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.
As others said, sysctl is one way to go, but might not be very
convenient if the amount of data is large. I'd rather setup a device and
a simple protocol to read/write to/from it.
