This reminds me the unfortunate (and much needed) lack of an unified way to send/receive out-of-band data to/from a regular fd. Something like: oob = fd_open(fd, channel, flags); write(oob, ...) read(oob, ....) close(oob); Don't you think it's time to introduce it and to start to avoid the proliferation of different tricky ways to do the same things? -- Abramo Bagnara mailto:abramo.bagnara@libero.it Opera Unica Phone: +39.546.656023 Via Emilia Interna, 140 48014 Castel Bolognese (RA) - Italy - 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/ | ||||||||||||
