hasUnparsedDefaultArg - Determines whether this parameter has a default argument that has not yet been parsed. This will occur during the processing of a C++ class whose member functions have default arguments, e.g.,

class X {
public:
void f(int x = 17); // x has an unparsed default argument now
}; // x has a regular default argument now

bool clang::ParmVarDecl::isKNRPromoted ( ) const
inline

True if the value passed to this parameter must undergo K&R-style default argument promotion:

C99 6.5.2.2. If the expression that denotes the called function has a type that does not include a prototype, the integer promotions are performed on each argument, and arguments that have type float are promoted to double.

setOwningFunction - Sets the function declaration that owns this ParmVarDecl. Since ParmVarDecls are often created before the FunctionDecls that own them, this routine is required to update the DeclContext appropriately.
