Berkeley DB: DB_ENV->set_recovery_init
DB_ENV->set_recovery_init
|
 
|
#include <db.h>
int
DB_ENV->set_recovery_init(DB_ENV *,
int (*db_recovery_init_fcn)(DB_ENV *));
Description
Applications installing application-specific recovery functions need
to be called before Berkeley DB performs recovery so they may add their recovery
functions to Berkeley DB's.
The DB_ENV->set_recovery_init function supports this functionality. The
db_recovery_init_fcn function must be declared with one
argument, a reference to the enclosing Berkeley DB environment. This
function will be called after the DB_ENV->open has been called,
but before recovery is started.
If the db_recovery_init_fcn function returns a non-zero value,
no recovery will be performed, and DB_ENV->open will return the same
value to its caller.
The DB_ENV->set_recovery_init interface may be used only to configure Berkeley DB before
the DB_ENV->open interface is called.
The DB_ENV->set_recovery_init function returns a non-zero error value on failure and 0 on success.
Errors
The DB_ENV->set_recovery_init function may fail and return a non-zero error for the following conditions:
- EINVAL
- An invalid flag value or parameter was specified.
Called after DB_ENV->open was called.
The DB_ENV->set_recovery_init function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
If a catastrophic error has occurred, the DB_ENV->set_recovery_init function may fail and return
DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail
in the same way.
