For pointers of for anything else. if (v) is the same as if (v != 0) [6.8.4.1p2], and if v is a pointer, 0 in that comparison becomes a null pointer constant [6.5.9p5]. - 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/
