I want that program raise an error if reach for example 30
seconds of timeout.
My program does something like this. (untested)
Socket s = new TcpSocket;
s.setOption(SocketOptionLevel.SOCKET, SocketOption.RCVTIMEO,
30.seconds);
s.setOption(SocketOptionLevel.SOCKET, SocketOption.SNDTIMEO,
30.seconds);
auto addresses = getAddress("domain.com", 80);
bool isConnected;
foreach (address; addresses)
{
try
{
s.connect(address);
isConnected = true;
break;
}
catch (SocketException e)
{
// Failed, try next address
writeln(e.msg);
}
}
if (!isConnected) return false; // failed to connect
// Connected
You can tell whether a read timed out by looking at the amount of
bytes read (when `Socket.receive` returns `Socket.ERROR`) and the
value of `std.socket.lastSocketError` (and/or
`core.stdc.errno.errno` equaling EAGAIN).
