# mongoc\_bulk\_operation\_set\_hint(3)

**WARNING:**

Deprecated since version 1.28.0: Use *mongoc\_bulk\_operation\_set\_server\_id()* instead.

## SYNOPSIS

```
void
mongoc_bulk_operation_set_hint (mongoc_bulk_operation_t *bulk, uint32_t server_id);
```

## PARAMETERS

- •

  **bulk**: A *mongoc\_bulk\_operation\_t*.

- •

  **server\_id**: An opaque id identifying the server to use.

## DESCRIPTION

Specifies which server to use for the operation. This function has an effect only if called before *mongoc\_bulk\_operation\_execute()*.

(The function name includes the old term "hint" for the sake of backward compatibility, but we now call this number a "server id".)

Use **mongoc\_bulk\_operation\_set\_hint** only for building a language driver that wraps the C Driver. When writing applications in C, leave the server id unset and allow the driver to choose a suitable server for the bulk operation.
