如果调用成功，返回下一个未使用的文件描述符；否则，返回 -1并相应地设置errno。
The stat() function fills a struct stat structure with information about a specific file; if you've got a file descriptor instead of a file name, you can use the fstat() function instead.
stat()函数会将特定文件的相关信息填入struct stat结构中，如果您获得的是文件描述符而不是文件名，那么作为替代，您可以使用fstat() 函数。
You later discovered that lsof shows the file descriptor of a process and the associated file name.
