## SQLite C Interface

## Status Parameters for database connections

>     #define SQLITE_DBSTATUS_LOOKASIDE_USED     0
>     #define SQLITE_DBSTATUS_CACHE_USED         1
>     #define SQLITE_DBSTATUS_MAX                1   /* Largest defined DBSTATUS */

These constants are the available integer "verbs" that can be passed as the second argument to the sqlite3_db_status() interface.

New verbs may be added in future releases of SQLite. Existing verbs might be discontinued. Applications should check the return code from sqlite3_db_status() to make sure that the call worked. The sqlite3_db_status() interface will return a non-zero error code if a discontinued or unsupported verb is invoked.

SQLITE_DBSTATUS_LOOKASIDE_USED
  This parameter returns the number of lookaside memory slots currently checked out.

SQLITE_DBSTATUS_CACHE_USED
  This parameter returns the approximate number of of bytes of heap memory used by all pager caches associated with the database connection. The highwater mark associated with SQLITE_DBSTATUS_CACHE_USED is always 0.
