I am trying to keep a watch on an object in Ceph, but I don't know how to do it. I searched for examples online but could not find any. Found some documentation here. It says that I can use rados_watch to watch an object for changes. But I dont know how to implement it in C, especially the rados_watchcb_t part. It says rados_watchcb_t would contain the action to execute on notification. How do I declare it?
This is what I tried:
rados_watchcb_t rados_watch = printf("Updated");
But this gives an error.
