NAME
       ntp_gettime - get local clock values

SYNOPSIS
       #include <sys/timex.h>

       int ntp_gettime(struct ntptimeval *tptr);

DESCRIPTION
       The  ntp_gettime() function reads the local clock value and dispersion,
       returning the information in tptr.

       The ntptimeval structure contains the following members:

       struct ntptimeval {
	   struct timeval   time;	/* current time (ro) */
	   int32_t	    maxerror;	/* maximum error (us) (ro) */
	   int32_t	    esterror;	/* estimated error (us) (ro) */
       };

RETURN VALUES
       Upon successful completion, ntp_gettime()  returns  the	current	 clock
       state  (see <sys/timex.h>).  Otherwise, it returns −1 and sets errno to
       indicate the error.

ERRORS
       The ntp_gettime() function will fail if:

       EFAULT	       The tptr argument points to an invalid address.

       The ntp_gettime() function will fail for 32-bit interfaces if:

       EOVERFLOW       The size of the time.tv_sec member  of  the  ntptimeval
		       structure  pointed  to  by tptr is too small to contain
		       the correct number of seconds.
