Enums are really nice substitute for integer constants instead of #defines. Enums obey scope rules, #defines do not.
However enums are not widely used because of 1. tradition and style 2. awkward syntax required: enum { ABC = 123 };
Maybe a macro could help
#define CONST(a, N) enaum { a = N }
CONST(ABC, 123); CONST(DEF, 456); -- vda - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
