Support for Incomplete-Array in structs.

[mannprerak2]

C supports Flexible-Arrays as the last member of a struct having more than 1 member.
Structs of the following type -

struct T{
  int a;
  int b[]; // flexible array member, can only be at the end.
}

are not supported currently.

Could we support https://github.com/twain/twain-dsm/blob/master/TWAIN_DSM/src/twain.h#L218-L221

    typedef unsigned char TW_STR32[34],     FAR *pTW_STR32;
    typedef unsigned char TW_STR64[66],     FAR *pTW_STR64;
    typedef unsigned char TW_STR128[130],   FAR *pTW_STR128;
    typedef unsigned char TW_STR255[256],   FAR *pTW_STR255;

Which are used at https://github.com/twain/twain-dsm/blob/master/TWAIN_DSM/src/twain.h#L439

typedef struct {
   TW_UINT16  MajorNum;
   TW_UINT16  MinorNum;
   TW_UINT16  Language;
   TW_UINT16  Country;
   TW_STR32   Info;
} TW_VERSION, FAR * pTW_VERSION;

Hi @Sunbreak, add array-workaround: true in your config to generate this.

It result a quit long file with 16680 lines, T_T

I managed to hack like below:

// struct TW_VERSION {
//    TW_UINT16  MajorNum;
//    TW_UINT16  MinorNum;
//    TW_UINT16  Language;
//    TW_UINT16  Country;
//    TW_STR32   Info;
// };
class TWVersion extends _TWStruct<TW_VERSION> {
  static const _size = 2 + 2 + 2 + 2 + 34;

  TWVersion._fromAddress(int ptr): super._fromAddress(ptr);

  @override
  void dispose() {
    throw 'Undisposable nested structure';
  }

  @override
  int get size => _size;

  int get MajorNum => _getUint16(0);

  set MajorNum(int i) => _setUint16(0, i);

  int get MinorNum => _getUint16(2);

  set MinorNum(int i) => _setUint16(2, i);

  int get Language => _getUint16(4);

  set Language(int i) => _setUint16(4, i);

  int get Country => _getUint16(6);

  set Country(int i) => _setUint16(6, i);

  static const _InfoOffset = 2 + 2 + 2 + 2;

  String get Info => _getString(_InfoOffset, 34);

  set Info(String s) => _setString(_InfoOffset, s, 34);
}

It seems to work, even nested in another Struct _TWStruct<TW_IDENTITY>. But I'm not sure whether where is any problems

True, that's why we have chosen to keep it disabled by default. Hopefully, we should get inline array support soon.

I managed to hack...

That's a nice hack, but it cannot be used for all use cases (for example if these were pointers, the size would be 4/8 depending on the architecture).
Edit: Also you can't pass this by value.

Any plan?
