The following Db methods may be useful to you when managing DB databases:
Db::get_open_flags()
Returns the current open flags. It is an error to use this method on an unopened database.
#include <db_cxx.h> ... Db db(NULL, 0); u_int32_t open_flags; // Database open and subsequent operations omitted for clarity db.get_open_flags(&open_flags);
Db::remove()
Removes the specified database. If no value is given for the database parameter, then the entire file referenced by this method is removed.
Never remove a database that has handles opened for it. Never remove a file that contains databases with opened handles.
#include <db_cxx.h> ... Db db(NULL, 0); // Database open and subsequent operations omitted for clarity db.remove("mydb.db", // Database file to remove NULL, // Database to remove. This is // NULL so the entire file is // removed. 0); // Flags. None used.
Db::rename()
Renames the specified database. If no value is given for the database parameter, then the entire file referenced by this method is renamed.
Never rename a database that has handles opened for it. Never rename a file that contains databases with opened handles.
#include <db_cxx.h> ... Db db(NULL, 0); // Database open and subsequent operations omitted for clarity db.rename("mydb.db", // Database file to rename NULL, // Database to rename. This is // NULL so the entire file is // renamed. "newdb.db", // New database file name 0); // Flags. None used.
