+# GetRawInputDevices
+Allows PresentationHost.exe to discover the raw input devices (Human Interface Devices) that the host application is interested in.  
+  
+## Syntax  
+  
+```cpp  
+HRESULT GetRawInputDevices( [out] IEnumRAWINPUTDEVICE **ppEnum );  
+```  
+  
+## Parameters  
+ `ppEnum`  
+  
+ [out] A pointer to an [IEnumRAWINPUTDEVICE](ienumrawinputdevice.md) for enumerating the raw input devices.  
+  
+## Property Value/Return Value  
+ HRESULT:  
+  
+ S_OK - [IEnumRAWINPUTDEVICE](ienumrawinputdevice.md) will only be used by PresentationHost.exe if S_OK is returned.  
+  
+ E_NOTIMPL  
+  
+## Remarks  
+ Raw input devices are the set of input devices that includes keyboards, mice, and less traditional devices like remote controls.  
+  
+ Once the list of raw input devices has been retrieved, PresentationHost.exe registers with the devices to receive WM_INPUT notification messages.
