title: Send and receive messages to and from posix child processes?
body: <p>I'm trying to setup a socket based server in Lua that can spin up child processes as needed to handle incoming requests (a simple http server that uses multiple forked processes rather than threading).</p>
  
  <p>I'm trying to use <a href="https://github.com/luaposix/luaposix" rel="nofollow">luaposix</a> for this task, but I don't see a way to communicate/send messages between the parent and children processes.</p>
