Introduction</h1>
<p>The <a class="el" href="namespaceLHAPDF.html" title="Namespace containing all the LHAPDF wrapper functions.">LHAPDF</a> library provides a set of C++ wrapper functions for its Fortran subroutines. New users should browse this documentation and take a look at the <code>CCTest1.cc</code> and <code>CCTest2.cc</code> example program source files, which are good examples of how the wrapper is used.</p>
<h1><a class="anchor" id="changes"></a>
Recent changes</h1>
<p>The <a class="el" href="namespaceLHAPDF.html" title="Namespace containing all the LHAPDF wrapper functions.">LHAPDF</a> wrapper has been improved in several ways for the <a class="el" href="namespaceLHAPDF.html" title="Namespace containing all the LHAPDF wrapper functions.">LHAPDF</a> v5.4 release:</p>
<ul>
<li>String passing to the Fortran functions from C++ now correctly passes the hidden length argument, fixing problems on 64 bit systems; </li>
<li>The <code><a class="el" href="classLHAPDFWrap.html">LHAPDFWrap</a></code> class has been deprecated in favour of a set of wrapper functions in the <code><a class="el" href="namespaceLHAPDF.html" title="Namespace containing all the LHAPDF wrapper functions.">LHAPDF</a></code> namespace. The class interface was misleading, since no persistent state was involved and two class instances would not have been independent; </li>
<li>Proper C++ <code>std::string</code> arguments can now be used for set names: <code>char*</code> string arguments can still be passed, due to implicit conversion via the string(char*) constructor.</li>
</ul>
