PNP_VETO_TYPE enumeration
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_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.

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 |
