◆ checkNullabilityTypeSpecifier()

static bool checkNullabilityTypeSpecifier	(	TypeProcessingState &	state,
		QualType &	type,
		ParsedAttr &	attr,
		bool	allowOnArrayType
	)

static

Applies a nullability type specifier to the given type, if possible.

Parameters

state	The type processing state.
type	The type to which the nullability specifier will be added. On success, this type will be updated appropriately.
attr	The attribute as written on the type.
allowOnArrayType	Whether to accept nullability specifiers on an array type (e.g., because it will decay to a pointer).

Returns: true if a problem has been diagnosed, false on success.

◆ maybeMovePastReturnType()

static DeclaratorChunk* maybeMovePastReturnType	(	Declarator &	declarator,

Given the index of a declarator chunk, check whether that chunk directly specifies the return type of a function and, if so, find an appropriate place for it.

Parameters

i	- a notional index which the search will start immediately inside
onlyBlockPointers	Whether we should only look into block pointer types (vs. all pointer types).
