  sqlite3 *db,                    // Database handle 
  const char *zDb,                // Name of attached database (or NULL) 
  int eMode,                      // SQLITE_CHECKPOINT_* value 
  int *pnLog,                     // OUT: Size of WAL log in frames 
  int *pnCkpt                     // OUT: Total number of frames checkpointed 
);
