Has anyone any example clue about using the FirstThat function with a list container such as TSListImp on Borland C++.

If memory serves:


int CondFunction (const obj &o, void *p) {
  o.testIt (p);
  }

int obj::testIt (void *p) {
  return *(int *)p == 5; // or whatever
  }

TSListImp <obj> list;
...
int testval = 4;
const obj &TheFirstItem = list.FirstThat (CondFunction, &testval);

Would just need an opinion on the global program construction.
Maybe, most of the time, the function 'CondFunction' is very specific to the function from which it is called.
Haven't seen yet a better way to arrange the program.

Commented:
Yes, that's the intent.  It allows the object to do it's own testing.
