   9                 The <b>BOOST_PP_IS_ITERATING</b> macro is defined when a <i>file-iteration</i> is in progress.

  11         <h4>Usage</h4>
  12                 <div class="code">
  13                         #if !defined(<b>BOOST_PP_IS_ITERATING</b>) // ...

  17                         If a <i>file-iteration</i> is in progress, this macro is defined as <i>1</i>.&nbsp;
  18                         This means that the following will also work:
  19                         <div>
  20                                 #if !<b>BOOST_PP_IS_ITERATING</b> // ...
  21                         </div>
  22                 </div>
  23                 <div>
  24                         This macro is defined to guard a file from infinite inclusion.
