Sorry! It should be usleep() used in user space!

Best Regards,

run on the board. But, my "nsleep()" is not exactly. So, I want to
realize the timer mechanism of Linux used.

(1) which timer is used for nsleep?

I have not the slightest idea. I don't know of any  standard  funtion
with that name - neither in user space nor in kernel code.

Perhaps he means nanosleep().

Perhaps. But then the definition of nanosleep() says that it will cause
a delay of "at least the time specified in *req", i. e. the upper bound
is not even specified. But the OP seemed to assume a strict timing, so
maybe it was yet another function.
