special place-holders for where the extracted documentation should
go.
-- scripts/docproc.c
+- scripts/basic/docproc.c
This is a program for converting SGML template files into SGML
files. When a file is referenced it is searched for symbols
If you just want to read the ready-made books on the various
subsystems (see Documentation/DocBook/*.tmpl), just type 'make
-psdocs', or 'make pdfdocs', or 'make htmldocs', depending on your
-preference. If you would rather read a different format, you can type
-'make sgmldocs' and then use DocBook tools to convert
-Documentation/DocBook/*.sgml to a format of your choice (for example,
+psdocs', or 'make pdfdocs', or 'make htmldocs', depending on your
+preference. If you would rather read a different format, you can type
+'make sgmldocs' and then use DocBook tools to convert
+Documentation/DocBook/*.sgml to a format of your choice (for example,
'db2html ...' if 'make htmldocs' was not defined).
If you want to see man pages instead, you can do this:
/**
* function_name(:)? (- short description)?
-(* @parameterx: (description of parameter x)?)*
+(* @parameterx(space)*: (description of parameter x)?)*
(* a blank line)?
* (Description:)? (Description of function)?
* (section header: (section description)? )*
(*)?*/
-The short function description cannot be multiline, but the other
-descriptions can be (and they can contain blank lines). Avoid putting a
-spurious blank line after the function name, or else the description will
-be repeated!
+The short function description ***cannot be multiline***, but the other
+descriptions can be (and they can contain blank lines). If you continue
+that initial short description onto a second line, that second line will
+appear further down at the beginning of the description section, which is
+almost certainly not what you had in mind.
+
+Avoid putting a spurious blank line after the function name, or else the
+description will be repeated!
All descriptive text is further processed, scanning for the following special
patterns, which are highlighted appropriately.
'@parameter' - name of a parameter
'%CONST' - name of a constant.
+NOTE 1: The multi-line descriptive text you provide does *not* recognize
+line breaks, so if you try to format some text nicely, as in:
+
+ Return codes
+ 0 - cool
+ 1 - invalid arg
+ 2 - out of memory
+
+this will all run together and produce:
+
+ Return codes 0 - cool 1 - invalid arg 2 - out of memory
+
+NOTE 2: If the descriptive text you provide has lines that begin with
+some phrase followed by a colon, each of those phrases will be taken as
+a new section heading, which means you should similarly try to avoid text
+like:
+
+ Return codes:
+ 0: cool
+ 1: invalid arg
+ 2: out of memory
+
+every line of which would start a new section. Again, probably not
+what you were after.

Take a look around the source tree for examples.
+kernel-doc for structs, unions, enums, and typedefs
+---------------------------------------------------
+
+Beside 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.
+
+Inside a struct description, you can use the "private:" and "public:"
+comment tags. Structure fields that are inside a "private:" area
+are not listed in the generated output documentation.
+
+Example:
+
+/**
+ * struct my_struct - short description
+ * @a: first member
+ * @b: second member
+ *
+ * Longer description
+ */
+struct my_struct {
+ int a;
+ int b;
+/* private: */
+ int c;
+};
