IPsecSaEnum1 function (fwpmk.h)

The IPsecSaEnum1 function returns the next page of results from the IPsec security association (SA) enumerator.

Syntax

NTSTATUS IPsecSaEnum1(
  [in]  HANDLE            engineHandle,
  [in]  HANDLE            enumHandle,
  [in]  UINT32            numEntriesRequested,
  [out] IPSEC_SA_DETAILS1 ***entries,
  [out] UINT32            *numEntriesReturned
);

Parameters

[in] engineHandle

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

[in] enumHandle

Handle for an IPsec SA enumeration. Call IPsecSaCreateEnumHandle0 to obtain an enumeration handle.

[in] numEntriesRequested

The number of enumeration entries requested.

[out] entries

Addresses of the enumeration entries.

[out] numEntriesReturned

The number of enumeration entries returned.

Return value

Return code/value Description
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.
Other NTSTATUS codes An error occurred.

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.

IPsecSaEnum1 works on a snapshot of the SAs taken at the time the enumeration handle was created.

IPsecSaEnum1 is a specific implementation of IPsecSaEnum. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.
