<a name="id-1.3.15.8.2.2.10.4"></a><h2>Description</h2>
<p>This macro is useful in cases of long mangled C++ names. For example some <code class="computeroutput">void boost::foo(std::string)</code> function name will change to something like <code class="computeroutput">N5boostN3foosE</code> after mangling. Importing function by <code class="computeroutput">N5boostN3foosE</code> name does not looks user friendly, especially assuming the fact that different compilers have different mangling schemes.*</p>
<p>Must be used in scope where FunctionOrVar declared. FunctionOrVar must be a valid C name, which means that it must not contain <code class="computeroutput">::</code>.</p>
<p>Functions or variables in global namespace must not have names same as FunctionOrVar.</p>
<p>Puts all the aliases into the <span class="bold"><strong>"boostdll"</strong></span> read only section of the binary. Almost same as <a class="link" href="BOOST_DLL_ALIAS.html" title="Macro BOOST_DLL_ALIAS">BOOST_DLL_ALIAS</a>(FunctionOrVar, FunctionOrVar).</p>
<p>
<span class="bold"><strong>Example:</strong></span> </p>
<pre class="programlisting"><span class="keyword">namespace</span> <span class="identifier">foo</span> <span class="special">{</span>
<span class="keyword">void</span> <span class="identifier">bar</span><span class="special">(</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span><span class="special">&amp;</span><span class="special">)</span><span class="special">;</span>
