Instead it should just be a callback API full stop. It's up to the client if they want to filter, or find a specific entry, or whatever. The lifetime rules are such that an entry exists whilst the handle is open, so there's no issues with borrowing pointers in the callback etc. > Imagine virt-manager building a 2 level hiearchy.

It really doesn't need library help... regards john _______________________________________________ et-mgmt-tools mailing list et-mgmt-tools@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/et-mgmt-tools
