IPsecSaContextEnum1 function (fwpmu.h)

  • Article

The IPsecSaContextEnum1 function returns the next page of results from the IPsec security association (SA) context enumerator.

Note  IPsecSaContextEnum1 is the specific implementation of IPsecSaContextEnum used in Windows 7 and later. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information. For Windows Vista, IPsecSaContextEnum0 is available.
 

Syntax

DWORD IPsecSaContextEnum1(
  [in]  HANDLE            engineHandle,
  [in]  HANDLE            enumHandle,
  [in]  UINT32            numEntriesRequested,
  [out] IPSEC_SA_CONTEXT1 ***entries,
  [out] UINT32            *numEntriesReturned
);

Parameters

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

Type: UINT32

Number of SA contexts requested.

[out] entries
