[cfe-dev] Getting FunctionDecl argument name as string

[Sandeep K Chaudhary]

Hi guys,

In a FunctionDecl with body, I want to get all the argument names and types.

I am able to get these on console by printing to llvm::errs() as following

*llvm::errs() << f->getParamDecl(i)->getOriginalType().getAsString() <<
"\n";*
*llvm::errs() << *f->getParamDecl(i)<< "\n";*

The first one is a string. However, I can not get the string for argument
name. Though, I am able to successfully print it using llvm::errs().

Can someone please help me with it? If I can write it to some file stream,
that would also work.

I looked at ParmVarDecl but I didn't find anything useful to achieve it.

Sandeep K Chaudhary.
