Once again look at the exit code, so we couldn't catch this kind of error or this kind of exception with this accept block.

再次查看退出代码，因此我们无法使用此 accept 块捕获此类错误或此类异常。

And a zero exit code is the same as you will get in a language like C, like 0 means everything went fine, there were no errors.

零退出代码与 C 等语言中的退出代码相同，0 表示一切顺利，没有错误。
