I regret I haven't got the time to investigate this for you. But on a 13/amd64 system, a cd /usr/src followed by a grep -r -F libnvpair.h . returned some results that may be of interest to you in sorting this out. ./lib/libbe/be.h:#include <libnvpair.h> for example. The same could be performed against libzfs.h. If including libzfs.h didn't work, and including first libzfs.h along with libnvpair.h errored with duplicates. It may be the case that you need to only include libnvpair.h, which may pull in libzfs.h. IDK but thought I'd mention it. Sorry, that's all I've got. HTH --Chris > > Thank you.
