NAME

       mongoc_session_opts_new - mongoc_session_opts_new()

SYNOPSIS

          mongoc_session_opt_t *
          mongoc_session_opts_new (void);

       Start a session with mongoc_client_start_session, use the session for a sequence of operations, then free
       it with mongoc_client_session_destroy(). A session must be freed before the mongoc_client_t it came from.

       By  default,  sessions  are causally consistent. To disable causal consistency, before starting a session
       create       a       mongoc_session_opt_t       with       mongoc_session_opts_new()       and       call
       mongoc_session_opts_set_causal_consistency(), then free the struct with mongoc_session_opts_destroy.

       Unacknowledged   writes   are  not  causally  consistent.  If  you  execute  a  write  operation  with  a
       mongoc_write_concern_t on which you have called mongoc_write_concern_set_w with a value of 0,  the  write
       does not participate in causal consistency.

       A  mongoc_client_session_t  must  be  used  by  only  one  thread  at  a  time.  Due  to session pooling,
       mongoc_client_start_session may return a session that has been idle for some time  and  is  about  to  be
       closed  after  its idle timeout. Use the session within one minute of acquiring it to refresh the session
       and avoid a timeout.

       See the example code for mongoc_session_opts_set_causal_consistency.
