Hi All
I would like to create a sample application for ZFS using C++/C and
libzfs.
I am very new to ZFS, I would like to have an some information about
ZFS API.
Even some sample code will be useful.
Looking for help and constructive suggestion.
libzfs is a private interface (see Solaris man page for attributes)
It was not designed to be used directly by external programmers.
I can't comment on what Oracle might or might not be doing, but for the
open source community, there is a project underway called "libzfs_core"
that is developing a stable library for external consumers. For more info,
see
http://smartos.org/2012/01/13/the-future-of-libzfs/
That's good news. It's a shame it wasn't announced here.
I'm one of the many Matt refers to in the presentation who has been
using libzfs. I started using it pretty much the week ZFS shipped and
it a was a long while after that I discovered the the private nature of
the interface (through a posting here asking for an enhancement!).
Since then I have been using a thin wrapper to decouple my applications
from changes to the API. Generally the API has been stable for basic
operations such as iteration and accessing properties. Not so for send
and receive!
I have a simple (150 line) C++ wrapper that supports iteration and
property access I'm happy to share if anyone is interested.
