Description |
|---|---|
ERROR_SUCCESS 0 |
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 |

Remarks
If enumTemplate is NULL, all providers are returned.
The enumerator is not live, meaning it does not reflect changes made to the system after the call to FwpmProviderCreateEnumHandle0 returns. If you need to ensure that the results are current, you must call FwpmProviderCreateEnumHandle0 and FwpmProviderEnum0 from within the same explicit transaction.
The caller must free the returned handle by a call to FwpmProviderDestroyEnumHandle0.
The caller needs FWPM_ACTRL_ENUM access to the providers' containers and FWPM_ACTRL_READ access to the providers. Only providers to which the caller has FWPM_ACTRL_READ access will be returned. See WFP Access Right Identifiers for more information.
