DIPROPRANGE Structure
typedef struct DIPROPRANGE { DIPROPHEADER diph; LONG lMin; LONG lMax; } DIPROPRANGE, *LPDIPROPRANGE;
Members
- diph
- DIPROPHEADER structure.
- lMin
- Lower limit of the range. If the range of the device is unrestricted, this value is DIPROPRANGE_NOMIN when the IDirectInputDevice8::GetProperty method returns.
- lMax
- Upper limit of the range. If the range of the device is unrestricted, this value is DIPROPRANGE_NOMAX when the IDirectInputDevice8::GetProperty method returns.
The diph member must be initialized as follows:
| Member | Value |
|---|---|
| dwSize | sizeof(DIPROPRANGE) |
| dwHeaderSize | sizeof(DIPROPHEADER) |
| dwObj | If the dwHow member is DIPH_DEVICE, this member must be 0. If the dwHow member is DIPH_BYID, this member must be the identifier for the object whose property setting is to be set or retrieved. If the dwHow member is DIPH_BYOFFSET, this member must be a data format offset for the object whose property setting is to be set or retrieved. For example, if the c_dfDIMouse data format is selected, it must be one of the DIMOFS_* values.Identifier of the object whose property is being retrieved or set. If the dwHow member is DIPH_BYUSAGE, the device must be a Human Interface Device (human interface device). The device object will be identified by the HID usage page and usage values in packed form. |
| dwHow | Specifies how the dwObj member should be interpreted. See the preceding description of the dwObj member for details. |
The range values for devices whose ranges are unrestricted wraparound.
