# mongoc_database_set_read_prefs()

## Synopsis

    void
    mongoc_database_set_read_prefs (mongoc_database_t *database,
                                    const mongoc_read_prefs_t *read_prefs);

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

The global default is MONGOC_READ_PRIMARY: if the client is connected to a replica set it reads from the primary, otherwise it reads from the current MongoDB server.

Please see the MongoDB website for a description of Read Preferences.

## Parameters

- `database`: A mongoc_database_t.
- `read_prefs`: A mongoc_read_prefs_t.

Created using Sphinx 1.6.5, based on Sphinx Readable Theme.
