RTIME(3)		 BSD Library Functions Manual		      RTIME(3)

NAME
     rtime — get remote time

LIBRARY
     Standard C Library (libc, -lc)

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

     int
     rtime(struct sockaddr_in *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 argument 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.

RETURN VALUES
     The rtime() function returns the value 0 if successful; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.
