NdfCancelIncident function (ndfapi.h)

The NdfCancelIncident function is used to cancel unneeded functions which have been previously called on an existing incident.


HRESULT NdfCancelIncident(
  [in] NDFHANDLE      Handle


[in] Handle


Handle to the Network Diagnostics Framework incident. This handle should match the handle of an existing incident.

Return value


Possible return values include, but are not limited to, the following.

Return code Description
The operation succeeded.

Any result other than S_OK should be interpreted as an error.


Before using this API, an application must call an incident creation function such as NdfCreateWebIncident.

NdfCancelIncident is primarily used to cancel calls to functions such as NdfDiagnoseIncident or NdfRepairIncident which have been previously called, but are no longer needed. When NdfCancelIncident is called, NDF will stop the diagnosis/repair as soon as possible rather than calling the other functions (unless results have already been returned from those functions, in which case NdfCancelIncident will have no effect).

NdfCloseIncident should be used to close an incident once it has been resolved, as NdfCancelIncident does not actually close the incident itself.
