Hi Pierre,

The problem is that C or C++ are not good languges to do what you want to
do.  Pick a better language, like LISP or Perl.

Otherwise, package your parameter data better, such as:

typedef enum { kEndOfList, kString, kChar, kInt, kFloat, kDouble } Datum_t;
// Whatever you're interested in
struct Datum {
    Datum_t mType;
    void* mData;
};

void function_B(Datum* DataList)
{
    while(DataList->mType != kEndOfList)
    {
        switch(DataList->mType)
        {
            case kString: printf("--- %s\n", (char*)(DataList->mData));
break;
            case kChar: printf("--- %c\n", *(char*)(DataList->mData));
break;
            case kInt: printf("--- %d\n", *(int*)(DataList->mData)); break;
            case kFloat: printf("--- %f\n", *(float*)(DataList->mData));
break;
            case kDouble: printf("--- %lf\n", *(double*)(DataList->mData));
break;
            default: print("--- Danger, Will Robinson!\n");
        }
        ++DataList;
    }
}

I'll leave the packaging up of your data as an exercise.

Sincerely,
