# mongoc_database_set_read_concern()

## Synopsis

    void
    mongoc_database_set_read_concern (mongoc_database_t *database,
                                      const mongoc_read_concern_t *read_concern);

This function sets the read concern to use on operations performed with `database`. Collections created with mongoc_database_get_collection() after this call will inherit this read concern.

The default read concern is empty: No readConcern is sent to the server unless explicitly configured.

## Parameters

- `database`: A mongoc_database_t.

- `read_concern`: A mongoc_read_concern_t.
