IPsecSaEnum0 function

The IPsecSaEnum0 function returns the next page of results from the IPsec security association (SA) enumerator.

Note  IPsecSaEnum0 is the specific implementation of IPsecSaEnum used in Windows Vista. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information. For Windows 7 and later, IPsecSaEnum1 is available.
 

Syntax


DWORD WINAPI IPsecSaEnum0(
  _In_  HANDLE            engineHandle,
  _In_  HANDLE            enumHandle,
  _In_  UINT32            numEntriesRequested,
  _Out_ IPSEC_SA_DETAILS0 ***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 an IPsec SA enumeration. Call IPsecSaCreateEnumHandle0 to obtain an enumeration handle.

numEntriesRequested [in]

Type: UINT32

The number of enumeration entries requested.

entries [out]

Type: IPSEC_SA_DETAILS0***

Addresses of the enumeration entries.

numEntriesReturned [out]

Type: UINT32*

The number of enumeration entries returned.

Return value

Type: DWORD

Return code/valueDescription
ERROR_SUCCESS
0

The SAs were enumerated successfully.

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 using the same enumeration handle will return the next set of items following those in the last output buffer.

IPsecSaEnum0 works on a snapshot of the SAs taken at the time the enumeration handle was created.
