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
WdfIrqPriorityUndefinedValue: 0 The relative priority of a device's interrupt is undefined. |
WdfIrqPriorityLowThe device's interrupt has a relatively low priority, typically because the interrupt does not have to be serviced immediately. |
WdfIrqPriorityNormalThe device's interrupt priority is neither relatively low nor relatively high. |
WdfIrqPriorityHighThe 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.
