- The <b>BOOST_PP_INCLUDE_SELF</b> macro includes a file indirectly.
- </div>
- <h4>Usage</h4>
- <div class="code">
- #include <b>BOOST_PP_INCLUDE_SELF</b>()
- </div>
- <h4>Arguments</h4>
- <dl>
- <dt>filename</dt>
- <dd>
- A quoted or angle-bracketed filename to be included by <b>BOOST_PP_INCLUDE_SELF</b>.
- </dd>
- </dl>
- <h4>Remarks</h4>
- <div>
- <b>BOOST_PP_INDIRECT_SELF</b> must be defined prior to using this macro.
- </div>
- <div>
- Most preprocessors will not allow a file to directly include itself--even when the file protects itself from such a scenario.
- This macro, in combination with <b>BOOST_PP_INDIRECT_SELF</b> allows a file to include itself indirectly.
- </div>
- <div>
- While <b>BOOST_PP_INDIRECT_SELF</b> is being included, <b>BOOST_PP_INCLUDE_SELF</b> defines the macro <b>BOOST_PP_IS_SELFISH</b> to <i>1</i>.
- When it returns from the inclusion, <b>BOOST_PP_IS_SELFISH</b> is undefined.
