Berkeley DB: Dbc::close
Dbc::close
|
 
|
#include <db_cxx.h>
int
Dbc::close(void);
Description
The Dbc::close method discards the cursor.
It is possible for the Dbc::close method to return
DB_LOCK_DEADLOCK, signaling that any enclosing transaction should
be aborted. If the application is already intending to abort the
transaction, this error should be ignored, and the application should
proceed.
After Dbc::close has been called, regardless of its return, the
cursor handle may not be used again.
The Dbc::close method either returns a non-zero error value or throws an exception that
encapsulates a non-zero error value on failure, and returns 0 on success.
Errors
The Dbc::close method may fail and throw an exception or return a non-zero error for the following conditions:
- DB_LOCK_DEADLOCK
- The operation was selected to resolve a deadlock.
- EINVAL
- An invalid flag value or parameter was specified.
The cursor was previously closed.
The Dbc::close method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
If a catastrophic error has occurred, the Dbc::close method may fail and either
return DB_RUNRECOVERY or throw an exception encapsulating
DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail
in the same way.
