# 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>

# This will read a 'c' file and scan for embedded comments in the
|
|
# style of gnome comments (+minor extensions - see below).
|
|
#
|
|
|
|
# Note: This only supports 'c'.
|
|
|
|
# usage:
|
|
# kerneldoc [ -docbook | -html | -text | -man ]
|
|
# [ -function funcname [ -function funcname ...] ] c file(s)s > outputfile
|
|
# or
|
|
# [ -nofunction funcname [ -function funcname ...] ] c file(s)s > outputfile
|
|
#
|
|
# Set output format using one of -docbook -html -text or -man. Default is man.
|
|
#
|
|
# -function funcname
|
|
# If set, then only generate documentation for the given function(s). All
|
|
# other functions are ignored.
|
|
#
|
|
# -nofunction funcname
|
|
# If set, then only generate documentation for the other function(s). All
|
|
# other functions are ignored. Cannot be used with -function together
|
|
# (yes thats a bug - perl hackers can fix it 8))
|
|
#
|
|
# c files - list of 'c' files to process
|
|
#
|
|
# All output goes to stdout, with errors to stderr.
|
|
|
|
#
|
|
# 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 ommitted, 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.
|
|
#
|
|
# 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.
|
|
# e.g.
|
|
# /**
|
|
# * struct my_struct - short description
|
|
# * @a: first member
|
|
# * @b: second member
|
|
# *
|
|
# * Longer description
|
|
# */
|
|
# struct my_struct {
|
|
# int a;
|
|
# int b;
|
|
# };
|
|
#
|
|
# All descriptions can be multiline, except the short function description.
|
|
#
|
|
# 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.
|
|
# 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);
|
|
# */

# patterns, which are highlighted appropriately.

|

# '&struct_name' - name of a structure (up to two words including 'struct')
