Is this structure conversion correct?

[georgek01]

Hello!

Is this C++ structure converted correctly to MASM required structure?

Hello :)

Note that those members that are not DWORDs, are LP + something. In Microsoft's convention for naming the SDK data types, LP means it's a pointer - so they're really all DWORDs.

Hope that helps! :U

Except for ....

lpServiceClassId                GUID <?>

which should remain as written as it is a pointer to another structure.

Does the same then not apply to the following?

lpNSProviderId also points to a GUID

lpafpProtocols points to the following structure:

Code Select Expand


typedef struct _AFPROTOCOLS { 
    INT iAddressFamily; 
    INT iProtocol;
} AFPROTOCOLS,


lpVersion points to the following structure:

Code Select Expand


typedef struct _WSAVersion { 
    DWORD dwVersion; 
    WSAECOMPARATOR ecHow;
} WSAVERSION


lpcsaBuffer points to the following structure:

Code Select Expand


typedef struct _CSADDR_INFO {
    SOCKET_ADDRESS LocalAddr ;
    SOCKET_ADDRESS RemoteAddr ;
    INT iSocketType ;
    INT iProtocol ;
} CSADDR_INFO, *PCSADDR_INFO, FAR * LPCSADDR_INFO ;

You should define this as a DWORD, it is simply a pointer...

The LPGUID structure represents a long pointer to a GUID.

typedef struct _GUID {
  ULONG  Data1;
  USHORT  Data2;
  USHORT  Data3;
  UCHAR  Data4[8];
} GUID

typedef GUID *LPGUID;
