<div style="margin-left: 0px;">
The <b>BOOST_PP_ITERATION_LIMITS</b> macro is a user-defined <i>named external argument</i> used by <b>BOOST_PP_ITERATE</b>.
It denotes the lower and upper bounds of a <i>file-iteration</i>.
</div>
<h4>Usage</h4>
<div class="code">
#define <b>BOOST_PP_ITERATION_LIMITS</b> (<i>start</i>, <i>finish</i>)
</div>
<h4>Arguments</h4>
<dl>
<dt>start</dt>
<dd>
The lower bound (inclusive) of a <i>file-iteration</i>.
Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_ITERATION</b>.
</dd>
<dt>finish</dt>
<dd>
The upper bound (inclusive) of a <i>file-iteration</i>.
Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_ITERATION</b>.
</dd>
</dl>
<h4>Remarks</h4>
<div>
Note that there is a whitespace character after the macro identifier.
</div>
<div>
This macro is part of the secondary method of passing arguments to <b>BOOST_PP_ITERATE</b>.
The other part is <b>BOOST_PP_FILENAME_<i>x</i></b>. Both <i>start</i> and <i>finish</i> are <i>evaluated parameters</i>.
This implies that they may include simple arithmetic.
</div>
<div>
This macro is automatically undefined for reuse by a call to <b>BOOST_PP_ITERATE</b>.
</div>
