# mongoc_bulk_operation_update_many_with_opts()

## Synopsis

    bool
    mongoc_bulk_operation_update_many_with_opts (mongoc_bulk_operation_t *bulk,
                                                 const bson_t *selector,
                                                 const bson_t *document,
                                                 const bson_t *opts,
                                                 bson_error_t *error); /* OUT */

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().

Warning

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

## Parameters

- `bulk`: A mongoc_bulk_operation_t.

- `selector`: A `bson_t` that selects which documents to remove.

- `document`: A `bson_t` containing the update document.

- `error`: A `bson_error_t` any errors that may have occurred.

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

- `validate`: Construct a bitwise-or of all desired `bson_validate_flags_t`. Set to `false` to skip client-side validation of the provided BSON documents.

- `collation`: Configure textual comparisons. See Setting Collation Order, and the MongoDB Manual entry on Collation. Collation requires MongoDB 3.2 or later, otherwise an error is returned.

- `hint`: A document or string that specifies the index to use to support the query predicate.

- `upsert`: If true, insert a document if none match `selector`.

- `arrayFilters`: An array of filters specifying to which array elements an update should apply.

## Errors

Operation errors are propagated via mongoc_bulk_operation_execute(), while argument validation errors are reported by the `error` argument.

## Returns

Returns true on success, and false if there is a server or network error or if passed invalid arguments.
