<p>Thank you for your answer.</p>

</p>
<p>I have found the solution in the Clang Devs archive. This is what I did </p>
<p><br>
</p>
<p></p>
<div>if (func_decl->hasBody()) //in order to get the definitions body and then locate it in the corresponding file</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>{</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>const FileEntry *file_entry = astContext->getSourceManager().getFileEntryForID(astContext->getSourceManager().getFileID(func_decl->getLocStart()));</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>string sourcepath = file_entry->getName();</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>const int idx = sourcepath.find_last_of("\\/");</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>if (std::string::npos != idx) //extract the filename from the entire path</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>{</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span> <span class="Apple-tab-span" style="white-space:pre">
</span>filename = sourcepath.substr(idx + 1);</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>}</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>}</div>

<p>My answer is just for the archive.</p>

<div dir="ltr">Hi,
<div><br>
</div>
<div>You could use the getFilename() API by SourceManager. Get the function's startLoc and then pass it to the getFileName( ). </div>

<div>Hi all,</div>
<div><br>
</div>
<div>I have an ASTvisitor and when it visits a CallExpr node, if the expression is a function call I would like to retrieve the filename of the source code where the called function is defined within. Is it possible?</div>
<div><br>
</div>
<div>Thank you</div>
