# This script scans the whole source code for symbols of the form
|
|
# 'xxx(yyy' where:
|
|
# xxx is either DECLARE_DEBUG_CHANNEL or DEFAULT_DEBUG_CHANNEL
|
|
# yyy is a C identifier
|
|
# It outputs on the standard output a sorted list of the
|
|
# yyy identifiers found in the .c files.
|
|
# Each identifier is reported once. Header files are not scanned.
|
|
#
|
|
# The script can be given an argument that specifies the files to be
|
|
# searched according to the following scheme:
|
|
# - if the argument does not contain a slash (/), the script
|
|
# will search the tree rooted in the current directory for
|
|
# files that match that description. You can also pass
|
|
# wildcard arguments, but remember to quote them to prevent
|
|
# expansion by the shell
|
|
# - if the argument does contain a slash, only that file is
|
|
# searched
|
|
# - if no argument is given, the argument defaults to "*.c"
|
|
# that is, all C files are searched.
|
|
# - if more than one argument is given, only the listed files are
|
|
# searched. Note that in this case, the script will not
|
|
# attempt to find them in some subdirectories, but rather
|
|
# it will try to open them in the current directory.
|
|
# Thus, if you want to disable the automatic searching when the file
|
|
# name does not contain a /, either prefix the filename with ./
|
|
# or add /dev/null as another argument.
