3.14.4.1 InitializeAdapterConfiguration (Opnum 3)

  • Article

The InitializeAdapterConfiguration method initializes the server Firewall State to process subsequent calls of GetNextAdapterFirewallConfiguration.

This method is called at least once before GetNextAdapterFirewallConfiguration.

 HRESULT InitializeAdapterConfiguration(
   [out] unsigned long* cRetAdapters
 );

cRetAdapters: A pointer to an unsigned 32-bit integer indicating the number of adapters in the network adapter index of the Firewall State. Upon successful completion of this method, the server MUST set this value. If the method fails, the client MUST ignore this value.

Return Values: A signed 32-bit value that indicates return status. If the method returns a negative value, it has failed. Zero or positive values indicate success, with the lower 16 bits in positive nonzero values containing warnings or flags defined in the method implementation. For more information about Win32 error codes and HRESULT values, see [MS-ERREF] sections 2.2 and 2.1.
