This function queues an update as part of a bulk operation. It will only modify a single document on the MongoDB server. This function does not execute the operation. To execute the entirety of the bulk operation call mongoc_bulk_operation_execute() <>.

This function is superseded by mongoc_bulk_operation_update_one_with_opts() <>.

• bulk: A mongoc_bulk_operation_t <>.
• selector: A bson_t <https://www.mongoc.org/libbson/current/bson_t.html> that selects which document to remove.
• document: A bson_t <https://www.mongoc.org/libbson/current/bson_t.html> containing the update document.
• upsert: true if an upsert should be performed.
