       • bulk: A mongoc_bulk_operation_t.

       • selector: A bson_t that selects which documents to remove.

       • document: A bson_t containing the update document.

       • upsert: true if an upsert should be performed.

          void
          mongoc_bulk_operation_update (mongoc_bulk_operation_t *bulk,
                                        const bson_t *selector,

       This  function  queues  an  update  as  part of a bulk operation. This does not execute the operation. To
       execute the entirety of the bulk operation call mongoc_bulk_operation_execute().

       document MUST only contain fields whose key starts with $. See the update document specification for more
       details.

       This     function     is     superseded     by      mongoc_bulk_operation_update_one_with_opts()      and
       mongoc_bulk_operation_update_many_with_opts().
