select（）的最大插座 [英] select() max sockets
问题描述
只是更异步的东西！
好吧，所以我现在有一个工作的异步接口方案，我主要的聊天应用，它的工作真的很好！但是我有一个担心。
Alright, so I now have a working asynchronous socket program for my main chatting application, and it's working really well! However I have one concern..
虽然使用select（）什么是我可以在每一组使用的文件描述符的最大数量？我读过有关1024的极限......
While using select() what is the maximum number of file descriptors that I can use in each set? I've read about a limit of 1024...
如果该限制，的确难以codeD，一旦我达到这个限制，我不能FD_SETSIZE任何更高，我应该产卵另一个线程的限制？或者是其他东西？这是甚至担心？
If that limit is indeed hard coded and I can't FD_SETSIZE the limit any higher, should I spawn another thread once I reach that limit? Or something else? Is this even a concern?
推荐答案
是的，FD_SETSIZE有1024的限制，您可以方便地查看通过查看select.h头。人们试图增大限制，但是从报告的工作到崩溃了一段时间后会有所不同。如果你需要很多的连接，使用调查代替。
Yes, the FD_SETSIZE has a limit of 1024. You can easily check that by looking at the select.h header. People have tried to increase the limit, but the reports vary from "working" to "crashing" after a while. If you need that many connections, use poll instead.
