Efl.Net.Dialer.Udp (class)


Connects to a remote UDP server.

UDP proxies are not supported, not even using SOCKSv5.

In addition to an IP:PORT, the UDP address to dial may be an IPv4 broadcast (, 'any ip' (IPv4) '::' (IPv6) or a multicast of both IPv4 and IPv6, then the group will be joined automatically.

Any IP ( or '::') and multicast addresses will allow incoming packets on Efl.Io.Reader.read regardless of their source. If using a regular IP, packets that do not match the remote peer will be dropped as spurious, returning EAGAIN.

To allow finer control, see:

- Efl.Net.Socket.Udp.bind: choose the local address to bind. - Efl.Net.Socket.Udp.multicast_join: join other multicast groups. - Efl.Net.Socket.Udp.multicast_loopback: if packets should be delivered locally or only to remote peers. - Efl.Net.Socket.Udp.multicast_time_to_live: how far, in number of hops, the packet should go.

closed Notifies closed, when property is marked as true
can_read,changed Notifies can_read property changed.
eos Notifies end of stream, when property is marked as true.
can_write,changed Notifies can_write property changed.
error Called when a error occurred on the file descriptor
read Called when a read happened on the file descriptor
