Driver Management Functions (Compact 7)

3/12/2014

The semantics of the WFP callout driver management functions are the same whether called from a callout driver or a user-mode application, except that the return type is an NTSTATUS code instead of a Win32 error code. For a description of each of these functions, see Functions Called by Callout Drivers.

Callers of these functions must be running at IRQL = PASSIVE_LEVEL, except for FwpmFreeMemory0. Callers of FwpmFreeMemory0 must be running at IRQL <= DISPATCH_LEVEL.

The WFP callout driver management functions are described as follows:

• FwpmCalloutAdd0
  Adds a new callout object to the system

• FwpmCalloutDeleteByKey0
  Removes a callout object from the system

• FwpmCalloutGetByKey0
  Retrieves a callout object

• FwpmEngineClose0
  Closes a session to the WFP Filter Engine

• FwpmEngineOpen0
  Opens a session to the filter engine

• FwpmFilterAdd0
  Adds a new filter object to the system

• FwpmFilterCreateEnumHandle0
  Creates a handle that is used to enumerate a set of filter objects

• FwpmFilterDeleteById0

• FwpmFilterDeleteByKey0

• FwpmFilterDestroyEnumHandle0
  Frees a handle returned by FwpmFilterCreateEnumHandle0

• FwpmFilterEnum0
  Returns the next page of results from the filter enumerator

• FwpmFilterGetById0
  Retrieves a filter object

• FwpmFilterGetByKey0
  Retrieves a filter object

• FwpmProviderAdd0
  Adds a new provider to the system

• FwpmProviderContextAdd0

• FwpmSubLayerAdd0
  Adds a new sub-layer to the system

• FwpmSubLayerDeleteByKey0
