Maximum Number of Timers?

Sorry if this is readily available somewhere, but I couldn’t find it.
What’s the maximum number of timers in a process? Any problem in using ~100?

Thanks,

I don’t think there is any per-process limit, nor I think is there
a hard system limit – just total resource consumption.

Any problem in using ~100?

From the OS point of view, I don’t think so. I hope, though, you’re
not looking at having ~100 all firing at 1-3 milli-second type
intervals…that could get a bit ugly, just in the number of pulse
you’d be enqueuing.

It seems the system limit is probably 32K timers. ~100 for a process
would not stretch that limit.

To take up a previous thread, it would be useful if these OS related
parameters & implementation specifics could be documented some place
official.
These type of questions come up all the time…
