For non-conforming compilers there might be a chance that it works anyway thanks to workarounds in the type traits library. Visual C++ 6/7.0 has a limited support for arrays: as long as the arrays are of built-in type it should work. </p> <p> Notice also that some compilers cannot do function template ordering properly. In that case one must rely of <a class="link" href="reference/concept_implementation/semantics/metafunctions.html" title="Metafunctions"><code class="computeroutput"><span class="identifier">range_iterator</span></code></a> and a single function definition instead of overloaded versions for const and non-const arguments. So if one cares about old compilers, one should not pass rvalues to the functions. </p> <p> For maximum portability you should follow these guidelines: </p> <div class="orderedlist"><ol class="orderedlist" type="1"> <li class="listitem"> do not use built-in arrays, </li> <li class="listitem"> do not pass rvalues to <a class="link" href="reference/concept_implementation/semantics/functions.html" title="Functions"><code class="computeroutput"><span class="identifier">begin</span></code></a><code class="computeroutput"><span class="special">()</span></code>, <a class="link" href="reference/concept_implementation/semantics/functions.html" title="Functions"><code class="computeroutput"><span class="identifier">end</span></code></a><code class="computeroutput"><span class="special">()</span></code> and <a class="link" href="reference/utilities/iterator_range.html" title="Class iterator_range"><code class="computeroutput"><span class="identifier">iterator_range</span></code></a> Range constructors and assignment operators, </li> <li class="listitem"> use <a class="link" href="reference/concept_implementation/semantics/functions.html" title="Functions"><code class="computeroutput"><span class="identifier">const_begin</span></code></a><code class="computeroutput"><span class="special">()</span></code> and <a class="link" href="reference/concept_implementation/semantics/functions.html" title="Functions"><code class="computeroutput"><span class="identifier">const_end</span></code></a><code class="computeroutput"><span class="special">()</span></code> whenever your code by intention is read-only; this will also solve most rvalue problems, </li> <li class="listitem"> do not rely on ADL: <div class="itemizedlist"><ul class="itemizedlist" type="disc"> <li class="listitem"> if you overload functions, include that header before the headers in this library, </li> <li class="listitem"> put all overloads in namespace boost. </li> </ul></div> </li> </ol></div> </div> <table xmlns:rev="http://www.cs.rpi.edu/~gregod/boost/tools/doc/revision" width="100%"><tr> <td align="left"></td> <td align="right"><div class="copyright-footer">Copyright © 2003 -2010 Thorsten Ottosen, Neil Groves<p> Distributed under the Boost Software License, Version 1.0.
