c ++发布中使用的udp端口

Question

I am currently working on an add-on for a dedicated server of halo, however the server tends to crash every now and then and the port stays in use.

So when the program is restarted after a crash it doesn't transmit any information internally (localhost) or over the internet.

What we could do is add a function to our addon that automatically Releases/makes the port available at the start of the program and then let the program initialize it self again so it works fine.

However we have no knowledge about udp or network programming in c++ at this moment, so we are basically asking if someone knows if this is possible(or some other way of fixing this problem) and how to make this in c++ for windows.

We already googled some but couldn't find anything useful.

Answer 1

程序应使用套接字选项SO_REUSEADDR，这将允许在程序重新启动后使用套接字。
