Keyboard device constants, defined in Dinput.h, represent offsets within a keyboard device's data packet, a 256-byte array. The data at a given offset is associated with a keyboard key. Typically, these values will be used in the dwOfs member of the DIDEVICEOBJECTDATA, DIOBJECTDATAFORMAT or DIDEVICEOBJECTINSTANCE structures, or as indices when accessing data within the array using array notation.
The standard keyboard device constants are the following (in ascending order):
