sleep() [3/3]

void cosmos::time::sleep ( std::chrono::nanoseconds ns )

inline

Suspends execution of the calling thread for the given number of nanoseconds.

This takes a relative sleep duration. If the call is interrupted and automatic system call restarting is not enabled in libcosmos then continuing the sleep will be difficult, because it is unknown how much sleep duration is left.

Use ClockBase::sleep() directly using an absolute sleep time to avoid this situation.

This sleep() is based on the monotonic clock.

                                           {
        auto clock = MonotonicClock{};
        auto now = clock.now();
        clock.sleep(now + MonotonicTime{ns});
