The DIPROPRANGE structure contains information about the range of an object within a device. This structure is used with the DIPROP_RANGE flag set in the IDirectInputDevice::GetProperty and IDirectInputDevice::SetProperty methods.
typedef struct DIPROPRANGE {
DIPROPHEADER diph;
LONG lMin;
LONG lMax;
} DIPROPRANGE, *LPDIPROPRANGE;
typedef const DIPROPRANGE *LPCDIPROPRANGE;
Members
diph
A DIPROPHEADER structure that must be initialized as follows:
| dwSize | sizeof(DIPROPRANGE) |
| dwHeaderSize | sizeof(DIPROPHEADER) |
| dwObj | Identifier of the object whose range is being retrieved or set. |
| dwHow | How the dwObj member should be interpreted. |
lMin
The lower limit of the range, inclusive. If the range of the device is unrestricted, this value will be DIPROPRANGE_NOMIN when the IDirectInputDevice::GetProperty method returns.
lMax
The upper limit of the range, inclusive. If the range of the device is unrestricted, this value will be DIPROPRANGE_NOMAX when the IDirectInputDevice::GetProperty method returns.
Remarks
The range values for devices whose ranges are unrestricted will wrap around.
