  RAWINPUTHEADER header;
  union {
    RAWMOUSE    mouse;
    RAWKEYBOARD keyboard;
    RAWHID      hid;
  } data;

Remarks

The handle to this structure is passed in the lParam parameter of WM_INPUT.

To get detailed information -- such as the header and the content of the raw input -- call GetRawInputData.

To read the RAWINPUT in the message loop as a buffered read, call GetRawInputBuffer.

To get device specific information, call GetRawInputDeviceInfo with the hDevice from RAWINPUTHEADER.

Raw input is available only when the application calls RegisterRawInputDevices with valid device specifications.
