| # 18/01/2001 - Cleanups |
| # Functions prototyped as foo(void) same as foo() |
| # Stop eval'ing where we don't need to. |
| # -- huggie@earth.li |
| |
| # 27/06/2001 - Allowed whitespace after initial "/**" and |
| # allowed comments before function declarations. |
| # -- Christian Kreibich <ck@whoop.org> |
| |
| # Still to do: |
| # - add perldoc documentation |
| # - Look more closely at some of the scarier bits :) |
| |
| # 26/05/2001 - Support for separate source and object trees. |
| # Return error code. |
| # Keith Owens <kaos@ocs.com.au> |
| |
| # 23/09/2001 - Added support for typedefs, structs, enums and unions |
| # Support for Context section; can be terminated using empty line |
| # Small fixes (like spaces vs. \s in regex) |
| # -- Tim Jansen <tim@tjansen.de> |

| Usage: $0 [OPTION ...] FILE ... |
| |
| Read C language source or header FILEs, extract embedded documentation comments, |
| and print formatted documentation to standard output. |
| |
| The documentation comments are identified by "/**" opening comment mark. See |
| Documentation/kernel-doc-nano-HOWTO.txt for the documentation comment syntax. |
| |
| Output format selection (mutually exclusive): |
| -docbook Output DocBook format. |
| -html Output HTML format. |
| -html5 Output HTML5 format. |
| -list Output symbol list format. This is for use by docproc. |
| -man Output troff manual page format. This is the default. |
| -rst Output reStructuredText format. |
| -text Output plain text format. |
| |
| Output selection (mutually exclusive): |
| -export Only output documentation for symbols that have been |
| exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() |
| in any input FILE or -export-file FILE. |
| -internal Only output documentation for symbols that have NOT been |
| exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() |
| in any input FILE or -export-file FILE. |
| -function NAME Only output documentation for the given function(s) |
| or DOC: section title(s). All other functions and DOC: |
| sections are ignored. May be specified multiple times. |
| -nofunction NAME Do NOT output documentation for the given function(s); |
| only output documentation for the other functions and |
| DOC: sections. May be specified multiple times. |
| |
| Output selection modifiers: |
| -no-doc-sections Do not output DOC: sections. |
| -enable-lineno Enable output of #define LINENO lines. Only works with |
| reStructuredText format. |
| -export-file FILE Specify an additional FILE in which to look for |
| EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with |
| -export or -internal. May be specified multiple times. |
| |
| Other parameters: |
| -v Verbose output, more warnings and other information. |
| -h Print this help. |

| # format of comments. |
| # In the following table, (...)? signifies optional structure. |
| # (...)* signifies 0 or more structure elements |
| # /** |
| # * function_name(:)? (- short description)? |
| # (* @parameterx: (description of parameter x)?)* |
| # (* a blank line)? |
| # * (Description:)? (Description of function)? |
| # * (section header: (section description)? )* |
| # (*)?*/ |
| # |
| # So .. the trivial example would be: |
| # |
| # /** |
| # * my_function |
| # */ |
| # |
| # If the Description: header tag is omitted, then there must be a blank line |
| # after the last parameter specification. |
| # e.g. |
| # /** |
| # * my_function - does my stuff |
| # * @my_arg: its mine damnit |
| # * |
| # * Does my stuff explained. |
| # */ |
| # |
| # or, could also use: |
| # /** |
| # * my_function - does my stuff |
| # * @my_arg: its mine damnit |
| # * Description: Does my stuff explained. |
| # */ |
| # etc. |
| # |
| # Besides functions you can also write documentation for structs, unions, |
| # enums and typedefs. Instead of the function name you must write the name |
| # of the declaration; the struct/union/enum/typedef must always precede |
| # the name. Nesting of declarations is not supported. |
| # Use the argument mechanism to document members or constants. |
| # e.g. |
| # /** |
| # * struct my_struct - short description |
| # * @a: first member |
| # * @b: second member |
| # * |
| # * Longer description |
| # */ |
| # struct my_struct { |
| # int a; |
| # int b; |
| # /* private: */ |
| # int c; |
| # }; |
| # |
| # All descriptions can be multiline, except the short function description. |
| # |
| # For really longs structs, you can also describe arguments inside the |
| # body of the struct. |
| # eg. |
| # /** |
| # * struct my_struct - short description |
| # * @a: first member |
| # * @b: second member |
| # * |
| # * Longer description |
| # */ |
| # struct my_struct { |
| # int a; |
| # int b; |
| # /** |
| # * @c: This is longer description of C |
| # * |
| # * You can use paragraphs to describe arguments |
| # * using this method. |
| # */ |
| # int c; |
| # }; |
| # |
| # This should be use only for struct/enum members. |
| # |
| # You can also add additional sections. When documenting kernel functions you |
| # should document the "Context:" of the function, e.g. whether the functions |
| # can be called form interrupts. Unlike other sections you can end it with an |
| # empty line. |
| # A non-void function should have a "Return:" section describing the return |
| # value(s). |
| # Example-sections should contain the string EXAMPLE so that they are marked |
| # appropriately in DocBook. |
| # |
| # Example: |
| # /** |
| # * user_function - function that can only be called in user context |
| # * @a: some argument |
| # * Context: !in_interrupt() |
| # * |
| # * Some description |
| # * Example: |
| # * user_function(22); |
| # */ |
| # ... |
| # |
| # |
| # All descriptive text is further processed, scanning for the following special |
| # patterns, which are highlighted appropriately. |
| # |
| # 'funcname()' - function |
| # '$ENVVAR' - environmental variable |
| # '&struct_name' - name of a structure (up to two words including 'struct') |
| # '&struct_name.member' - name of a structure member |
| # '@parameter' - name of a parameter |
| # '%CONST' - name of a constant. |
| # '``LITERAL``' - literal string without any spaces on it. |
