Hello all,

    the Sleep(1) call puts the program in a hold status for at least 1ms
(nominal...).
I am interfacing some external hardware in my program, and I need to
insert a small delay between consecutive operations. But 1ms is too
much, the overall response time becomes too sluggish. I reckoned that 50
to 100 usec would do nicely.

Is there a simple way to do that ?

A possible solution could be to use the QueryPerformanceCounter API,
then do a spin loop waiting for 100 usec to be elapsed, but of course a
spin loop is a no-no in a multitasking system like Windows.
I am open to suggestions, thanks.

Alberto
