Hi Chip, What do you mean by "controlling zfs"? The answer to your question will depend on your requirements. If you're looking to do anything beyond checking dataset existence, creating datasets[1], snapshot, clone, destroying snaps, send, receive, rollback[2], managing bookmarks, or managing holds, you're going to find libzfs_core lacking.
At my last gig, I built a C++ abstraction layer on top of libzfs_core, libzfs, and libzpool, preferring the _core interfaces wherever extant (since they are MT-safe). If you're willing to deal with the complexity of libzfs and libzpool, it's possible to build quite complex pool and dataset management applications in C/C++ on top of the zfs apis (we were building an async replicated geographically distributed object store for a DR product.) Cheers, -Tom [1] (NB: for zpl, lzc_create does not imply mount -- after all, this involves a complicated sequence of vfs ops that should be done separately by the user in the sequence desired) [2] as with [1], only the dsl layer stuff: no vfs ops are performed On Wednesday, August 31, 2016, Schweiss, Chip <[email protected] <javascript:_e(%7B%7D,'cvml','[email protected]');>> wrote: > What is the status of libzfs_core?
