Description

The enumerator was created successfully

FWP_E_* error code

0x80320001-0x80320039

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

RPC_* error code

0x80010001-0x80010122

Failure to communicate with the remote or local firewall engine

Remarks

If enumTemplate is NULL, all filters are returned.

The enumerator is not "live", meaning it does not reflect changes made to the system after the call to FwpmFilterCreateEnumHandle0 returns. If you need to ensure that the results are current, you must call FwpmFilterCreateEnumHandle0 and FwpmFilterEnum0 from within the same explicit transaction.

The caller must free the returned handle by a call to FwpmFilterDestroyEnumHandle0.

The caller needs FWPM_ACTRL_ENUM access to the filters' containers and FWPM_ACTRL_READ access to the filters. Only filters to which the caller has FWPM_ACTRL_READ access will be returned. See WFP Access Right Identifiers for more information.
