Hi!
Perhaps somebody can help me...

I'm trying to create COM interface and struct declarations in C# to access
parts of SAPI 4.0a.

The problem is that several structs look similar to this:
typedef struct {  // srw
    DWORD  dwSize;
    DWORD  dwWordNum;
    WCHAR  szWord[ ];
} SRWORD, *PSRWORD;
where I don't know how to tell .NET how to marshal the WCHAR[].
In the case above, dwSize holds the size of the struct plus the size of
szWord rounded up to the nearest multiple of four (as specified by the docs).
Another struct is declared as
typedef struct {  // srp
    DWORD  dwSize;
    BYTE   abWords[0];
} SRPHRASE, *PSRPHRASE;

I guess using MarshalAs(UnmanagedType.LPArray, ConstSize=0 is not _really_
something that will work...

Is there a way to marshal these structs?

And when a function requires such a struct as an argument (in/out), how do I
call this function?

Any help would be greatly appreciated...
