WM_INPUT message
Sent to the window that is getting raw input.
A window receives this message through its WindowProc function.
#define WM_INPUT 0x00FF
Parameters
- wParam
-
The input code. This parameter can be one of the following values.
Value Meaning - RIM_INPUT
- 0
Input occurred while the application was in the foreground. The application must call DefWindowProc so the system can perform cleanup.
- RIM_INPUTSINK
- 1
Input occurred while the application was not in the foreground. The application must call DefWindowProc so the system can perform the cleanup.
- lParam
-
A handle to the RAWINPUT structure that contains the raw input from the device.
Return value
If an application processes this message, it should return zero.
Remarks
To get the wParam value, use the GET_RAWINPUT_CODE_WPARAM macro.
Note that lParam has the handle to the RAWINPUT structure, not a pointer to it. To get the raw data, use the handle in the call to GetRawInputData.
Raw input is available only when the application calls RegisterRawInputDevices with valid device specifications
