Check the comments in the file <safearry.h> for help on using SAFEARRAY
wrappers...

#include <safearry.h>

void __fastcall CallGetSymbols()
{
  int nDim1 = 1; //Number of items for Symbols
  int nDim2 = 1; //Number of items for WordenNumbers

//Note- I used 1 for the number of elements because that is
//what it look slike AllocateArray is doing...
//Also note that TSafeArrayDim1 sets the lower bound to 0 while your
AllocateArray is setting to 1...

  TSafeArrayDim1  SymbolsDim(nDim1);
  TSafeArrayDim1  WordenNumbersDim(nDim2);

  TSafeArrayBSTR1 Symbols(SymbolsDim);
  TSafeArrayLong1 WordenNumbers(WordenNumbersDim);

//If arrays need to be prefilled, use the following.
//If you are just passing empty arrays into GetSymbols and letting
GetSymbols fill in the arrays,
//the skip...

  for(int i=0; i<nDim1; i++)
  {
    AnsiString cVal;
//set cVal to whatever...
    Symbols[i] = WideString(cVal).Detach();
  }

  for(int i=0; i<nDim2; i++)
  {
    int nVal;
//set nVal to whatever...
    WordenNumbers[i] = nVal;
  }


  GetSymbols( &Symbols,  &WordenNumbers);
}
