How can I achieve it ?
When on the command line, I do this using the program 'socat'
(net/socat in ports). I.e.
socat FILE:/var/log/messages,ignoreeof -
This gives me the same sort of behavior as 'tail -f' exce

Take a look at how the tail command does it. You can either stat the
file periodically then read the new data if you see the timestamp or
size change (portable), or use a kqueue to get notified i
Hello everyone,
I wonder if is possible to read data from a certain file without using a pipe.
Let me explain:
I have a process already writing messages to a logfile. I want to read
all written data (without neither stop nor interfere normal log
process) from another process in real time

Hello.
Is it possible to grant real-time privileges to ordinary
users (not root) under FreeBSD? I'm doing some audio
work and I'd like to give real time privileges to my user id.

Hi
I'm having a combination of linux and freebsd OSes running a reltime
system.
On linux I use the sched_setscheduler together with raised priority to get
realtime characteristics.
I see that the same system calls are implemented in freebsd can I use the
same approach or should the

Hi Anubis and Den!
Anubis, I've "translated" the questions into what I understood.
Den, do not hesitate to complain if I had it wrong.

Dude, could you rephrase that?
Its a bit hard to understand

I have a system FreeBSD 5.1-p11.
How will develop further FreeBSD?
How real time is possible to make from FreeBSD
operational system?
I know, that in FreeBSD there are expansions real time
of standard POSIX.
I have a small kernel of system due to modules, but on
how many stably such
kernel?

So does "pure GPL", as long as you make the sources available. If you
mean that you can redistribute (potentially modified) RTEMS binaries
without providing the source code, then you've effe

Does FreeBSD has any related work about it as an real time operating
system?
Where can i find information about that ??

Hi !
I am working on some modifications in the netinet code. I therefore
want as little intereferences/side affects as possible.
I would like real time conditions ... but I think thats just an illusion :)
However, I want to minimize the effects done by userland processes,

I will and will look at adding the signal semantics. If anyone sees

Curiousity strikes me:
Is there any present plans to implement the posix realtime signal queues in the
freeBSD kernel? I fear I'm not too up on this portion of developement, but
I've been looking around to see if it's implemented and it looks like it's not
the case.
I'm writing some library cod
Even though its for linux, and linux is really a different animal,
has anyone who is interested in realtime stuff looked at
http://www.rtlinux.org
they have a whack of patches against 2.0.36 and 2.2.1.
