IWDFDevice3 interface (wudfddi.h)
[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.
Inheritance
The IWDFDevice3 interface inherits from IWDFDevice2. IWDFDevice3 also has these types of members:
- Methods
Methods
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 frameworkâs 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. |
