Threads are pretty portable these days, obviously making it a compile time option could work, but then again performance would be nice and it is _our_ tar. ;) Also, unless you mean 'aio' or 'another process' by "non-blocking/async IO" then I'm pretty sure you are wrong, as there is no other way to do this, disk based files do not really support SIGIO (async IO) or non-blocking IO (NBIO). -- - Alfred Perlstein - Research Engineering Development Inc. - email: [EMAIL PROTECTED] cell: 408-480-4684 _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
