26 # Certain portions of the mkerrcodes2.awk source text are designed to be
27 # copied (in certain cases, depending on the input) into the output of
28 # mkerrcodes2.awk. We call these the "data" portions. The rest of the

41 # data portions.) If your modification has such potential, you must delete

44 # This script outputs a source file that does define the following
47 # static const char msgstr[];
48 # A string containing all messages in the list.
50 # static const int msgidx[];
51 # A list of index numbers, one for each message, that points to the
52 # beginning of the string in msgstr.
55 # A macro that maps code numbers to idx numbers. If a DEFAULT MESSAGE
56 # is provided (see below), its index will be returned for unknown codes.
57 # Otherwise -1 is returned for codes that do not appear in the list.
58 # You can lookup the message with code CODE with:
59 # msgstr + msgidx[msgidxof (code)].
61 # The input file has the following format:
62 # CODE1 MESSAGE1 (Code number, <tab>, message string)
63 # CODE2 MESSAGE2 (Code number, <tab>, message string)
65 # CODEn MESSAGEn (Code number, <tab>, message string)
66 # DEFAULT MESSAGE (<tab>, fall-back message string)
68 # Comments (starting with # and ending at the end of the line) are removed,
69 # as is trailing whitespace. The last line is optional; if no DEFAULT
70 # MESSAGE is given, msgidxof will return the number -1 for unknown
74 # msg holds the number of messages.
