   8                 The <b>BOOST_PP_TUPLE_REM</b> macro expands to a macro that removes the parentheses from a <i>tuple</i>.
   9         </div>
  10         <h4>Usage</h4>
  11                 <div class="code">
  12                         <b>BOOST_PP_TUPLE_REM</b>(<i>size</i>)<br>
  13 <br>
  14 or<br>
  15 <br>
  16 <b>BOOST_PP_TUPLE_REM</b>(<i>size</i>) <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a><br>
  17                 </div>
  18         <h4>Arguments</h4>
  19                 <dl>
  20                         <dt>size</dt>
  21                         <dd>
  22                                 The size of the <i>tuple</i> from which the parentheses are to be removed.&nbsp;
  23                                 Valid <i>tuple</i> sizes range from <i>1</i> to <b>BOOST_PP_LIMIT_TUPLE</b>.&nbsp;
  24                         </dd>
  25                 </dl>
  26         <h4>Remarks</h4>
  27                 <div>
  28                         The <i>size</i> argument must be the actual size of the <i>tuple</i> in the non-variadic version.<br>
  29 <br>
  30 For the variadic version <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a>&nbsp;the
  31 size may be left out
  32 completely so that the macro can be invoked as BOOST_PP_TUPLE_REM(); you may get a warning from some compilers, but the
  33 functionality will still work. If you specify a size in the variadic
  34 version, it will be ignored, but the warning from some compilers will
  35 not occur.<br>
  36 <br>Note: For Visual C++ 8.0 ( Visual Studio 2005 ) you must specify the correct <i>size</i> argument as in the non-variadic version.<br>
