Mouse device constants, defined in Dinput.h, represent offsets within a mouse device's data packet, the DIMOUSESTATE structure. The data at a given offset is associated with a device object (button or axis). Typically, these values will be used in the dwOfs member of the DIDEVICEOBJECTDATA, DIOBJECTDATAFORMAT or DIDEVICEOBJECTINSTANCE structures.
The mouse device constants are the following:
| DIMOFS_BUTTON0 | Offset of the data representing the state of mouse button 0. |
| DIMOFS_BUTTON1 | Offset of the data representing the state of mouse button 1. |
| DIMOFS_BUTTON2 | Offset of the data representing the state of mouse button 2. |
| DIMOFS_BUTTON3 | Offset of the data representing the state of mouse button 3. |
| DIMOFS_X | Offset of the data representing the mouse's position on the x-axis. |
| DIMOFS_Y | Offset of the data representing the mouse's position on the y-axis. |
| DIMOFS_Z | Offset of the data representing the mouse's position on the z-axis. |
