WDF_INTERRUPT_POLARITY enumeration

[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       = 1,
  WdfInterruptActiveLow        = 2
} WDF_INTERRUPT_POLARITY, *PWDF_INTERRUPT_POLARITY;

Constants

WdfInterruptPolarityUnknown

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.

Requirements

Minimum KMDF version

1.0

Minimum UMDF version

2.0
