The <b>BOOST_PP_TUPLE_REM</b> macro expands to a macro that removes the parentheses from a <i>tuple</i>.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_TUPLE_REM</b>(<i>size</i>)
<b>BOOST_PP_TUPLE_REM</b>(<i>size</i>)<br>
<br>
or<br>
<br>
<b>BOOST_PP_TUPLE_REM</b>(<i>size</i>) <sup>(v)</sup><br>
</div>
<h4>Arguments</h4>
<dl>
<dt>size</dt>
<dd>
The size of the <i>tuple</i> from which the parentheses are to be removed.&nbsp;
Valid <i>tuple</i> sizes range from <i>0</i> to <b>BOOST_PP_LIMIT_TUPLE</b>.&nbsp;
Valid <i>tuple</i> sizes range from <i>1</i> to <b>BOOST_PP_LIMIT_TUPLE</b>.&nbsp;
</dd>
</dl>
<h4>Remarks</h4>
<div>
The <i>size</i> argument must be the actual size of the <i>tuple</i>.
The <i>size</i> argument must be the actual size of the <i>tuple</i> in the non-variadic version.<br>
<br>
For the variadic version <sup>(v)</sup>&nbsp;the
size may be left out
completely so that the macro can be invoked as BOOST_PP_TUPLE_REM(); you may get a warning from some compilers, but the
functionality will still work. If you specify a size in the variadic
version, it will be ignored, but the warning from some compilers will
not occur.<br>
