it's still counted as the same instance. Similar for dup or passing descriptors over AF_UNIX sockets. The data is explictly not per-process but per instance. There's not a lot of users actually using this feature, only the tty subsystem and multi-channel sound drivers for the old oss API that allowed multiple opens of /dev/dsp that way come to mind. Lot's of driver use file->private to get at per-device data easily, but that's just a shortcut. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
