IPnpCallbackHardwareInterrupt interface

The IPnpCallbackHardwareInterrupt interface supports interrupt-related Plug and Play and power management callback methods.

When to implement

A driver implements this interface and registers it when it calls the IWDFDriver::CreateDevice method to create a device object.

Members

The IPnpCallbackHardwareInterrupt interface inherits from the IUnknown interface. IPnpCallbackHardwareInterrupt also has these types of members:

Methods

The IPnpCallbackHardwareInterrupt interface has these methods.

MethodDescription
OnD0EntryPostInterruptsEnabled

A driver's OnD0EntryPostInterruptsEnabled event callback function performs device-specific operations that are required when the driver enables the device's hardware interrupts.

OnD0ExitPreInterruptsDisabled

A driver's OnD0ExitPreInterruptsDisabled event callback function performs device-specific operations that are required before the driver disables the device's hardware interrupts.
