实际上,紧急数据跟带外数据不是一回事,tcp并没有另外建立一条逻辑连接传输数据,只是socket api 中把紧急数据叫做带外数据而已。 The confusion between TCP's urgent mode and out-of-band data is also because the predominant programming interface, the sockets API, maps TCP's urgent mode into what socket...
TCP的紧急方式是发送端向另一端发送紧急数据的一种方式。实际上,紧急数据跟带外数据不是一回事,tcp并没有另外建立一条逻辑连接传输数据,只是socket api 中把紧急数据叫做带外数据而已。 The confusion between TCP'surgent modeandout-of-banddata is also because the predominantprogramming interface, the sockets ...
-a: all,显示所有的 socket,默认只显示非 listening 状态的 -t: tcp,显示 tcp socket -u: udp,显示 udp socket -w: raw,显示 raw sockt -x: unix,显示 unix domain socket。可以看到 virtual box 使用了 domain socket。 -p: processes,显示开启此 socket 的进程,不过很多时候无法显示,不知道为什么 -n...

Introduction: Beginning in Insider Build 17063, you’ll be able to use the unix socket (AF_UNIX) address family on Windows to communicate between Win32 processes. Unix sockets allow inter-process communication (IPC) between processes on the same machine. Overview: Support for the unix socket ha...
