# ToCoNet\_vDebugLevel()

## 解説

TWELITE NET のデバッグ出力レベルを変更する。

レベルは 0 が出力なしで、最大5です。大きくなればなるほど、多くのメッセージが出力されます。

{% hint style="warning" %}
[`ToCoNet_vDebugInit()`](/twelite-net-api-ref/twelite-net-guan-shu/toconet_vdebuginit.md) により初期化します。

[Makefile](/twelite-sdk-howto/birudonitsuite/makefile-nitsuite.md) にて`TOCONET_DEBUG`を`1`に設定します。
{% endhint %}

{% hint style="danger" %}
デバッグメッセージは TWELITE NET の内部開発向けで、出力書式等については開示しません。問題の解析等を行う際に、お客様に出力をご連絡いただく場合があります。
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://sdk.twelite.info/twelite-net-api-ref/twelite-net-guan-shu/toconet_vdebuglevel.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
