_WDF_INTERRUPT_POLARITY enumeration (wdfinterrupt.h)

Description

[Applies to KMDF and UMDF]

The WDF_INTERRUPT_POLARITY enumeration type is used to specify an interrupt signal's polarity.

Constants

WdfInterruptPolarityUnknown: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.

_WDF_INTERRUPT_POLARITY enumeration (wudfinterrupt.h)

Description

[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]
