| 8 | <div style="margin-left: 0px;"> The <b>BOOST_PP_ARRAY_POP_FRONT</b> macro | |
| 9 | pops an element from the beginning of an <i>array</i>.</div> | |
| 10 | <h4>Usage</h4> | |
| 11 | <div class="code"> <b>BOOST_PP_ARRAY_POP_FRONT</b>(<i>array</i>) </div> | |
| 12 | <h4>Arguments</h4> | |
| 13 | <dl> | |
| 14 | <dt>array</dt> | |
| 15 | <dd> The <i>array</i> to pop an element from. </dd> | |
| 16 | </dl> | |
| 17 | <h4>Remarks</h4> | |
| 18 | <div> This macro returns <i>array</i> after removing the first | |
| 19 | element. If <i>array</i> has no elements, the result of applying | |
| 20 | this macro is undefined. </div> | |
| 21 | <div> This macro uses <b>BOOST_PP_REPEAT</b> internally. Therefore, | |
| 22 | to use the <i>z</i> parameter passed from other macros that use <b>BOOST_PP_REPEAT</b>, | |
| 23 | see <b>BOOST_PP_ARRAY_POP_FRONT_Z</b> </div> | |
