# 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

159
# patterns, which are highlighted appropriately.
