In this case, the second form should be used when the macro needs to return a value (and you can't use an inline function for whatever reason), whereas the first form should be used at all other times.that's a fair point, although it's certainly not the coding style that's in play now. for example, #define setcc(cc) ({ \ partial_status &= ~(SW_C0|SW_C1|SW_C2|SW_C3); \ partial_status |= (cc) & (SW_C0|SW_C1|SW_C2|SW_C3); })
This _does_ return a value though, bad example. Segher - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
