Artigo
11/09/2023

Retrieves a device based on its DeviceID.

Syntax

HRESULT FindDeviceFromId(  
         const APP_LOCAL_DEVICE_ID* value,  
         IGameInputDevice** device  
)

Parameters

value _In_
Type: APP_LOCAL_DEVICE_ID*

System generated ID for the device.

device _COM_Outptr_
Type: IGameInputDevice**

The returned device.

Return value

Type: HRESULT

Function result.

Remarks

Once obtained, the IGameInputDevice instance can be used as a filter in the polling APIs like IGameInput::GetCurrentReading, or event-based APIs like IGameInput::RegisterReadingCallback (to retrieve input), or used directly to access device-specific information and features. If the provided identifier cannot be matched with any known GameInput device objects, the GetDeviceFrom* methods return a NULL pointer. These methods interrogate local state within the calling process and return quickly, so they are safe to call from time sensitive contexts.
