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.
