WDF_INTERRUPT_PRIORITY enumeration (wdfinterrupt.h)
[Applies to KMDF and UMDF]
The WDF_INTERRUPT_PRIORITY enumeration type identifies relative priorities for device interrupts.
Syntax
typedef enum _WDF_INTERRUPT_PRIORITY {
WdfIrqPriorityUndefined = 0,
WdfIrqPriorityLow,
WdfIrqPriorityNormal,
WdfIrqPriorityHigh
} WDF_INTERRUPT_PRIORITY, *PWDF_INTERRUPT_PRIORITY;
Constants
WdfIrqPriorityUndefined Value: 0 The relative priority of a device's interrupt is undefined. |
WdfIrqPriorityLow The device's interrupt has a relatively low priority, typically because the interrupt does not have to be serviced immediately. |
WdfIrqPriorityNormal The device's interrupt priority is neither relatively low nor relatively high. |
WdfIrqPriorityHigh The device's interrupt has a relatively high priority, typically because the interrupt must be serviced immediately. |
Remarks
The WDF_INTERRUPT_PRIORITY enumeration type is used as input to the WdfInterruptSetPolicy method.
