<div class="refsect1">
<a name="id-1.3.13.8.2.2.8.4"></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::sting)</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. AliasName is the name that won't be mangled and can be used as a portable import name.</p>
<p>Can be used in any namespace, including global. FunctionOrVar must be fully qualified, so that address of it could be taken. Multiple different aliases for a single variable/function are allowed.</p>
<p>Make sure that AliasNames are unique per library/executable. Functions or variables in global namespace must not have names same as AliasNames.</p>
<p>Same AliasName in different translation units must point to the same FunctionOrVar.</p>
<p>Puts all the aliases into the <span class="bold"><strong>"boostdll"</strong></span> read only section of the binary. Equal to <a class="link" href="BOOST_DLL_ALIAS_SECTIONED.html" title="Macro BOOST_DLL_ALIAS_SECTIONED">BOOST_DLL_ALIAS_SECTIONED</a>(FunctionOrVar, AliasName, boostdll).</p>
