Without TCP, you have to implement your own version of
retry and ack (equivalent to negotiating a window size
of 1), and so you have to redo what's already there.
Would be nice to have a reliable channel but in our
experience not having this was not a big deal. The gdb
serial protocol is

As you can see from my log there was no library explicitly linked with
libc and no -lc command line option, but resulting executable ended up
with libc recorded right before libc_r. Any clues?

Btw, regarding the volatile thing:
If I do
extern volatile struct timecounter *timecounter;
microtime()
{
struct timecounter *tc;

The compiler complains about loosing the volatile thing.

Of course you do, it is just that the bytes are in random order.

On a totally unrelated subject to my sio.c message, I have a second problem.

Hrm, I was planning on investigating the RT capabilities of fbsd after I got
myself a decent timer mechanism. I was hoping they would be enough to get
close to RT. I have an SMP system I can use, so 1 CPU can be dedicated to
the task.
I doubt even an SMP system would help.

Any comments, suggestions, swears concerning adding a new function,
strndup(), to libc?
Many very good programmers I know carry around a library of
useful functions (and usually don't bother about inclusion in
libc). So I would suggest first you should keep this
function in your own library
From the top level page I read hotmail handles 550,000 change
requests a day. Later in the article they say they have a
5000 server farm. That translates to 110 change requests a
day on average per server. If the peak rate is 10 times the
average, that is still only about 1100
Though, a lack of good Unicode support on FreeBSD seems like
a legitimate enough reason for the move.
Yes, it would, if it were true, see /usr/ports/devel/libunicode.
One port does not make good support. For that FreeBDS has to
have native unicode support.
In order to determine if they
