からの関数のいくつかを使用して、IOKit/kext/KextManager.hカーネルに拡張機能をプログラムでロードしていますが、新しいエラー値が発生しています。例えば：

OSReturn osr = KextManagerLoadKextWithIdentifier(...);
// => -603947004

この値を、にある人間が読める形式の定義の1つに変換するにはどうすればよいlibkern/OSReturn.hですか？

@pmjordanのコメントによると、からの定義を使用して単純なマッピング関数を作成しましたOSReturn.h。

- (void)human_readable_libkern_metaclass_error_message:(int) n {
  switch(n){
    case 0:
      printf("%s", "no error");
      break;

XXXの読み込みに失敗しました-（libkern / kext）特権がありません。システム/カーネルログでエラーを確認するか、kextutil（8）を試してください。

ルート権限なしでkextloadを試行したときに表示されるエラーメッセージ。

-603947004 - this code appears in OSReturn when you try to load the kext via code without root privileges. The above code for translation works well for defined cases but for undefined error codes invoking the command via terminal helps.
