FwpmNetEventEnum0 function

The FwpmNetEventEnum0 function returns the next page of results from the network event enumerator.

Note  FwpmNetEventEnum0 is the specific implementation of FwpmNetEventEnum used in Windows Vista. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information. For Windows 7, FwpmNetEventEnum1 is available. For Windows 8, FwpmNetEventEnum2 is available.

Syntax


DWORD WINAPI FwpmNetEventEnum0(
  _In_  HANDLE          engineHandle,
  _In_  HANDLE          enumHandle,
  _In_  UINT32          numEntriesRequested,
  _Out_ FWPM_NET_EVENT0 ***entries,
  _Out_ UINT32          *numEntriesReturned
);

Parameters

engineHandle [in]

Type: HANDLE

Handle for an open session to the filter engine. Call FwpmEngineOpen0 to open a session to the filter engine.

enumHandle [in]

Type: HANDLE

Handle for a network event enumeration created by a call to FwpmNetEventCreateEnumHandle0.

numEntriesRequested [in]

Type: UINT32

The number of enumeration entries requested.

entries [out]

Type: FWPM_NET_EVENT0***

Addresses of enumeration entries.

numEntriesReturned [out]

Type: UINT32*

The number of enumeration entries returned.

Return value

Type: DWORD

Return code/valueDescription
ERROR_SUCCESS
0

The network events were enumerated successfully.

FWP_E_NET_EVENTS_DISABLED
0x80320013

The collection of network diagnostic events is disabled. Call FwpmEngineSetOption0 to enable it.

FWP_E_* error code
0x80320001—0x80320039

A Windows Filtering Platform (WFP) specific error. See WFP Error Codes for details.

RPC_* error code
0x80010001—0x80010122

Failure to communicate with the remote or local firewall engine.

 

Remarks

If the numEntriesReturned is less than the numEntriesRequested, the enumeration is exhausted.

The returned array of entries (but not the individual entries themselves) must be freed by a call to FwpmFreeMemory0.

A subsequent call that uses the same enumHandle parameter will return the next set of events following those in the current entries buffer.

FwpmNetEventEnum0 returns only events that were logged prior to the creation of the enumHandle parameter. See Logging for more information.
