NAME
rtime — get remote time
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.
AVAILABILITY
The rtime() function is part of libtirpc.
