.Os
.Sh 名称
.Nm kvm_geterr
.Nd kvm 記述子でのエラー・メッセージを獲得する
.Sh 書式
.Fd #include <kvm.h>
.br
.Ft char *
.Fn kvm_geterr "kvm_t *kd"
.Sh 解説
この関数は
.Fa kd
記述子での最新のエラー状態を説明している文字列を戻します。
もしも最新の
.Xr kvm 3
ライブラリ呼び出しがエラーを引き起こさなかったならば、
その結果は定義されていません。戻された文字列は
.Xr kvm 3
が所有するメモリに保存されますので、
メッセージは必要があれば複写して別の場所に保存すべきです。
.Sh バグ
このルーチンは異常終了した
.Fn kvm_openfiles
呼び出しに基づくエラー条件のアクセスに使用できません。
異常終了は
.Dv ヌル
記述子を戻すことで指示されます。
このために、オープンに関するエラーは特別なエラー・バッファに出力され、
.Fn kvm_openfiles
に渡されます。このオプションは
.Fn kvm_open
には使用できません。
