The Get4BRange method gets the 4-byte range of the device-specific property value.
Pointer to a LONG variable into which the method writes the minimum property value.
Pointer to a LONG variable into which the method writes the maximum property value.
Pointer to a LONG variable into which the method writes the stepping value between consecutive property values in the range *plMin to *plMax. If the difference between the maximum and minimum property values is d, and the range is divided into n steps (uniformly sized intervals), then the property can take n + 1 discrete values and the size of the step between consecutive values is d / n.
If the method succeeds, it returns S_OK. If it fails, possible return codes include, but are not limited to, the values shown in the following table.
| Return code | Description |
|---|---|
|
Pointer plMin, plMax, or plStepping is NULL. |
|
The property value is not a 32-bit signed or unsigned integer. For information about this macro, see the Windows SDK documentation. |
This method reports the range and step size for a property value that is a 32-bit signed or unsigned integer. These two data types are represented by VARENUM enumeration constants VT_I4 and VT_UI4, respectively. If the property value is not a 32-bit integer, then the method returns an error status code. For more information about VARENUM, see the Windows SDK documentation.
