     rtime(3)                   DG/UX 4.30                    rtime(3)



     NAME
          rtime - get remote time

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

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

     DESCRIPTION
          The rtime function 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, the routine will instead use TCP
          and block until a reply is received from the time server.

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