WDF_PNP_STATE enumeration (wudfddi_types.h)

  • Article

[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.]

The WDF_PNP_STATE enumeration contains values that identify the status of Plug and Play (PnP) for a device.

Syntax

typedef enum _WDF_PNP_STATE {
  WdfPnpStateInvalid,
  WdfPnpStateDisabled,
  WdfPnpStateFailed,
  WdfPnpStateRemoved,
  WdfPnpStateResourcesChanged,
  WdfPnpStateDontDisplayInUI,
  WdfPnpStateNotDisableable,
  WdfPnpStateMaximum
} WDF_PNP_STATE;

Constants

 
WdfPnpStateInvalid
The PnP state for the device is invalid.
WdfPnpStateDisabled

WdfPnpStateFailed
