ISTR at one point someone posting here a C-pseudocode-ish skeleton for
a well-behaved Unix daemon process. It showed all the obscure incantations
for making the forked child its own process group leader, handling the
right set of signals, etc. I was *sure* I archived this message for future
reference, but of course now that I'd like to refer to it it's nowhere to
be found...
If someone could re-post the message in question, or otherwise direct me
to a concise source of this information, I'd be much oblidged.

There is no such thing as a recursive semaphore. Semaphores are not "owned"
by any thread. Mutexes are owned and can be recursive or not.
Did you intend to say "mutex" instead of semaphore, or what exactly do you
mean by recursive.

I do not set a stack size for my threads. I just take the Linux pthreads
default, which I believe is 2MB, from a gander at the source code. What does
your pthread_create call look like.

Hmmm...well, based on a scan of the requirements, I don't see anything
xemacs shouldn't be able to handle pretty readily. Did you leave it
off of your list for some particular reason? If you were just unaware
it had all these capabilities, run, don't walk, to www.xemacs.org and
see what you think... If there are particular issues with xemacs, you
might try posting to the very active and responsive gnu.emacs.xemacs
group. I don't know how to do all the things mentioned below in
xemacs off hand, but I'm nearly certain they are all readily doable.
The only issue with xemacs would be the 'small footprint', but you're
asking a hell of a lot from a 'small footprint' program anyway...
I suspect vim can do most or all of what you want as well,
particularly gvim. Frankly I'm shocked these two [vi(m) and (x)emacs]
aren't even ON your list. They are the two favorites, generally. You
can read about and download xemacs at
http://www.xemacs.org
for all platforms.
You can get gvim for windows 98 from
http://www.davecentral.com/15679.html
and you can get massive support for that program (including linux
downloads, and uncompiled windows downloads) from
http://www.gvim.org
Anyone feel free to correct me if I'm wrong about any of this.
I can't speak to the editors that are actually ON your list, but I
think these two will suit your needs.
Note that for both of these programs, under windows, you can get
greatly improved functionality (for things like compiling within the
editor) by installing cygwin as well. It can be had at
http://sources.redhat.com/cygwin/
(Below are a couple of comments specific to (x)emacs, with which I am
most familiar...for more detailed xemacs info, post to g.e.x, as
mentioned above for more detailed vim info, repost with specific
questions and put 'vim' somewhere in the subject. This is the main
vim list, oddly enough.)

Definitely, look at picture mode. If you use FSF emacs, there is a

very straightforward. for example the M-q command auto-fills the
current paragraph, and is smart enough to maintain appropriate
placement of '>'s and '//'s and so forth, spacing and all.

8 ways from sunday.

Yes. Very. :)

Not sure what you mean. Emacs has its own browser, W3, but it cannot
actually handle java applets. Emacs can automatically run netscape or
whatever for you. Are you looking for an editor that is also a fully
functional modern browser???? Might want to reevaluate, if so...I
don't think such a thing exists...
> >12. HTML toolbar (I know I should know all the tags but I just cannot

I suspect this already exists (I don't write much HTML...), certainly
emacs has an HTML mode. I'm not a font of knowledge on this point.

see top. Mostly fine. Definitely larger than notepad, but you get
what you pay for. Vim is smaller...might require you to climb a
larger learning curve to use, though...check out my urls above.
> >14. Highlights URL and e-mail addresses and launches browser or email
> >client in a separate window when clicked
this would require a tiny bit of configuration, but emacs is quite
capable of recognizing addresses and spawning child processes. I use
emacs to read my mail (see 'gnus') anyway, so that's kind of a moot
point, but if you wanted it to spawn outlook express instead, that
shouldn't be hard to arrange...post to g.e.x for help

easy.

You won't need to bother defining templates. They're all there.
C-like languages in particular are exceedingly well covered.
Supported indent styles include gnu, k&r, stroustrup, and several
others. Defining your own is easy

absolutely.
> >2. Ability to use FTP
Yes. emacs can spawn shells, and I think it has its own ftp
services. You can open remote files directly in (x)emacs:
C-xC-f [EMAIL PROTECTED]:~/.emacs
would then prompt you for a password, and let you edit '.emacs' in
your home directory on my.servers.name. This is very powerful, but
you can read the documentation, so I'll stop there.

yes. several.

M-x compile

Emacs originally stood for something like Extensible MACroS. You bet
your shorts.

You're out of luck, but odds on you can find a friend who knows emacs,
and she's probably got a phone at her desk. :)
