LANG.STRUCT.ELLIPSIS

Ellipsis

Does not currently detect violations of this recommendation. Although the recommendation in general cannot be automated, because of the difficulty in enforcing contracts between a variadic function and its invokers, it would be fairly easy to enforce type correctness on arguments to the printf() family of functions
