I did not find any nanotime function in <time.h>

I know only one nanotime functions on Mac OS X, the one declared in 
Kernel Headers (Kernel.framework/Headers/sys/time.h) and it can be 
call only from the kernel.

If you need an accurate time function (in user space), have a look at 
mach_absolute_time() (http://developer.apple.com/qa/qa2004/qa1398.html).
