OverloadingResult clang::OverloadCandidateSet::BestViableFunction	(	Sema &	S,
		SourceLocation	Loc,
		OverloadCandidateSet::iterator &	Best,
		bool	UserDefinedConversion = false
	)

Find the best viable function on this overload set, if it exists.

Computes the best viable function (C++ 13.3.3) within an overload candidate set.

Parameters:

CandidateSet	the set of candidate functions.
Loc	the location of the function name (or operator symbol) for which overload resolution occurs.
Best	f overload resolution was successful or found a deleted function, Best points to the candidate function found.

Returns:

The result of overload resolution.
