The first sentence of the man pages for select suggests that something interesting has happened inbetween select()'s. Later on it states "more precisely, to see if a read will not block", which is still different from "if characters become available for reading". The "precisely" fits my issue, and not the others. - 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/
