●PTRACE_ATTACH
pid で指定されたプロセスに接続 (attach) し、それを現在のプロセスの子プ
ロセスとしてトレースできるようにする。子プロセスは PTRACE_TRACEME した
かのように振舞う。現在のプロセスはそのほとんどの目的において、 その子プ
ロセスの実際の親になる (例えば、子プロセスのイベントの 通知を受けとった
り、 ps(1) で親として表示されたりする)。しかし、子プロセスで
getppid(2) を実行した場合には元の親プロセスの PID が返される。 子プロセ
スには SIGSTOP が送られるが、この呼び出しが完了するまでに 必ずしも停止
するとは限らない。子プロセスの停止を待つには wait(2) を使用すること。
