Valid values range from <i>0</i> to <b>BOOST_PP_ARRAY_SIZE</b>(<i>array</i>). </dd> <dt>elem</dt> <dd> The element to insert. </dd> </dl> <h4>Remarks</h4> <div> This macro inserts <i>elem</i> before the element at index <i>i</i>. </div> <div> If the operation attempts to create an <i>array</i> that is larger than <b>BOOST_PP_LIMIT_TUPLE</b>, the result is undefined. </div> <div> This macro uses <b>BOOST_PP_WHILE</b> interally. Therefore, to use the <i>d</i> parameter passed from other macros that use <b>BOOST_PP_WHILE</b>, see <b>BOOST_PP_ARRAY_INSERT_D</b>. </div> <h4>See Also</h4> <ul> <li><a href="array_insert_d.html">BOOST_PP_ARRAY_INSERT_D</a></li> </ul> <h4>Requirements</h4> <div> <b>Header:</b> <a href="../headers/array/insert.hpp.html"><boost/preprocessor/array/insert.hpp></a> </div> <h4>Sample Code</h4> <div><pre> #include <<a href="../headers/array/insert.hpp.html">boost/preprocessor/array/insert.hpp</a>> #define ARRAY (3, (a, b, d)) <a href="array_insert.html">BOOST_PP_ARRAY_INSERT</a>(ARRAY, 2, c) // expands to (4, (a, b, c, d)) </pre></div> </body> </html>
