[cfe-dev] How can I get the template argument in a TypedefDecl ?

[Yaron Keren]

Hi,

Try this:

std::string getTypeName(QualType QT) {
  std::string TypeName;
  llvm::raw_string_ostream TypeNameOS(TypeName);
  LangOptions LO;
  QT.print(TypeNameOS, PrintingPolicy(LO), "identifier");
  TypeNameOS.flush();
  return TypeName;
}

Yaron
