# mongoc_collection_create_bulk_operation_with_opts()

## Synopsis

    mongoc_bulk_operation_t *
    mongoc_collection_create_bulk_operation_with_opts (
       mongoc_collection_t *collection,
       const bson_t *opts) BSON_GNUC_WARN_UNUSED_RESULT;

## Parameters

- `collection`: A mongoc_collection_t.

`opts` may be NULL or a BSON document with additional command options:

- `writeConcern`: Construct a mongoc_write_concern_t and use mongoc_write_concern_append() to add the write concern to `opts`. See the example code for mongoc_client_write_command_with_opts().
- `ordered`: set to `false` to attempt to insert all documents, continuing after errors.
- `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 from `collection`, and use mongoc_client_session_append() to add the session to `opts`. See the example code for mongoc_client_session_t.
