|

The <b>BOOST_PP_LOCAL_LIMITS</b> macro is a user-defined <i>named external argument</i> used by <b>BOOST_PP_LOCAL_ITERATE</b>.
|
||
</div>
|
||
<h4>Usage</h4>
|
||
<div class="code">
|
||
#define <b>BOOST_PP_LOCAL_LIMITS</b> (<i>start</i>, <i>finish</i>)
|
||
</div>
|
||
<h4>Arguments</h4>
|
||
<dl>
|
||
<dt>start</dt>
|
||
<dd>
|
||
The lower bound (inclusive) of a <i>local 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>local 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 must expand to a <i>2</i>-element <i>tuple</i>.
|
||
The elements of this <i>tuple</i> represent the lower and upper boundaries of a <i>local iteration</i>.
|
||
Both <i>start</i> and <i>finish</i> are <i>evaluated parameters</i>.
|
||
This implies that they can include simple arithmetic expressions (such as <i>1</i> + <i>3</i>), etc..
|
||
</div>
|
||
<div>
|
||
This macro is automatically undefined for reuse by a call to <b>BOOST_PP_LOCAL_ITERATE</b>.

||
</div>
