◆ CheckArrayDesignatorExpr()

ExprResult CheckArrayDesignatorExpr	(	Sema &	S,

static

Check that the given Index expression is a valid array designator value.

This is essentially just a wrapper around VerifyIntegerConstantExpression that also checks for negative values and produces a reasonable diagnostic if there is a failure. Returns the index expression, possibly with an implicit cast added, on success. If everything went okay, Value will receive the value of the constant expression.
