-<div style="margin-left: 0px;"> The <b>BOOST_PP_CALL_OVERLOAD</b> variadic macro invokes a non-variadic macro having a given number of parameters.<br>
- </div>
-<h4>Usage</h4>
-<div class="code"> <b>BOOST_PP_CALL_OVERLOAD</b>(<i>prefix</i>,...) <sup>(v)</sup><br>
- </div>
-<h4>Arguments</h4>
-<dl>
-<dt>prefix<br>
-</dt><dd>
- The prefix of the non-variadic macro name.</dd><dt>...<br>
-</dt><dd><i>
- Variadic data</i>. The number of variadic data
-elements, as determined by BOOST_PP_VARIADIC_SIZE, is appended to the
-prefix to form the output non-variadic macro name, and then the non-variadic macro name is invoked passing this <i>variadic data</i> as parameters.<br>
-</dd>
-</dl>
-<h4>Remarks</h4>
-<div> This macro creates a macro name which depends on the number of
-elements of variadic data using BOOST_PP_OVERLOAD and then invokes that
-macro passing the <i>variadic data</i>. In this way one can invoke a
-variadic macro with a variable number of parameters which calls one of
-a series of non-variadic macros doing very similar things. If such a macro name does not exist taking the specified number of
-arguments as determined by the number of elements of the variadic data,
-a preprocessor error will occur.<br>
-<br>
-The macro overcomes a problem using BOOST_PP_OVERLOAD with Visual C++.
-However, when used with Visual C++ the macro can not be recursively
-invoked, so BOOST_PP_OVERLOAD must be used instead in a slightly
-different way. To see how this is done look at the code in
-boost/preprocesor/tuple/detail/use_overload.hpp. If there is no need to
-recursively invoke BOOST_PP_OVERLOAD the macro can be used with Visual
-C++ without any problems. The recursive invocation problem using
-BOOST_PP_CALL_OVERLOAD does not exist for other compilers tested.<br>
