DESCRIPTION
The
rtime ();
function
consults the Internet Time Server at the address pointed to by
Fa addrp
and returns the remote time in the
Vt timeval
struct pointed to by
Fa timep .
Normally, the
UDP
protocol is used when consulting the Time Server.
The
Fa timeout
argument specifies how long the
routine should wait before giving
up when waiting for a reply.
If
Fa timeout
is specified as
NULL
however, the routine will instead use
TCP
and block until a reply is received from the time server.
