 ## cl.multimodalinput.1 API错误信息返回方式变更
 
-如下原有接口使用业务逻辑返回值表示错误信息，不符合OpenHarmony接口错误码规范。从API9开始作以下变更，
-设备管理：三方接口，@ohos.multimodalInput.inputDevice.d.ts
+下列模块内部接口使用业务逻辑返回值表示错误信息，不符合OpenHarmony接口错误码规范。在API9进行变更。
+ - 输入设备管理模块：三方接口，@ohos.multimodalInput.inputDevice.d.ts
 
-按键订阅：系统接口，@ohos.multimodalInput.inputConsumer.d.ts
+ - 组合按键订阅模块：系统接口，@ohos.multimodalInput.inputConsumer.d.ts
 
-键鼠穿越：系统接口，@ohos.multimodalInput.inputDeviceCooperate.d.ts
+ - 键鼠穿越功能模块：系统接口，@ohos.multimodalInput.inputDeviceCooperate.d.ts
 
-按键注入：系统接口，@ohos.multimodalInput.inputEventClient.d.ts
+ - 按键注入模块：系统接口，@ohos.multimodalInput.inputEventClient.d.ts
 
-事件监听：系统接口，@ohos.multimodalInput.inputMonitor.d.ts
+ - 输入监听模块：系统接口，@ohos.multimodalInput.inputMonitor.d.ts
 
-指针事件：系统接口和三方接口，@ohos.multimodalInput.pointer.d.t
+ - 鼠标指针管理模块：系统接口和三方接口，@ohos.multimodalInput.pointer.d.t
 
-异步接口：通过AsyncCallback或Promise的error对象返回错误信息。
-
-同步接口：不涉及。
+以上模块中的异步接口变更为参数检查错误同步抛出，业务逻辑错误通过AsyncCallback或Promise的error对象抛出，同步接口不作变更。
