Hi, I am creating a kernel module and I need to get some information from that module. I can do this with ioctl and pass the data to the user space but it seems a bit unpractical to me, because I do not know the amount of the data - it can differ. I do not know of any way to pass a list of structures to the userspace through ioctl - is there any? So my question is, is there any standard way in FreeBSD to do this ? In linux I would probably use the sysfs, but in FreeBSD I can not find anything similar, except just creating some virtual filesystem on my own and obviously this is not what I want to do. Thanks! -Lukas
