writeConcern
: Construct a mongoc_write_concern_t and use mongoc_write_concern_append() to add the write concern toopts
. See the example code for mongoc_client_write_command_with_opts().sessionId
: First, construct a mongoc_client_session_t with mongoc_client_start_session(). You can begin a transaction with mongoc_client_session_start_transaction(), optionally with a mongoc_transaction_opt_t that overrides the options inherited fromcollection
, and use mongoc_client_session_append() to add the session toopts

: To target a specific server, include an int32 “serverId” field. Obtain the id by calling mongoc_client_select_server(), then mongoc_server_description_id() on its return value.
