i'm looking for a way to:
1. start a new process (exec(), proc_open(), popen(), whatever())
2. sleep(some_secs);
3. if the process is still running, kill it.
4. otherwise, go to 1.
any ideas on this?

Howdy,
I want to know how to tell if a forked process is done.
Actually, my real question is that I want to run a shell script inside
of a python script, and after the shell script has finished running, I
want to do more stuff *condition* on the fact that the shell script
has finished running, inside the same python script.
The only way I can think of is to fork a process and then call the

Hi everybody
For a project of system programming, we need to use semaphores, but i got
some pbs...
when I compile, i get perror with sem_open("machin", O_CREAT, 0666, 0); and
perror says function not implemented ... on a sun, i get perror : Invalid
argument...
another question : what's the max number of semaphores a process can
create??

Hello,
I would like to know if posix semaphores are inter processes or just
semaphores for threads inside the same process.
I have not seen it defined in the posix specification I have found, but
I have maybe missed something.
Thanks in advance.

I have a requirement to run two separate postmasters on the one machine. It
looks like they compete for resources (semaphores) so won't run
concurrently.
I compiled twice, specifying different ports and home directories:
./configure --with-java --with-pgport=6100
--prefix=/usr/local/teprpg01
make
etc...

Hi, I'm doing an IT degree at university, and my lecturer's do not teach
m$ technologies. I was wondering if anyone could point me to the
implementation of mutex's and semaphores in .net? Or the microsoft
equivalent of them.

In Linux this is easy with 'signal' and 'kill' but how can I get one Python
process to signal another (possibly running as a service)?
All I need is a simple prod with no other data being sent and none being
returned - except that the signal was delivered.
Receiving a signal should generate an interrupt. I'm not looking for a
solution the involves polling.
Thanks

Dear forum friends,

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
