There's no reason you can't pass enum values as u8. But in > that case giving the enum a name doesn't really make sense. > enums are cleaner for these cases, but you also have the case where the enum type itself is variable size depending on the ABI being used. If the type in question isn't being packed in to a user-visible data structure then this will never matter, but it does help to be a bit careful here regardless. Many people were bitten by this in the ARM OABI -> EABI conversion, while other architectures generally managed to get it right from the onset. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
