ntp_gettime(2)							   System Calls 						    ntp_gettime(2)

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.
