# XTaskQueueRegistrationToken

コールバックの登録時に返される、登録を識別するためのトークンです。

## 構文

```cpp theme={null}
typedef struct XTaskQueueRegistrationToken {  
    uint64_t token;  
} XTaskQueueRegistrationToken  
```

### メンバー

*token*\
Type: uint64\_t

登録を識別するために、コールバックの登録時に返されるトークンです。

## 解説

`XTaskQueueRegistrationToken` は、タスク キューにコールバックを登録するときに返される *登録トークン* を表します。以前に登録したコールバックの登録を解除するときに、この登録トークンを使用します。登録トークンは、登録対象のコールバックのスコープ内でのみ一意です。

`XTaskQueueRegistrationToken` は、次の関数で使用されます:
