title: Windows function names followed by @ number symbol?
body: <p>I'm programming for Windows in assembly in NASM, and i found this in the code:</p>
  <pre><code>extern _ExitProcess@4
    ;Rest of code...
    ; ...
  call  _ExitProcess@4
  </code></pre>
  <p>What does the <code>@4</code> mean in the declaration and call of a winapi library function?</p>
