[cfe-dev] Getting FunctionDecl argument name as string

[Aleksei Sidorin]

Hello Sandeep,
ParmVarDecl is a NamedDecl so I think you can use getName() method that 
returns StringRef:
http://clang.llvm.org/doxygen/classclang_1_1NamedDecl.html#aaf790590f634520a99e0b45699fc45c3
or getNameAsString that returns std::string:
http://clang.llvm.org/doxygen/classclang_1_1NamedDecl.html#a99d453b314da693c106d5acbc598fc6c
