title: How can I pass variables to different processes c++
body: <p>I have multiple processes running via fork() and data coming in from a TCP socket. Based on the a header of the data read in, I want to pass the data to a specific one of the multiple processes.</p>
  
  <p>Is there any way to pass data to a specific process and are there any listeners I can use in that processes as to avoid an infinite waiting loop? </p>
