14 Set the default options for transactions started with this session. The
15 txn_opts argument is copied and can be freed after calling this func‐
16 tion.
17
18 When a session is first created with mongoc_client_start_session, it
19 inherits from the client the read concern, write concern, and read
20 preference with which to start transactions. Each of these fields can
21 be overridden independently. Create a mongoc_transaction_opt_t with
22 mongoc_transaction_opts_new, and pass a non-NULL option to any of the
23 mongoc_transaction_opt_t setter functions:
24
25 • mongoc_transaction_opts_set_read_concern
26
27 • mongoc_transaction_opts_set_write_concern
28
29 • mongoc_transaction_opts_set_read_prefs
30
31 Pass the resulting transaction options to mongoc_session_opts_set_de‐
32 fault_transaction_opts. Each field set in the transaction options over‐
33 rides the inherited client configuration. There is an opportunity to
34 override each one of these fields again by passing a mongoc_transac‐
35 tion_opt_t to mongoc_client_session_start_transaction.
36
38 • opts: A mongoc_session_opt_t.
39
40 • txn_opts: A mongoc_transaction_opt_t.
