<div style="margin-left: 0px;"> The <b>BOOST_PP_IS_BEGIN_PAREN</b>S
determines whether the input starts with a set of parenthesis.</div>
<h4>Usage</h4>
<div class="code"> <b>BOOST_PP_IS_BEGIN_PARENS</b>(...) <a href="../topics/variadic_macros.html#VNotation"

<h4>Arguments</h4>
<h4>&nbsp;&nbsp;&nbsp; ...&nbsp;&nbsp;&nbsp; <span style="font-weight: normal;">&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp; The input as variadic data.</span></h4>
<h4>Remarks</h4>
<div> If the input input begins with a parenthesis, with any data within
that parenthesis, the macro returns 1, otherwise it returns 0. Data may
follow the beginning parenthesis and the macro still will return 1.<br>
<br>
For Visual Studio 2005 ( VC8 ) the input data must be a single parameter
else a compilation error will occur.</div>
