Yes. But it is conventional to interpret a short write as being a failure. Returning less bytes than were requested in the write indicates that the rest failed. It just doesn't give the exact nature of the failure (EIO vs ENOSPC etc.) For regular files, a short write is never permitted unless there are errors of some description. --Stephen - 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/
