[cfe-dev] DeclRefExpr: how to distinguish between variable ref and function ref?

[jignesh vasoya]

Hi,

I am traversing C source code using ASTConsumer.
bool Visit(Stmt *S)
{
.........
........
      if( isa<DeclRefExpr>(S) )
                ProcessDeclRefExpr(cast<DeclRefExpr>(S));
..........
........
}

Whenever any variable or function is referred if condition(given in above
code fragment ) evaluates to true
and it is processed by ProcessDeclRefExpr function.

I want to handle variable and functions ref differently.
How can i distinguish between variable and function ref??????/
