[classic][Cata][4.4.0.55639] Enumerating Keybindings

[klumpen]

Hi!

I have a recurring issue where restarting my <program> fails to read player keybindings past the first 6 or so pointers.
Calling /reload in game and restarting the <program>, all keybindings get enumerated again.

Anyone else encountered such issues? Did you fix it by re-reading player keybindings off of some different address, or perhaps only reading them once on program startup?

Digging around a bit I found that there's two potentially applicable structs & loops. Added the second as a fallback, we'll see how that goes.

struct Keybind {
  next: Keybind, // 0x18
  bind: UTF8Pointer,  // 0x30
  action: UTF8Pointer, // 0x40
}
fn read_bindings () {
  let base = wow.base + keybindings.base; 
  let mut ptr = read_ptr(base + 0x50);
  while ptr != null {
    // ... 
    ptr = read_ptr(ptr.next);
  }
}

struct Keybind {
  next: Keybind, // 0x0, 
  bind: UTF8Pointer, // 0x20
  action: UTF8Pointer // 0x30
}
fn read_bindings_fallback() {
  let base = wow.base + keybindings.base; 
  let mut ptr = read_ptr(base + 0x48);
  while ptr != null {
    // ... 
    ptr = read_ptr(ptr.next);
  }
}

The pointer chain at keybinding.base + 0x48 appears to be the same list of keybindings but in reverse, at a glance.
