1. structure for GetAdaptersAddresses

Hi All,
I'm struggling with defining a structure (using win32lib) for
  GetAdaptersAddresses.. I need this to get the 'friendly name' for Network
  adapters. The structure is

typedef struct _IP_ADAPTER_ADDRESSES {
   union {                                              
       ULONGLONG Alignment;                             
       struct {                                         
           ULONG Length;                                
           DWORD IfIndex;                               
       };                                               
   };                                                   
   struct _IP_ADAPTER_ADDRESSES *Next;                  
   PCHAR AdapterName;                                   
   PIP_ADAPTER_UNICAST_ADDRESS FirstUnicastAddress;     
   PIP_ADAPTER_ANYCAST_ADDRESS FirstAnycastAddress;     
   PIP_ADAPTER_MULTICAST_ADDRESS FirstMulticastAddress; 
   PIP_ADAPTER_DNS_SERVER_ADDRESS FirstDnsServerAddress;
   PWCHAR DnsSuffix;                                    
   PWCHAR Description;                                  
   PWCHAR FriendlyName;                                 
   BYTE PhysicalAddress[MAX_ADAPTER_ADDRESS_LENGTH];    
   DWORD PhysicalAddressLength;                         
   DWORD Flags;                                         
   DWORD Mtu;                                           
   DWORD IfType;                                        
   IF_OPER_STATUS OperStatus;                           
   DWORD Ipv6IfIndex;                                   
   DWORD ZoneIndices[16];                               
   PIP_ADAPTER_PREFIX FirstPrefix;                      
} IP_ADAPTER_ADDRESSES, *PIP_ADAPTER_ADDRESSES;   

So far I have...

constant
  MAX_ADAPTER_ADDRESS_LENGTH     = 8 ,
  char_    = #01000001,
-- typedef struct _IP_ADAPTER_ADDRESSES {  
-- 	union {    ULONGLONG Alignment;  		  
-- 	struct {      
-- 		ULONG Length;     					 
-- 		DWORD IfIndex;    };  };  				
  IP_ADAPTER_ADDRESSES_Next	= w32allot(Ptr),  
  AdapterName			= w32allot(char), 
  PIP_ADAPTER_UNICAST_ADDRESS 	= w32allot(Ptr), 
  PIP_ADAPTER_ANYCAST_ADDRESS 	= w32allot(Ptr),
  PIP_ADAPTER_MULTICAST_ADDRESS = w32allot(Ptr), 
  PIP_ADAPTER_DNS_SERVER_ADDRESS= w32allot(Ptr), 
  DnsSuffix		        = w32allot(char_*2),
  IP_Description	        = w32allot(char_*2),  
  FriendlyName		        = w32allot(char_*2), "
  PhysicalAddress	= w32allot({MAX_ADAPTER_ADDRESS_LENGTH, Byte}),  
  PhysicalAddressLength	       = w32allot(DWord),	
  Flags			       = w32allot(DWord),  
  Mtu			       = w32allot(DWord), 
  IfType		       = w32allot(DWord),	
-- 		IF_OPER_STATUS OperStatus;  
  Ipv6IfIndex		       = w32allot(DWord),  
  ZoneIndices		       = w32allot(16, DWord),  
  PIP_ADAPTER_PREFIX 	       = w32allot(Ptr)

Assuming (*big* assumption, probably wrong!) that the ones already defined are
  correct, the commented ones are my problems...

 Help anyone? please!

Thanks Brian, I had seen your Macaddy and that is almost there but I want to get
the 'Friendly name' - that is the name of the adapter that is shown in the
Network Connections folder and the only way I can see is with the
'GetAdaptersAddresses' which you don't currently have wrapped.

This is for an old program I am rewriting, it is for changing the Ethernet
   address, currently it runs the ipconfig command into a file then reads that for
   the friendly names, I then use these friendly names to build a file as input to a
   netsh command. The running of the ipconfig causes a dos screen to flash up and I
   want to get rid of that, also tieing together the friendly name with the
   'Windows' adapter name may give me another way to change the IP address...

Any help is appreciated...

Its unclear if the name from GetInterfaceInfo is the friendly name or not, but
it doesn't seem to be. I need the friendly name so it is clear which adapter the
program is using (and also for the netsh command), but then I need to tie the
friendly name to whatever else I need to display the IP address in use by that
adapter..

All,
FYI, I got the structure wrapped in the end, and am now getting the list of
adapter info I needed, I'll add it to the archive (after a bit of tidying up!).

Brian, I needed to get the IP address for each adapter, which is returned with
the GetAdaptersInfo call but was missing from your Macaddy wrapper. I've added
that in and sent you a revised file along with an extended demo..
