Win32 MultimediaTimer equivalent

[Serge Wenger]

Hello,

I try to port to Linux (in user-mode) an application with a MultimediaTimer.
Did somebody know the Linux equivalent?

Thanks

Serge

What's a MultimediaTimer do? OK, I have VC++ here at work... (MSDN
search) "MultimediaTimer": no topics found. Well, my MSDN library is a
little out of date. Maybe you should explain what it is you want to do,
instead of throwing out a Windows function name.

If I were you, I'd take a look at the man pages for nanosleep() and
setitimer() . Or take a look at the mplayer source code. HTH,

Sorry for the "MultimediaTimer", it is Multimedia Timer.One of the function
is timeSetEvent.What I try to do is that my callback function is called
every 5 or 10ms (with a minimum of jitter).

I will try setitimer, but did you know the jitter for a particular
processor?

Thanks

OK, that might work, but the man page for setitimer() says that the
current system timer resolution is 10ms. You'll probably have to try it
and see.

No. That's why I asked if you'd looked at the mplayer source; the
mplayer developers have had to do something similar to what you're doing
for good A/V sync. If you can look at their code and figure out what
they did, you may be able to get your application working with a minimum
of reinventing the wheel. HTH,
