For non-conforming compilers there might be a chance 35 that it works anyway thanks to workarounds in the type traits library. Visual 36 C++ 6/7.0 has a limited support for arrays: as long as the arrays are of built-in 37 type it should work. 38 </p> 39<p> 40 Notice also that some compilers cannot do function template ordering properly. 41 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 42 definition instead of overloaded versions for const and non-const arguments. 43 So if one cares about old compilers, one should not pass rvalues to the functions. 44 </p> 45<p> 46 For maximum portability you should follow these guidelines: 47 </p> 48<div class="orderedlist"><ol class="orderedlist" type="1"> 49<li class="listitem"> 50 do not use built-in arrays, 51 </li> 52<li class="listitem"> 53 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>, 54 <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> 55 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 56 and assignment operators, 57 </li> 58<li class="listitem"> 59 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> 60 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> 61 whenever your code by intention is read-only; this will also solve most 62 rvalue problems, 63 </li> 64<li class="listitem"> 65 do not rely on ADL: 66 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> 67<li class="listitem"> 68 if you overload functions, include that header before the headers 69 in this library, 70 </li> 71<li class="listitem"> 72 put all overloads in namespace boost. 73 </li> 74</ul></div> 75 </li> 76</ol></div> 77</div> 78<table xmlns:rev="http://www.cs.rpi.edu/~gregod/boost/tools/doc/revision" width="100%"><tr> 79<td align="left"></td> 80<td align="right"><div class="copyright-footer">Copyright © 2003-2010 Thorsten Ottosen, 81 Neil Groves<p> 82 Distributed under the Boost Software License, Version 1.0.
