llvm dev - Mar 2018 - How to read String value of GlobalVariable?

Hi
 I have IR Code like

...
@path = private constant [6xi8] c"abcde\00"
...


--- Code from Pass ---
GlobalVariable * GVPath = ....  // contains @path

I want to convert "abcde" to StringRef. Can you  help me with
GlobalVariable API?

GlobalVariable::getInitializer() --> Constant*  // How to get exact value
äbcde from here?

```
if(GVPath->hasInitializer()){
  if(ConstantDataArray*
CDA=dyn_cast<ConstantDataArray>(GVPath->getInitializer())){
  StringRef str=CDA->getAsString();
  }
}
```
