# 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 | -gnome | -bird ]
|
|
# [ -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 -man -gnome or -bird. 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.
|

#
|
|
