The IPsecSaContextEnum0 function returns the next page of results from the IPsec security association (SA) context enumerator.

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

  _Out_ IPSEC_SA_CONTEXT0 ***entries,
  _Out_ UINT32            *numEntriesReturned
);
