Does the segfault happen when you run the program individually?
(outside conky)
EDIT: I can't reproduce the segfaults, something else must be happening to your conky

Sorry for the delay. Yes, I get a seg fault.

Compile it with the -g option to enable debugging, ie

gcc accuw.c -o accuw -lcurl -g

and rerun gdb to find out exactly where the segfault occurs.

Now that I see the code with a clear head (and also writing the C port of the weather.com script), I notice a few bugs myself.

As Yoda would say:

I understand not the results. Herh herh herh.

That's extremely helpful; thanks a lot.

EDIT: As a matter of fact, that explains everything, thanks again.
That part of the code searches for the pid of conky. If a single instance of conky is running, the pid is ensured to fit in a 10 char array (c[10]).
In your case, running 100 conkys or something, the return value of pidof conky is something like 12434 13535 433433 34453 23433 54333 etc.
This output could never fit in a 10 character array and therefore the segfault.

EDIT2: Confirmed: it segfaults mercilessly when more than one conkys is running. In the new version I'm currently playing with, I'll make sure that the program can pause all instances of conky.

PS: gdb kicks ass.

hahahahaha 100 conkys, no, just 10. big_smile

you may be right about gdb, but you rock!

However, it's good to know that the problem can be fixed and SUPER GOOD to know that my ability to break things actually helped. lol

I'm kidding about the breaking things - even though I do.

Thanks for the feedback man!
I'll just force popen to call kill -STOP $(pidof conky) immediately, without trying to complicate things even more in the C part.
I mean, since I cheat calling it, why not go all the way?

EDIT: If you run the program with 1 or less conkys running, you'll see that it doesn't segfault.

The 2 alone of course; in its current version, the C one will segfault with more than 1 conkys running.

Wait for it I have some neat results ... 5-6 minutes.

Sector11 · 2012-05-26 21:56:31

NOTE: May C and May B(ash)

Notice the start line:

mainstream called just before ms - they arrive at the same time.

called in reverse:

ms then mainstream - arrived at the same time again.

Then I tried:

conky -c ~/accuweather_conky_modified/mainstream.conky && conky -c ~/accuweather_conky_mod/ms.conky &

Watched mainstream come in --- yawn --- did a KFC -- instantly ms was there!

Delay because of problems with imgBox - using ImgBam - DONE!

The segfault is because of the 2 conkys.
Wait a day or two for that...

Who needs Faith? How 'bout tried, tested, and true results that go back months without any sort of evidence to contradict it? An AXIOM, if you will. 'Cause if you can find evidence to the contrary that Teo will pull some sort of miracle out of his ass, THAT would be impressive. He's literally never done anything else but do awesome. It's become an Axiom at this point. And, isn't it a famous quote now, that the definition of Insanity is repeating the same things, expecting different results?

So... Same thing here... Teo at work on something new... Axiom and the definition of Insanity considered? It will be Awesome. Teo doesn't like it when it's not. That's good enough for me.

Seriously... There are times he just... MAGICALLY pulls the solution out... often in record times!... Sometimes I worry he doesn't sleep, or he's skipping meals or something.

Oh, take your time Teo. If you rush, I'll worry you over-worked yourself again tongue Like I said SOMETIMES I think you don't sleep or skip meals. Blows my mind how much work you put into these things.
