That's a powerful solution. Mine was simpler for simpler needs, it broke down the wait time in time slices and used the usual SleepEx to save CPU time, in the remainder it used a stupid loop that checked the high precision timer - after all this time slice has been assigned to my thread, might as well use it.
But the problem was simpler, I just had to prevent two data packets being sent back-to-back forcing a delay, because the target device would get FUBAR if a request would arrive while it was still processing the previous one.

Yeah, hardware can be like that!

And cheap industrial systems with real time constraints but still in the "mechanical actuation" range of values  Basically horseshoes and handgrenades.
A 155mm Howitzer *is* fairly precise, after all.

As you have discovered, this is not very accurate. A better approach is to have a recurring timer that calls your callback every TBD.
If important, you would still need to call a clock API in your callback in order to determine when it was actually called, as opposed to when it was scheduled.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

Do you mean a WM_TIMER? I thought they were even less accurate.
Care to elaborate a bit?

I went to a few interviews last year while hunting around. When asked a newbie programming question, I told them, don't ask me questions you can google the answer for. I was met with silence as they reviewed their questions and realized pretty much all of them were google-able.

I start by asking newbie questions all the time, only gradually moving up to the level that's required. This is regardless of what the interviewee claims they're capable of.
You wouldn't believe how many candidates claim something insane like "it's my algorithm that actually routes all the planes across the world in real-time", then fail to solve fizzbuzz when asked to.

I actually don't ask any questions at all. I ask them to tell me about what they have done. If it is then unclear that they know what they are talking about, then I will ask some questions.

As someone who is always moving from place to place, I kinda specialise in asking stupid questions.
The difference is that it's pretty obvious that I'm not stupid, and I'm just asking about things that I don't know yet.
It's when the person asking stupid questions is actually stupid that you have a problem.

OCCAM?
"OC" == "0C" == "Cold", and "CAM" could be a term for an unknown card that I've never heard of?
