SYNOPSIS

13       Start a session with mongoc_client_start_session, use the session for a
14       sequence of operations and multi-document transactions,  then  free  it
15       with   mongoc_client_session_destroy().  Any  mongoc_cursor_t  or  mon‐
16       goc_change_stream_t using a session must be destroyed before  the  ses‐
17       sion,  and  a  session  must be destroyed before the mongoc_client_t it
18       came from.
19
20       By default, sessions are causally consistent. To disable causal consis‐
21       tency,  before  starting  a  session create a mongoc_session_opt_t with
22       mongoc_session_opts_new() and call  mongoc_session_opts_set_causal_con‐
23       sistency(), then free the struct with mongoc_session_opts_destroy.
24
25       Unacknowledged writes are prohibited with sessions.
26
27       A  mongoc_client_session_t  must  be used by only one thread at a time.
28       Due to session pooling, mongoc_client_start_session may return  a  ses‐
29       sion  that  has been idle for some time and is about to be closed after
30       its idle timeout. Use the session within one minute of acquiring it  to
31       refresh the session and avoid a timeout.

33       See the example code for mongoc_session_opts_set_causal_consistency.
