Hi Edward,
AFAIK Status must be a pointer, because fpwaitpid will write
information into that status.
Also, you should check the return value of fpwaitpid():
0 : nothing has happened
-1: an error occurred, check fgGetErrno
other: the pid of a child where something happened
so like (pseudoco
Sorry,
come to think about it, simply return if rv is -1,
because that means there are no un-waited children left.
You should definately first fix the pcint Status issue,
because if you give an invalid argument ot waitpid, it
returns -1 and sets errno to EINVAL.
while true
rv := waitpid(-1,

Guys, I'm trying to reply to several emails at once...
Isaac Dunham:
wpa_supplicant would be the only process reading/writing the file, but
you need five commands at minimum.
Here's roughly how you'd add an open network with wpa_cli:
NETNUM=`wpa_cli add_network` || fail
wpa_cli set_network $
hmm, I do wifi connect in bash/xterm
one shot
sudo vi /etc/network/interfaces
add
source /etc/network/interfaces.d/*.cfg
if not already there
make sure /etc/network/interfaces.d folder exists
later, check what is available

Got this working! Not sure if the modprobe files helped or just removing the
xorg.conf.
In case someone else is trying to get X working with the NVIDIA download driver,

Hi,
For the last days I have been struggling to reap zombies adopted by
the frontend with only failures. I tried several methods using
wait(-1), waidpid and trapping the signal when a child dies without
ever succeeding to reap zombies. This means, I will stop and will
leave the issue open to anyon

I found that the created zombies are owned by root and the frontend
does not run with root privileges. I think, this may be the reason.
The reason why zombies are created is that we are effectively
replacing backend by what execl calls. We may be able to solve the
issue by allowing the backend to

Nope, a zombie is actually very easy to create:
- have a process parent that spawns a chil

I kept a multithreaded netman version installed on my computer so that
I would be able to connect to wifi with a couple of button clicks. All
I can say is, that it doesn't create zombies and it is well behaved.
What we should do is do away with execl which *replaces* backend
effectively killing it
Tomorrow, I will make it a point to push my multithreaded version of
netman for evaluation. You will see multithreading did not add much
complexity with the benefit of better frontend responsiveness and no
zombies lurking around.
