Example: Sort all items
public static int main (string[] args) {
PtrArray array = new PtrArray ();
array.add ("second entry");
array.add ("third entry");
array.add ("first entry");
array.sort ((a, b) => {
void** foo = a; void* _foo = *foo; // a is void*, but we get void**
void** bar = b; void* _bar = *bar; // b is void*, but we get void**
return strcmp ((string) _foo, (string) _bar);
});
// Output:
// ``first entry``
// ``second entry``
// ``third entry``
array.foreach ((ptr) => {
print ("%s\n", (string) ptr);
});
return 0;
}
