[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]
To obtain the IWDFDevice3 interface, drivers call IWDFDevice::QueryInterface.
The IWDFDevice3 interface has these methods.
|IWDFDevice3::AssignS0IdleSettingsEx||The AssignS0IdleSettingsEx method provides driver-supplied information that the framework uses when a device is idle and the system is in its working (S0) state.|
|IWDFDevice3::CreateInterrupt||The CreateInterrupt method creates a framework interrupt object.|
|IWDFDevice3::CreateWorkItem||The CreateWorkItem method creates a framework work-item object, which can subsequently be added to the framework’s work-item queue.|
|IWDFDevice3::GetHardwareRegisterMappedAddress||A driver calls GetHardwareRegisterMappedAddress to get the user-mode mapped address of the memory resource it earlier mapped using MapIoSpace.|
|IWDFDevice3::MapIoSpace||The MapIoSpace method maps the given physical address range to system address space and returns a pseudo base address.|
|IWDFDevice3::ReadFromHardware||The ReadFromHardware method is used internally by the framework. Do not use.|
|IWDFDevice3::UnmapIoSpace||The UnmapIoSpace method unmaps a specified range of physical addresses previously mapped by MapIoSpace method.|
|IWDFDevice3::WriteToHardware||The WriteToHardware method is used internally by the framework. Do not use.|
|End of support||Unavailable in UMDF 2.0 and later.|
|Minimum UMDF version||1.11|
