PNP_VETO_TYPE enumeration (cfg.h)

  • Article

If the PnP manager rejects a request to perform an operation, the PNP_VETO_TYPE enumeration is used to identify the reason for the rejection.

Syntax

typedef enum _PNP_VETO_TYPE {
  PNP_VetoTypeUnknown,
  PNP_VetoLegacyDevice,
  PNP_VetoPendingClose,
  PNP_VetoWindowsApp,
  PNP_VetoWindowsService,
  PNP_VetoOutstandingOpen,
  PNP_VetoDevice,
  PNP_VetoDriver,
  PNP_VetoIllegalDeviceRequest,
  PNP_VetoInsufficientPower,
  PNP_VetoNonDisableable,
  PNP_VetoLegacyDriver,
  PNP_VetoInsufficientRights,
  PNP_VetoAlreadyRemoved
} PNP_VETO_TYPE, *PPNP_VETO_TYPE;

Constants

 
PNP_VetoTypeUnknown
The specified operation was rejected for an unknown reason.
PNP_VetoLegacyDevice
The device does not support the specified PnP operation.
PNP_VetoPendingClose
The specified operation cannot be completed because of a pending close operation.
PNP_VetoWindowsApp
A Microsoft Win32 application vetoed the specified operation.
PNP_VetoWindowsService
A Win32 service vetoed the specified operation.
PNP_VetoOutstandingOpen
The requested operation was rejected because of outstanding open handles.
PNP_VetoDevice
The device supports the specified operation, but the device rejected the operation.
PNP_VetoDriver
The driver supports the specified operation, but the driver rejected the operation.
PNP_VetoIllegalDeviceRequest
The device does not support the specified operation.
PNP_VetoInsufficientPower
There is insufficient power to perform the requested operation.
PNP_VetoNonDisableable
The device cannot be disabled.
PNP_VetoLegacyDriver
The driver does not support the specified PnP operation.
PNP_VetoInsufficientRights
The caller has insufficient privileges to complete the operation.

Remarks

Text strings are associated with most of the veto types, and a function that receives a veto type value can typically request to also receive the value's associated text string. The following table identifies the text string associated with each value.

pVeto type value Text String
PNP_VetoTypeUnknown None.
PNP_VetoLegacyDevice A device instance path.
PNP_VetoPendingClose A device instance path.
PNP_VetoWindowsApp An application module name.
PNP_VetoWindowsService A Windows service name.
PNP_VetoOutstandingOpen A device instance path.
PNP_VetoDevice A device instance path.
PNP_VetoDriver A driver name.
PNP_VetoIllegalDeviceRequest A device instance path.
PNP_VetoInsufficientPower None.
PNP_VetoNonDisableable A device instance path.
PNP_VetoLegacyDriver A Windows service name.
