[slang-users] push array structure into slang

[Joe Miller <lpe540@xxxxxxxxx>]

Hi, 

I was wondering how to push an array of slang structs
into slang from c.

I have a c function that returns an array of C
structures and I'd like to push onto slang. I've tried
to do this a bunch of different ways and have to find
a way that works. I was wondering if anyone had any
suggestions.

Here's one approach I took. I think it describes at
least what I'm trying to do.

typedef struct cstruct
{
   double       x;     // x position
   double       y;     // y position
} CSTRUCT, *CSTRUCT_P;

SLang_CStruct_Field_Type SLANG_XY [] =
{
   MAKE_CSTRUCT_FIELD(CSTRUCT, x, "x",
SLANG_DOUBLE_TYPE, 0),
   MAKE_CSTRUCT_FIELD(CSTRUCT, y, "y",
SLANG_DOUBLE_TYPE, 0),
   SLANG_END_CSTRUCT_TABLE
};

void sl_fucnc (void)
{
   CSTRUCT_P cp;
   int size = 4;
   c_func (cp, size);  //Where cfunc creates an array
of cp;
   SLang_Array_Type *at =
SLang_create_array(SLANG_STRUCT_TYPE,0,NULL,&size,1);
   SLang_Struct_Type *st;
   SLang_Any_Type *any;
   for (int ww = 0; ww < arg2; ww++){
   SLang_push_cstruct((VOID_STAR)&cp[ww], SLANG_XY);
   SLang_pop_anytype (&any);
   *((SLang_Struct_Type**)st) =
(SLang_Struct_Type*)any;
     SLang_set_array_element (at, &ww, st);
  }
  SLang_push_array(at,1);
  
}

Any thoughts or suggestion would be greatly
appreciated. I could be going about this all wrong so
let me know if you need more info.

Thanks.
