对我而言似乎并没有找到支持我意见的链接。你怎么看？

It seems not to me and I found a link that supports my opinion. What do you think?

推荐答案

你发布的链接内容是正确的。在非阻塞模式下打开的常规文件套接字将始终准备好进行读取;当你真正尝试阅读它时，阻塞（或更准确地说，你的来源指出，睡觉）将会发生，直到操作成功。

The content of the link you posted is correct. A regular file socket, opened in non-blocking mode, will always be "ready" for reading; when you actually try to read it, blocking (or more accurately as your source points out, sleeping) will occur until the operation can succeed.

无论如何，我认为你的来源需要一些镇静剂。一个愤怒的人，就是这样。

In any case, I think your source needs some sedatives. One angry person, that is.
