Hi Fons,
thanks for this tip, The functions look good and helpful. But perhaps
I'm not getting something. I made a very simple test program, no RT
thread, no special thread at all.
https://www.dropbox.com/s/ox9owa6fdd459dt/nanosleep.cpp
I tried including both time.h and ctime. The result is that the program
just returns and the wakeup time and now drift apart ever more. Does it
need a specific thread environment?
Best wishes,
Jeanette

And using
clock_nanosleep (CLOCK_MONOTONIC, TIMER_ABSTIME, &T, 0);
in a RT thread I get
Min ~ 5 us
Max ~ 105 us
Average ~ 23 us
No need for any special libraries...
Ciao,
