Error in creating TCP client in lua -

i trying create tcp client in lua

local host, port = host, port local socket = require("socket") client = socket.tcp(); client:connect(host, port); client:send("hello user");

this works fine when add 

while true     local s, status, partial = client:receive()     print(s or partial)     if status == "closed" break end end

to read data socket block total execution of code.

by default, luasocket i/o operations blocking. need use socket.settimeout(0) (settimeout) disable blocking. can check "timeout" value returned status , act accordingly.

depending on how data being sent, this answer may relevant well.
