Had the function return "bool", it would have been obvious enough what to do with its return type. A return type of "int" might have hinted towards negative-is-error (in general) or strcmpish values (functions doing string compare work). Now that it returns "unsigned long", one is pressed to look at the function body (not bad per se, but it is a hump) for the return value's semantics. Linus says bool is dangerous to the unsuspecting user — but so is "volatile", microwave ovens, etc. If the kernel really cared for entry-level coders, it would be written in something like MISRA C. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
