NAME

       mongoc_session_opts_set_default_transaction_opts                                         -
       mongoc_session_opts_set_default_transaction_opts()

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.
