Look for something similar, and then follow the pattern.
The option table is in src/main.c. For example:
{ "ignore-length", 0, OPT_BOOLEAN, "ignorelength", -1 },
The associated variable is in the "options" structure defined in
src/options.h. For example:
int ignore_length; /* Do we heed content-length at all? */
Also in src/main.c is the "-h" help string:
N_("\
--ignore-length ignore `Content-Length' header field.\n"),
Initialization is in src/init.c:
{ "ignorelength", &opt.ignore_length, cmd_boolean },
And then somewhere in the code, you do something according to the value
of opt.ignore_length. In this case, it's used in src/http.c.
Out of curiosity, what is the actual problem here? Is there a Web
page somewhere with links to, say, "abc.html" and "ABC.HTML", and they
actually point to the same file because the underlying file system is
case-insensitive? My Web server ("Apache/1.3.20 (OpenVMS) [...]") runs
on a case-insensitive (ODS2) file system, but (I claim) only a dope
would rely on this fact when creating the HTML. For one thing, most
(all?) Web servers can map practically any URL into any file name, so
there's no guarantee that URL's "abc.html" and "ABC.HTML" would actually
map to the same file (because, while it would be likely, you're never
sure, for example, that URL "abc.html" is mapped into file "abc.html").
And if you ever move the Web server storage to a system with a
case-sensitive file system (UNIX-like), things will break. It's just
bad design (or bad implementation).
I don't get out much, but I've never seen this problem. Who has a
Web site which is this lame? If there is one, won't it be confusing
browsers, too, so they'd be caching multiple copies of data? I'd put
more effort into getting the Web server(s) fixed than I would adding
relatively useless features to wget to work around the problem. But
it's your life.
