requestfrom()

Works exactly as the request method, except it passes address and port as extra parameters to a callback.

Edit

Parameter	Type	Required	Description
handle	int	+	Connection handle
callback	string	+	Plugin script file that will be called with received data
user_data	string	–	Any data which will be passed to callback
size	int	–	Maximum size of the datagram to be retrieved. If omitted, the maximum datagram size is used (which is currently limited by the implementation to 8192 bytes).

Edit

Nothing

					local params = ...

local network = require("network")

if params.event == "requestfrom" then
    network.sendto(
        params.data.handle,
        params.data.user_data .. params.data.datagram,
        params.data.address,
        params.data.port)
    return
end

local handle = network.udp();
network.setsockname(handle, "*", "8021")
network.sendto(handle, "Is there anyone?", "192.168.1.255", "8021")
network.requestfrom(handle, "this_script_name", "Hi, ")
