Since I got myself into this, here's a solution:
void manipulate_the_windows(Window *top)
{
Window *A = NULL, *B = NULL *C = NULL;
if (top != NULL) {
do_something_with_window(top);
A = get_subwindow(top);
}
if (A != NULL) {
do_something_different_with_window(A);
B = get_subwindow(A);
}
if (B != NULL) {
do_something_with_window(B);
C = get_subwindow(B);
}
if (C != NULL)
/* All windows I'm looking for are good, so do it */
do_something_weird_with_four_windows(top,A,B,C);
}
I'm not sure that this is exactly how I'd write this in a real-world
situation, but it does the job without multiple returns and without
deep nesting.
