DbEnv::appexit

#include <db_cxx.h> DbEnv::appexit Description The DbEnv::appexit method closes the initialized Berkeley DB subsystems, freeing any allocated resources and closing any underlying subsystems. In multi-threaded applications, only a single thread may call DbEnv::appexit. The DbEnv::appexit method either returns errno or throws an exception that encapsulates an errno on failure, and 0 on success. Errors If a fatal error occurs in Berkeley DB, the DbEnv::appexit method may fail and either return DB_RUNRECOVERY or throw an exception encapsulating DB_RUNRECOVERY, at which point all subsequent database calls will also fail in the same way. Methods marked as returning errno will, by default, throw an exception that encapsulates the error information. The default error behavior can be changed, see DbException. The DbEnv::appexit method may fail and throw an exception for any of the errors specified for the following Berkeley DB and C library functions: free(3), DbLockTab::close, DbLog::close, DbMpool::close, memset(3), strlen(3), and DbTxnMgr::close.
