| Return code/value | Description |
|---|---|
|
The providers were enumerated successfully. |
|
A Windows Filtering Platform (WFP) specific error. See WFP Error Codes for details. |
|
Failure to communicate with the remote or local firewall engine. |
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.
FwpmProviderEnum0 works on a snapshot of the providers taken at the time the enumeration handle was created.
FwpmProviderEnum0 is a specific implementation of FwpmProviderEnum. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.
