SYNOPSIS

          void
          mongoc_session_opts_set_default_transaction_opts (
             mongoc_session_opt_t *opts, const mongoc_transaction_opt_t *txn_opts);

       Set  the  default options for transactions started with this session. The txn_opts argument is copied and
       can be freed after calling this function.

       When a session is first created with mongoc_client_start_session(), it inherits from the client the  read
       concern, write concern, and read preference with which to start transactions. Each of these fields can be
       overridden  independently. Create a mongoc_transaction_opt_t with mongoc_transaction_opts_new(), and pass
       a non-NULL option to any of the mongoc_transaction_opt_t setter functions:

       • mongoc_transaction_opts_set_read_concern()

       • mongoc_transaction_opts_set_write_concern()

       • mongoc_transaction_opts_set_read_prefs()

       Pass the resulting transaction options to mongoc_session_opts_set_default_transaction_opts(). Each  field
       set  in  the transaction options overrides the inherited client configuration. There is an opportunity to
       override   each   one   of   these   fields   again   by   passing    a    mongoc_transaction_opt_t    to
       mongoc_client_session_start_transaction().

PARAMETERS

       • opts: A mongoc_session_opt_t.

       • txn_opts: A mongoc_transaction_opt_t.
