IWDFInterrupt 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.]
This interface exposes an interrupt object.
The IWDFInterrupt interface inherits from IWDFObject. IWDFInterrupt also has these types of members:
The IWDFInterrupt interface has these methods.
The AcquireInterruptLock method begins a code sequence that executes while holding an interrupt object's lock.
The Disable method disables a specified device interrupt by calling the driver's OnInterruptDisable callback function.
The Enable method enables a specified device interrupt by calling the driver's OnInterruptEnable callback function.
The GetDevice method returns the framework device object interface for this interrupt object.
The GetInfo method retrieves information about a specified interrupt.
The QueueWorkItemForIsr method queues a work item to process interrupt-related work outside of the interrupt service routine.
The ReleaseInterruptLock method ends a code sequence that executes while holding an interrupt object's lock.
The SetExtendedPolicy method specifies the interrupt priority, processor affinity, affinity policy, and processor group for a specified interrupt.
The SetPolicy method specifies the interrupt priority, processor affinity, and affinity policy for a specified interrupt.
The TryToAcquireInterruptLock method acquires the interrupt lock if no other thread has already acquired it.
|End of support||Unavailable in UMDF 2.0 and later.|
|Minimum UMDF version||1.11|
