[![Build Status](https://travis-ci.org/moteus/lzmq-pool.png?branch=master)](https://travis-ci.org/moteus/lzmq-pool)

This library provide ability to use same sockets from different

Lua states / threads in same process.

This library depend from [LUQ](https://github.com/moteus/lua-luq).

###Usage

```Lua

-- Hello World client (http://zguide.zeromq.org/page:all)

-- Use one socket from two os threads.

local zmq      = require "lzmq"

local zthreads = require "lzmq.threads"

local zpool    = require "lzmq.pool"

-- 

local QUEUE_NAME = "hwclient"

local NUM_SOCKETS = 1

local SOCKETS_OPT = {zmq.REQ, connect = "tcp://127.0.0.1:5556"}

local pool = zpool.new(QUEUE_NAME)

pool:init(zmq.context(), NUM_SOCKETS, SOCKETS_OPT)

-- Now we should just keep alive `pool` object

-- Worker thread

local worker = string.dump(function(POOL, TID)

  local zpool  = require "lzmq.pool"

  local ztimer = require "lzmq.timer"

  -- We can get this ID for example from config.

  local pool = zpool.new(POOL)

  for i = 1, 5 do

    pool:acquire(function(s)

      print(TID .. ' SEND: ', s:send("hello"))

      print(TID .. ' RECV: ', s:recv())

    end)

    ztimer.sleep(500)

  end

end)

-- We create independent tasks

-- and tell them which pool to use.

local t1 = zthreads.run(nil, worker, QUEUE_NAME, 1) t1:start()

local t2 = zthreads.run(nil, worker, QUEUE_NAME, 2) t2:start()

t1:join() t2:join()

```
