Interval timers on Fedora

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This probably isn't a Fedora specific question so I apologize if this is the wrong forum.

Anybody know if you can set more than one interval timer in a single process?

(setitimer())

Would starting more than one interval timer in a single process confuse the signal system when delivering the SIGALRM to the receiving process?

In other words, can I have a 10 second interval timer which when times out delivers a sigalrm to one function, and in the same process have a 1 second interval timer set to give a sigalrm to another function?

I'm having trouble with a second interval timer, it doesn't seem to work, or deliver the signal to the desired function. I'm using a separate instance of struct itimerval and struct sigaction when setting up the timers. I have several books on the subject of interval timers but none say you shouldn't do this, just "Every process has its own set of timers". But they might be referring to REAL, VIRTUAL, and PROF timers, a single set of these for each process.

Opinions requested...

Thanks

Doug P
