<p class="MsoNormal"><span lang="EN-US">Using c-index-test.exe I’m learning clang code completion for C++.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I have an issue to get the current parameter list of a C++ function. While it works for a C function, I get nothing which can be evaluated in case of C++ function.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> I use the following command line: <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">“c-index-test -code-completion-at=x.cpp:9:10 -x c++ -fsyntax-only -x.cpp”<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">If the function is a C function, “c-index-test” returns a function parameter list for the function with the node ‘CurrentParameter’ which is important for code completion:<o:p></o:p></span></p>

<o:p></o:p></span></p>
