  • Article

[Applies to KMDF and UMDF]

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

 
WdfInterruptPolarityUnknown
Value: 0
The interrupt signal's polarity is unknown.
WdfInterruptActiveHigh
The interrupt signal is active when it is high.
WdfInterruptActiveLow
The 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.
