The WDF_INTERRUPT_POLARITY enumeration type is used to specify an interrupt signal's polarity.
Syntax
typedef enum _WDF_INTERRUPT_POLARITY {
WdfInterruptPolarityUnknown = 0,
WdfInterruptActiveHigh,
WdfInterruptActiveLow
} WDF_INTERRUPT_POLARITY, *PWDF_INTERRUPT_POLARITY;
Constants
WdfInterruptPolarityUnknownValue: 0 The interrupt signal's polarity is unknown. |
WdfInterruptActiveHighThe interrupt signal is active when it is high. |
WdfInterruptActiveLowThe interrupt signal is active when it is low. |
Remarks
The WDF_INTERRUPT_POLARITY enumeration type is used to specify a member of the WDF_INTERRUPT_INFO structure.
