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.h> ... DB *dbp; u_int32_t open_flags; /* Database open and subsequent operations omitted for clarity */ dbp->get_open_flags(dbp, &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.h>
...
DB *dbp;
/* Database open and subsequent operations omitted for clarity */
dbp->remove(dbp, /* Database pointer */
"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.h>
...
DB *dbp;
/* Database open and subsequent operations omitted for clarity */
dbp->rename(dbp, /* Database pointer */
"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. */
