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.

Inheritance

The IWDFInterrupt interface inherits from IWDFObject. IWDFInterrupt also has these types of members:

• Methods

Methods

The IWDFInterrupt interface has these methods.

IWDFInterrupt::AcquireInterruptLock The AcquireInterruptLock method begins a code sequence that executes while holding an interrupt object's lock.
IWDFInterrupt::Disable The Disable method disables a specified device interrupt by calling the driver's OnInterruptDisable callback function.
IWDFInterrupt::Enable The Enable method enables a specified device interrupt by calling the driver's OnInterruptEnable callback function.
IWDFInterrupt::GetDevice The GetDevice method returns the framework device object interface for this interrupt object.
IWDFInterrupt::GetInfo The GetInfo method retrieves information about a specified interrupt.
IWDFInterrupt::QueueWorkItemForIsr The QueueWorkItemForIsr method queues a work item to process interrupt-related work outside of the interrupt service routine.
IWDFInterrupt::ReleaseInterruptLock The ReleaseInterruptLock method ends a code sequence that executes while holding an interrupt object's lock.
IWDFInterrupt::SetExtendedPolicy The SetExtendedPolicy method specifies the interrupt priority, processor affinity, affinity policy, and processor group for a specified interrupt.
IWDFInterrupt::SetPolicy The SetPolicy method specifies the interrupt priority, processor affinity, and affinity policy for a specified interrupt.
IWDFInterrupt::TryToAcquireInterruptLock The TryToAcquireInterruptLock method acquires the interrupt lock if no other thread has already acquired it.
