:man_page: mongoc_client_set_read_concern
mongoc_client_set_read_concern()
================================
Synopsis
--------
.. code-block:: c
void
mongoc_client_set_read_concern (mongoc_client_t *client,
const mongoc_read_concern_t *read_concern);
Sets the read concern for the client. This only affects future operations, collections, and databases inheriting from ``client``.
The default read concern is MONGOC_READ_CONCERN_LEVEL_LOCAL. This is the correct read concern for the great majority of applications.
It is a programming error to call this function on a client from a :symbol:`mongoc_client_pool_t`. For pooled clients, set the read concern with the :ref:`MongoDB URI <mongoc_uri_t_read_concern_options>` instead.
Parameters
----------
* ``client``: A :symbol:`mongoc_client_t`.
* ``read_concern``: A :symbol:`mongoc_read_concern_t`.
