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. Once 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.
