of the realtime clock. <tt/clock_id/ has to be <tt/CLOCK_REALTIME/. If <tt/res/
is not <tt/NULL/, the resolution of the realtime clock is stored in the location
pointed to by <tt/res/. If <tt/res/ is <tt/NULL/, the clock resolution is not returned.

a multiple of <tt/res/, then the value is truncated to a multiple of <tt/res/. On
success, zero is returned. On error, -1 is returned and <tt/errno/ is set to an
error code describing the reason for the failure.
