ntp_gettime(2)

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.
