title: Empty function macros
body: <p>If I define a function macro with no actual body, is it like an empty string with the compiler (i.e. It doesn't generate any extra instructions at compile time)?</p>
  
  <p>Example:</p>
  
  <pre><code>#define SomeMacro(a)
  
  SomeMacro("hello"); // This line doesn't add any instructions, does it?
  </code></pre>
