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.
