       • client: A mongoc_client_t.

       • read_concern: A mongoc_read_concern_t.

          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 mongoc_client_pool_t. For pooled
       clients, set the read concern with the MongoDBURI instead.
