# mongoc\_client\_pool\_set\_server\_api(3)

## SYNOPSIS

```
bool
mongoc_client_pool_set_server_api (mongoc_client_pool_t *pool,
                                   const mongoc_server_api_t *api,
                                   bson_error_t *error);
```

Set the API version to use for clients created through **pool**. Once the API version is set on a pool, it may not be changed to a new value. Attempting to do so will cause this method to fail and set **error**.

## PARAMETERS

- •

  **pool**: A *mongoc\_client\_pool\_t*.

- •

  **api**: A *mongoc\_server\_api\_t*.

- •

  **error**: A *bson\_error\_t*.

## RETURNS

True if the version was successfully set, false if not. On failure, **error** will be set.
