StringRef::str().c_str() or StringRef::data()?

I am wriitng an LLVM pass to insert instrumentation at certain points of the program. I want to pass the StringRef obtained from getName() as a parameter to a function func(char* s). I can allocate some space on stack using AllocaInst to generate an alloca instruction. But, how can I copy the StringRef to the stack space? -- Thanks & Regards, Dipanjan
