```ts
function sqlite3_extended_result_codes(
  deps: SqliteWasmDep,
): (db: SqliteDbPtr, onoff: number) => SqliteResultCode;
```

Defined in: [packages/sqlite-wasm/src/CApi.ts:1330](https://github.com/evoluhq/evolu/blob/bc4578a260dd15d5bbf94b83765ca05984d194cb/packages/sqlite-wasm/src/CApi.ts#L1330)

Enables extended result codes for the connection when onoff is non-zero and
disables them otherwise. They are disabled by default, and
[sqlite3\_extended\_errcode](https://evolu.dev/docs/api-reference/sqlite-wasm/c-api/functions/sqlite3_extended_errcode) returns them regardless.

Wasm type `i(ii)`. Signature `["sqlite3_extended_result_codes", "int",
"sqlite3*", "int"]` from SQLite's table.
