Pointer to an CallBack

Is it posible to make a sort function with an pointer to an callback?

PHP Code:

---

//...
void Sort(LPCSTR *CallBackName) // This can't compile....!!
{
        qsort(this->GetData(), this->GetSize(), sizeof(ARG_T), CallBackName);
//... 


---

The prototype for qsort is

Code:

---

void qsort(
  void *base,
  size_t num,
  size_t width,
  int (__cdecl *compare )(const void *, const void *)
);

---

So the function you want must have the same prototype as the compare function:

Code:

---

int compare( const void *arg1, const void *arg2 )
{
    ARG_T *argT_1 = (ARG_T *)arg1;
    ARG_T *argT_2 = (ARG_T *)arg2;

    if (argT_1 > argT_2 ) return 1;
    else if (argT_1 < argT_2) return -1;
    else return 0;
}

---

void Sort(int (__cdecl *CallBackName)(const void *, const void *) ) {

qsort(this->GetData(), this->GetSize(), sizeof(ARG_T), CallBackName);

}

Thanks!!!
