The <b>BOOST_PP_IS_SELFISH</b> macro is defined when a <i>self-inclusion</i> is in progress.
</div>
<h4>Usage</h4>
<div class="code">
#if !defined(<b>BOOST_PP_IS_SELFISH</b>) // ...
</div>
<h4>Remarks</h4>
<div>
If a <i>self-inclusion</i> is in progress, this macro is defined as <i>1</i>.&nbsp;
This means that the following will also work:
<div>
#if !<b>BOOST_PP_IS_SELFISH</b> // ...
</div>
</div>
<div>
This macro is defined to guard a file from infinite inclusion.
