This section describes Windows Filtering Platform (WFP) functions that are called out by callout drivers.

In This Section

• FwpsAllocateCloneNetBufferList0
  Allocates a clone NET_BUFFER_LIST structure of an existing NET_BUFFER_LIST structure.

• FwpsAllocateNetBufferAndNetBufferList0
  Allocates a new NET_BUFFER_LIST structure.

• FwpmBfeStateGet0
  Retrieves the current state of the WFP Filter Engine.

• FwpmBfeStateSubscribeChanges0
  Registers a callback function that is called whenever there is a change to the state of the filter engine.

• FwpmBfeStateUnsubscribeChanges0
  Unregisters a callback function that was previously registered by calling the FwpmBfeStateSubscribeChanges0 function.

• FwpsCalloutRegister0
  Registers a callout with the filter engine.

• FwpsCalloutUnregisterById0
  Unregisters a callout from the filter engine.

• FwpsCalloutUnregisterByKey0
  Unregisters a callout from the filter engine.

• FwpsClassifyOptionSet0
  Called by a callout filter's classifyFn function to specify additional information that affects the characteristics of permitted filtering operations.

• FwpsCloneStreamData0
  Allocates a clone of an existing FWPS_STREAM_DATA0**data stream.

• FwpsCompleteOperation0
  Resumes packet processing that was suspended pending completion of another operation.

• FwpsConstructIpHeaderForTransportPacket0
  Called by a callout to construct a new IP header or rebuild an existing IP packet header for one net buffer.

• FwpsCopyStreamDataToBuffer0
  Copies stream data to a buffer.

• FwpsDereferenceNetBufferList0
  Decrements the reference count for a NET_BUFFER_LIST structure that a callout driver had obtained earlier by using the FwpsReferenceNetBufferList0 function.

• FwpsDiscardClonedStreamData0
  Frees the memory buffer that was allocated by the FwpsCloneStreamData0 function.

• FwpsFlowAssociateContext0
  Associates a callout driver-defined context with a data flow.

• FwpsFlowRemoveContext0
  Removes a previously associated context from a data flow.

• FwpsFreeCloneNetBufferList0
  Frees a clone NET_BUFFER_LIST structure that was previously allocated by a call to the FwpsAllocateCloneNetBufferList0 function.

• FwpsFreeNetBufferList0
  Frees a NET_BUFFER_LIST structure that was previously allocated by a call to the FwpsAllocateNetBufferAndNetBufferList0 function.

• FwpsGetPacketListSecurityInformation0
  Retrieves information associated with a packet list.

• FwpsInjectForwardAsync0
  Injects packet data into the forwarding data path.

• FwpsInjectionHandleCreate0
  Creates a handle that can be used by packet injection functions to insert packet or stream data into the TCP/IP network stack, and by the FwpsQueryPacketInjectionState0 function to query the packet injection state.

• FwpsInjectionHandleDestroy0
  Destroys an injection handle that was previously created by calling the FwpsInjectionHandleCreate0 function.

• FwpsInjectNetworkReceiveAsync0
  Injects packet data into the receive data path.

• FwpsInjectNetworkSendAsync0
  Injects packet data into the send data path.

• FwpsInjectTransportReceiveAsync0
  Injects packet data from the transport, datagram data, or Internet Control Message Protocol (ICMP) error layers into the receive data path.

• FwpsInjectTransportSendAsync0
  Injects packet data from the transport, datagram data, or ICMP error layers into the send data path.

• FwpsPendOperation0
  Suspends packet processing, pending completion of another operation.

• FwpsQueryPacketInjectionState0
  Queries the injection state of packet data.

• FwpsReassembleForwardFragmentGroup0
  Assembles a list of IP fragments in the forwarding data path into a single packet.

• FwpsReferenceNetBufferList0
  Increments the reference count for a NET_BUFFER_LIST structure.

• FwpsStreamContinue0
  Resumes the processing of a previously deferred incoming data stream.

• FwpsStreamInjectAsync0
  Injects TCP data segments into a TCP data stream.

  Adds a callout to the filter engine.

• FwpmCalloutDeleteById0
  Deletes a callout from the filter engine.

• FwpmCalloutDeleteByKey0
  Deletes a callout from the filter engine.

• FwpmEngineClose0
  Closes a previously opened session to the filter engine.

• FwpmEngineOpen0
  Opens a session to the filter engine.
