title: C - fork() and sharing memory
body: <p>I need my parent and child process to both be able to read and write the same variable (of type int) so it is "global" between the two processes.</p>
  
  <p>I'm assuming this would use some sort of cross-process communication and have one variable on one process being updated.</p>
  
  <p>I did a quick google and IPC and various techniques come up but I don't know which is the most suitable for my situation.</p>
  
  <p>So what technique is best and could you provide a link to a noobs tutorial for it.</p>
  
  <p>Thanks.</p>
