void (*paniccall)(DB_ENV *, int errval));
Errors can occur in the Berkeley DB library where the only solution is to shut
down the application and run recovery (for example, if Berkeley DB is unable
to allocate heap memory). In these cases, the value DB_RUNRECOVERY
is returned by Berkeley DB.
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_ENV->set_paniccall and DB->set_paniccall methods
are used to specify functions to be called when
DB_RUNRECOVERY is about to be returned from a Berkeley DB interface.
When called, the dbenv argument will be a reference to the
current environment, and the errval argument is the error value
that would have been returned to the calling function.
The DB_ENV->set_paniccall interface may be called at any time during the life of
The DB_ENV->set_paniccall method returns a non-zero error value on failure and 0 on success.
