Tried this myself: 11991 cdcontrol CALL open(0x7fffffffe130,0,0x9) 11991 cdcontrol NAMI "/dev/acd0" 11991 cdcontrol RET open 3 11991 cdcontrol CALL ioctl(0x3,CDIOCALLOW,0) 11991 cdcontrol RET ioctl 0 11991 cdcontrol CALL ioctl(0x3,CDIOCEJECT,0) 11991 cdcontrol RET ioctl -1 errno 16 Device busy 11991 cdcontrol CALL exit(0xffffffff) It is a question for me how atapi-cd should behave on CDIOCALLOW command issued on an opened disk (by something other than the entity doing ioctl, i.e. geom acr > 1). Maybe it should work the same way as for CDIOCEJECT, maybe geom ace should be taken into account somehow. Part of me says: do not allow unlocking tray if something is mounted, the other part says: let user do what he wants. Maybe the easiest solution here is to change cdcontrol to do only CDIOCEJECT without CDIOCALLOW ? -- Andriy Gapon _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
