C++ (Cpp) NewSList Examples

Example #1

File: lists.c Project: swift2plunder/DoW

int main(int argc, char** argv) {
  SList* sl;
  int val;

  sl = NewSList(10);
  for (;;) {
    if (scanf("%d", &val) != 1) {
      break;
    }
    AddToSList((void*) val, val, sl);
  }
  ApplySList(sl, printval, 0);
  printf("\n\nDebug out:\n\n");
  print_slist(sl);
