std::chrono, or something similar to implement a timeout?

[JoeStrout]

I'm looking for a way to make a long-running function time out after a certain amount of time (e.g. 10 to 100 msec). But we don't seem to have std::chrono here. And gettimeofday does not seem to update while my function is running.

Is there some other trick I can use? Some way to count display vsyncs, or set up a periodic interrupt that increments a global counter?

Ah, I'm sorry, as soon as I posted this I found the CTimer class. CTimer::GetClockTicks() does exactly what I need.
