cyg_clock_get_systime_res — Obtain the resolution of the system clock
Cyg_ErrNo cyg_clock_get_systime_res(struct timespec *ts
This function can be called to obtain the resolution of the system
clock. The resolution is expressed as the time difference (quantum)
corresponding to the smallest increment the clock may make, in
nanoseconds, and returned in the struct
timespec pointed to by
Due to rounding errors in calculations, and the possibly of a fine

is enabled), it is not guaranteed that the difference between two
sequential reads of system time will never be smaller than the
resolution returned here.
This function returns a standard error code, as defined in
ENOERR on success.
