This capability was removed in BSD, presumably because nothing used it any more. Third party system software written for Unix (like ZFS) requires this to work without significant modifications. What is an undescribed, direct ioctl, and where is it documented? I thought NetBSD was a kind of Unix. Perhaps you meant as used by insert version of unix here. And please don't write log messages with lines longer than 80 chars. Ok supremeleader@ Who? --apb (Alan Barrett)

a...@cequrux.com said: What is an undescribed, direct ioctl, and where is it documented? As I understand it this is where the third ioctl argument is used as data instead of a pointer to data. This is only useful to provide source compatibility to non-BSD sources, and there are ways to get that without tainting the interface at that high level. Also, there might be problems with 32/64bit compatibility. Look for the term gross and disgusting hack in sys/dev/wscons/wsdisplay_compat_usl.c. best regards Matthias Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
