.SH DESCRIPTION
|
|
.B rtime(\|)
|
|
consults the Internet Time Server at the address pointed to by
|
|
.I addrp
|
|
and returns the remote time in the
|
|
.B timeval
|
|
struct pointed to by
|
|
.IR timep .
|
|
Normally, the
|
|
.SM UDP
|
|
protocol is used when consulting the Time Server.
|
|
The
|
|
.I timeout
|
|
parameter specifies how long the
|
|
routine should wait before giving
|
|
up when waiting for a reply. If
|
|
.I timeout
|
|
is specified as
|
|
.SM NULL\s0,
|
|
however, the routine will instead use
|
|
.SM TCP
|
|
and block until a reply is received from the time server.
|
|
.LP
|
|
The routine returns 0 if it is successful.
|
|
Otherwise,
|
|
it returns \-1 and
|
|
.B errno
|
|
is set to reflect the cause of the error.
