In these cases, it is also often simpler to shut down the application when such errors occur rather than to try to gracefully return up the stack. The DB→set_paniccall function is used to specify a function to be called when DB_RUNRECOVERY is about to be returned from a Berkeley DB method. When called, the dbenv argument will be a reference ...
