The FwpmCalloutDeleteById0 function deletes a callout from the filter engine.
NTSTATUS FwpmCalloutDeleteById0( HANDLE engineHandle, UINT32 id );
A handle for an open session to the filter engine. A callout driver calls the FwpmEngineOpen0 function to open a session to the filter engine.
The run-time identifier for the callout that is being deleted from the filter engine. This must be the run-time identifier that was returned when the callout driver called the FwpmCalloutAdd0 function to add the callout to the filter engine.
The FwpmCalloutDeleteById0 function returns one of the following NTSTATUS codes.
||The callout was successfully deleted from the filter engine.|
||One or more filters in the filter engine specify the callout for the filter's action.|
||There is not a callout in the filter engine that matches the run-time identifier specified in the id parameter.|
||An error occurred.|
A callout driver calls the FwpmCalloutDeleteById0 function to delete a callout from the filter engine, using the run-time identifier to identify the callout to be deleted.
Callout drivers do not typically delete their callouts from the filter engine. In most situations, this is handled by a user-mode Windows Filtering Platform management application.
A callout can be deleted from the filter engine only if there are no filters in the filter engine that specify the callout for the filter's action.
