# Function: sendSyncReadStatusMessage()

> **sendSyncReadStatusMessage**(`conversation`, `timestamp`): `Promise`\<[`RCResult`](../interfaces/RCResult.md)\<`void`\>\>

多端同步阅读状态

## Parameters

### conversation

[`IConversationIdentifier`](../interfaces/IConversationIdentifier.md)

会话信息

### timestamp

`number`

需要同步消息阅读的时间戳，可以在消息体中通过消息的 sendTime 获取

## Returns

`Promise`\<[`RCResult`](../interfaces/RCResult.md)\<`void`\>\>

## Description

由于未读消息数存储在本地，服务器不存未读消息数量。当用户多端登录时，需要同步未读消息数以保证多端未读数一致

## Example

多端同步阅读状态示例：
```ts
const conversation = {
 conversationType: RongIMLib.ConversationType.PRIVATE,
 targetId: 'targetId',
}
const timestamp = 1632728573423; // 阅读消息的 sendTime
const syncReadStatusRes = await RongIMLib.sendSyncReadStatusMessage(conversation, timestamp);
console.info('多端同步阅读状态：', syncReadStatusRes);
```
