- In parameter descriptions, strip all whitespace between the parameter
name (e.g., @len) and its description so that the description is
indented uniformly in text and man page modes. Previously, spaces
or tabs (which are used for cleaner source code viewing) affected
the produced output in a negative way.
Before (man mode):
to Destination address, in user space.
from Source address, in kernel space.
n Number of bytes to copy.
After (man mode):
to Destination address, in user space.
from Source address, in kernel space.
n Number of bytes to copy.
- Fix/clarify a few function description comments.

# 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)

# 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:
|
|
# kernel-doc [ -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).
|
|
# Cannot be used together with -function
|
|
# (yes, that's 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;
|
|
# /* private: */
|
|
# int c;
|
|
# };
|
|
#
|
|
# 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);
