title: Replace function or define by the text itself
body: <p>How can I replace all occurence of</p>
  
  <pre><code>check_free_set_to_null(&amp;pointer)
  </code></pre>
  
  <p>by</p>
  
  <pre><code>if (pointer)
  {
      free(pointer)
      printf(pointer have been freed)
  }
  else
  {
      printf(pointer couldnt had been freed)
      return (1)
  }
  </code></pre>
  
  <p>maybe using some sort of</p>
  
  <p>{1} = check_free_set_to_null(CONTENT)</p>
  
  <pre><code>  if ({1})
      {
          free({1})
          printf({1} have been freed)
      }
      else
      {
          printf({1} couldnt had been freed)
          return (1)
      }
  </code></pre>
  
  <p>how could I do that ?
  (take note thats its not exactly what that have to be replaced, its just an example)
  Im not looking for the compiler to interpret it as multiple line, im looking for modifying the file.</p>
