how to get ntp information to program level

Question

I have some machines (linux) on ntp setup. they are running some apps (c++ written) that talk to each other. I need the app A of machine A to get ntp information from machine B through app B. What is the best way to do so?

I mean some ntp information like if/in case the clocks are out of sync

Thank you.

Anything wrong with a tcp socket and just transferring the data? — dutt, Mar 11 '14 at 08:48
Sorry i mean some ntp information like if/in case the clocks are out of sync. — user3403788, Mar 11 '14 at 08:52
dutt, can I get the ntp clock/outOfSync information through tcp socket? — user3403788, Mar 11 '14 at 08:53
I would suggest simply using an NTP library or external NTP program on each machine. Trying to push NTP information through the link is only going to complicate things unless you have a good reason to do so? — Jon Cage, Mar 11 '14 at 08:55

@Jon-Cage tanx. i did not really understand it. is the libntp installed if i install ntp? or how do i get it. — user3403788, Mar 11 '14 at 09:16
i think ntp_gettime() also looks good http://www.freebsd.org/cgi/man.cgi?query=ntp_gettime — user3403788, Mar 11 '14 at 11:25

I used ntp_gettime() from sys/timex.h.
