title: LOCAL and GLOBAL Functions in C
body: <p>I'm rooting around some really old C code and have come across the following: </p>
  
  <pre><code>GLOBAL void Input_Channels()
  {
      // removed
  }
  </code></pre>
  
  <p>There are also plenty of similar, but LOCAL.</p>
  
  <p>What is this? I can't see any information anywhere about the LOCAL / GLOBAL function.</p>
