macos - 处理锁定的文件

Question

我正在尝试识别锁定文本文件的进程。

我想用 Carbon 或 Cocoa 来做这个。

我是 MacAPI 新手，我来自 WinAPI。

谢谢

编辑:添加 corefoundation 标签，因为我听说 Carbon 已被弃用

您可以通过运行命令lsof来检查哪个进程正在使用文件，例如

lsof | grep file.txt

The  mode character is followed by one of these lock characters, describing the type of lock applied to the
              file:

                   N for a Solaris NFS lock of unknown type;
                   r for read lock on part of the file;
                   R for a read lock on the entire file;
                   w for a write lock on part of the file;
                   W for a write lock on the entire file;
                   u for a read and write lock of any length;
                   U for a lock of unknown type;
                   x for an SCO OpenServer Xenix lock on part      of the file;
                   X for an SCO OpenServer Xenix lock on the      entire file;
                   space if there is no lock.

              See the LOCKS section for more information on the lock information character.
