Note FwpsFlowAbort0 is a specific version of FwpsFlowAbort. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.
flowId [in]A run-time identifier that specifies the data flow that is being aborted. The run-time identifier for a data flow is provided to a callout driver through the FWPS_METADATA_FIELD_FLOW_HANDLE metadata value that the filter engine provided to the callout driver's classifyFn callout function.
The FwpsFlowAbort0 function returns one of the following NTSTATUS codes.
| Return code | Description |
|---|---|
| STATUS_SUCCESS | The flow was aborted. |
| Other status codes | An error occurred. |
A callout driver can call the FwpsFlowAbort0 function to abort a data flow. The filter engine calls the flowDeleteFn callout function when the flow is terminated so that the callout driver can clean up the context associated with the flow.
