19 | # 18/01/2001 - Cleanups |
20 | # Functions prototyped as foo(void) same as foo() | |
21 | # Stop eval'ing where we don't need to. | |
22 | # -- huggie@earth.li | |
23 | ||
24 | # 27/06/2001 - Allowed whitespace after initial "/**" and | |
25 | # allowed comments before function declarations. | |
26 | # -- Christian Kreibich <ck@whoop.org> | |
27 | ||
28 | # Still to do: | |
29 | # - add perldoc documentation | |
30 | # - Look more closely at some of the scarier bits :) | |
31 | ||
32 | # 26/05/2001 - Support for separate source and object trees. | |
33 | # Return error code. | |
34 | # Keith Owens <kaos@ocs.com.au> | |
35 | ||
36 | # 23/09/2001 - Added support for typedefs, structs, enums and unions | |
37 | # Support for Context section; can be terminated using empty line | |
38 | # Small fixes (like spaces vs. \s in regex) | |
39 | # -- Tim Jansen <tim@tjansen.de> | |
40 | ||
1b40c194 DL |
41 | # 25/07/2012 - Added support for HTML5 |
42 | # -- Dan Luedtke <mail@danrl.de> | |

48 | Read C language source or header FILEs, extract embedded documentation comments, | |
49 | and print formatted documentation to standard output. | |
50 | ||
51 | The documentation comments are identified by "/**" opening comment mark. See | |
857af3b7 | 52 | Documentation/doc-guide/kernel-doc.rst for the documentation comment syntax. |
fadc0b31 JN |
53 | |
54 | Output format selection (mutually exclusive): | |
fadc0b31 | 55 | -man Output troff manual page format. This is the default. |
c0d1b6ee | 56 | -rst Output reStructuredText format. |
3a025e1d | 57 | -none Do not output documentation, only warnings. |
fadc0b31 JN |
58 | |
59 | Output selection (mutually exclusive): | |
86ae2e38 JN |
60 | -export Only output documentation for symbols that have been |
61 | exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() | |
c9b2cfb3 | 62 | in any input FILE or -export-file FILE. |
86ae2e38 JN |
63 | -internal Only output documentation for symbols that have NOT been |
64 | exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() | |
c9b2cfb3 | 65 | in any input FILE or -export-file FILE. |
fadc0b31 JN |
66 | -function NAME Only output documentation for the given function(s) |
67 | or DOC: section title(s). All other functions and DOC: | |
68 | sections are ignored. May be specified multiple times. | |
69 | -nofunction NAME Do NOT output documentation for the given function(s); | |
70 | only output documentation for the other functions and | |
71 | DOC: sections. May be specified multiple times. | |
72 | ||
73 | Output selection modifiers: | |
74 | -no-doc-sections Do not output DOC: sections. | |
0b0f5f29 DV |
75 | -enable-lineno Enable output of #define LINENO lines. Only works with |
76 | reStructuredText format. | |
88c2b57d JN |
77 | -export-file FILE Specify an additional FILE in which to look for |
78 | EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with | |
79 | -export or -internal. May be specified multiple times. | |

99 | # * (section header: (section description)? )* | |
100 | # (*)?*/ | |

110 | # e.g. | |
111 | # /** | |

3c3b809e | 175 | # empty line. |
