instead of the function name you must write the name
106 # of the declaration; the struct/union/enum/typedef must always precede
107 # the name. Nesting of declarations is not supported.
108 # Use the argument mechanism to document members or constants.
111 # * struct my_struct - short description
113 # * @b: second member
115 # * Longer description
124 # All descriptions can be multiline, except the short function description.
126 # You can also add additional sections. When documenting kernel functions you
127 # should document the "Context:" of the function, e.g. whether the functions
128 # can be called form interrupts. Unlike other sections you can end it with an
130 # Example-sections should contain the string EXAMPLE so that they are marked
131 # appropriately in DocBook.
135 # * user_function - function that can only be called in user context
136 # * @a: some argument
137 # * Context: !in_interrupt()
141 # * user_function(22);
146 # All descriptive text is further processed, scanning for the following special
147 # patterns, which are highlighted appropriately.
149 # 'funcname()' - function
150 # '$ENVVAR' - environmental variable
151 # '&struct_name' - name of a structure (up to two words including 'struct')
