英文:
Tell whether net.Listener is dead
问题
在Go语言中，调用net.Listener类型的Accept方法会返回一个错误。然而，有没有办法区分临时错误（例如，连接设置失败）和永久错误（例如，监听器已经关闭，比如强制删除的Unix域套接字文件）？如果我无法区分这两种错误，就有可能陷入无限循环，并且每次调用Accept都会立即返回一个错误，导致错误不断输出。
英文:
In Go, a call to the net.Listener type's Accept method returns an error. However, is there a way to tell the difference between a transient error (ie, this connection failed to set up) vs a permanent error (ie, the listener is dead, such as a Unix domain socket file that was forcibly removed)? If I can't tell the difference, I run the risk of infinite looping and spitting out errors as fast as I can since each Accept call will immediately return an error.

得分: 2
我明白了。net 包返回的错误可能是 net.Error 类型，该类型定义了 Temporary() bool 方法，用于判断错误是否是临时的。
英文:
Figured it out. Errors returned by the net package may be of the net.Error type, which defines the Temporary() bool method which reports whether the error is temporary.
