int sqlite3_db_status(sqlite3*, int op, int *pCur, int *pHiwtr, int resetFlg);
This interface is used to retrieve runtime status information about a single database connection. The first argument is the database connection object to be interrogated. The second argument is an integer constant, taken from the set of SQLITE_DBSTATUS options, that determines the parameter to interrogate. The set of SQLITE_DBSTATUS options is likely to grow in future releases of SQLite.
The current value of the requested parameter is written into *pCur and the highest instantaneous value is written into *pHiwtr. If the resetFlg is true, then the highest instantaneous value is reset back down to the current value.
The sqlite3_db_status() routine returns SQLITE_OK on success and a non-zero error code on failure.
