Subject: Function prototype with [restrict]
6.7.6 (direct-abstract-declarator) is inconsistent with 6.7.5 (direct-declarator) with respect to omitting an identifier from a declaration to form a type name.
Here is a specific example that shows the problem.
int lio_listio(int, struct aiocb *restrict const[restrict]);is invalid and appears to have to be done as:
int lio_listio(int, struct aiocb *restrict const __FOO[restrict]);
In several contexts, it is necessary to specify a type. This is accomplished using a type name, which is syntactically a declaration for a function or an object of that type that omits the identifier.
So you would think that if
struct aiocb *restrict const __FOO[restrict]is a valid declaration of the object __FOO, then it should follow from the above statement that
struct aiocb *restrict const [restrict]must be a valid type name.
