static bool AttributesMatch	(	const Decl *	Decl1,
		const Decl *	Decl2,
		bool &	AvailabilityArgsMatch
	)		[static]

AttributesMatch - This routine checks list of attributes for two decls. It returns false, if there is a mismatch in kind of attributes seen in the decls. It returns true if the two decls have list of same kind of attributes. Furthermore, when there are availability attributes in the two decls, it sets the AvailabilityArgsMatch to false if availability attributes have different versions, etc.

static bool AuditedType

(

AT

)

[static]

AuditedType - This routine audits the type AT and returns false if it is one of known CF object types or of the "void *" variety. It returns true if we don't care about the type such as a non-pointer or pointers which have no ownership issues (such as "int *").

static bool AvailabilityAttrsMatch	(	Attr *	At1,
		Attr *	At2
	)		[static]

AvailabilityAttrsMatch - This routine checks that if comparing two availability attributes, all their components match. It returns true, if not dealing with availability or when all components of availability attributes match. This routine is only called when the attributes are of the same kind.
