SYNOPSIS

          void
          mongoc_client_set_read_prefs (mongoc_client_t *client,
                                        const mongoc_read_prefs_t *read_prefs);

       Sets the default read preferences to use with future operations upon client.

       The global default is to read from the replica set primary.

       It  is  a  programming  error  to  call this function on a client from a mongoc_client_pool_t. For pooled
       clients, set the read preferences with the MongoDB URI instead.

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

PARAMETERS

       • client: A mongoc_client_t.

       • read_prefs: A mongoc_read_prefs_t.
