Patrick, Thanks for responding.
I agree that I can use zoo_exists and zoo_get to get the version of the znode as it exists currently. The problem I am trying to solve is that getting the version from struct Stat in either zoo_exists or zoo_get may not be the same version that my last successful zoo_set used. I would like to get the version that denotes my last successful zoo_set() operation to a particular znode. I understand that the data and version to the znode may change immediately one or multiple times after my zoo_set() and this is fine, but I would still like to know the znode's versions of the data I set.
