Example code:

```julia
using DataStructures

# disable SIG_INT
println("To termiate the logger, press <CTRL>+<C>!")
ccall(:jl_exit_on_sigint, Void, (Cint,), 0)

# use an array with one element for global variables, such that they can be declared as const
const terminate = [false]

# create a queue for buffering incoming messages
const q = Queue(String)

# background loop for receiving UDP messages, terminated with <ctrl> + <c>
function receiveData(server_ip)
	global terminate
	udpsock = UDPSocket()
	# setopt(udpsock, enable_broadcast=true)
	bind(udpsock, server_ip, port)
	i = 0
	try
		while true
			msg = String(copy(recv(udpsock)))
			enqueue!(q, msg)
		end
	catch my_exception
		if isa(my_exception, InterruptException)
			close(udpsock)
			terminate[1] = true
		end
	end
end

server_ip = IPv4("0.0.0.0")
@async receiveData(server_ip) # start the background task of receiving UDP packages

```
