Class Extension Properties
Windows Portable Devices supports the following class-extension properties.
| Property | VarType | Description |
| WPD_CLASS_EXTENSION_OPTIONS_SUPPORTED_CONTENT_TYPES | VT_UNKNOWN | A value that specifies the (superset) list of content types supported by the driver (similar to calling WPD_COMMAND_CAPABILITIES_GET_SUPPORTED_CONTENT_TYPES on WPD_FUNCTIONAL_CATEGORY_ALL). |
| WPD_CLASS_EXTENSION_OPTIONS_DONT_REGISTER_WPD_DEVICE_INTERFACE | VT_BOOL | A Boolean value that specifies whether the caller wants the WPD class extension library to register the WPD Device Class interface. If this value is true, the caller takes responsibility for registration. If this value is false, it indicates that the caller expects the class extension library to perform the registration. Most drivers should allow the class extension library to perform the registration. in the only exception are those cases where the registering of the WPD Device Class interface by the class extension library will cause adverse affects. |
