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 handle creation 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 handle creation 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. */
