rtime(3)                                                 rtime(3)



NAME
     rtime - gets remote time

SYNOPSIS
     #include <sys/types.h>
     #include <sys/time.h>
     #include <netinet/in.h>

     int rtime(addrp, timep, timeout)
     struct sockaddr_in *addrp;
     struct timeval *timep;
     struct timeval *timeout;

DESCRIPTION
     rtime consults the Internet Time Server at the address
     pointed to by addrp and returns the remote time in the
     timeval struct pointed to by timep.  Normally, the UDP
     protocol is used when consulting the Time Server. The
     timeout parameter specifies how long the routine should wait
     before giving up when waiting for a reply.  If timeout is
     specified as NULL, however, rtime uses TCP and blocks until
     a reply is received from the time server.

     rtime returns 0 if it is successful. Otherwise, it returns
     -1 and errno is set to reflect the cause of the error.
