This feels a bit complex; I had to go read esxFreePrivate() to make sure it would behave if called on a partial object. Would it be any easier to delay the assignment to conn->privateData, and use transfer of ownership semantics, so that the cleanup is unconditional? conn->privateData = priv; priv = NULL; result = VIR_DRV_OPEN_SUCCESS; cleanup: esxFreePrivate(&priv); -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
