问题是我想生成一些原始数据"流，即我的意思是一个随机的1和0的流，接下来，我想通过udp套接字发送此生成的流.

关于如何生成该流的任何想法?

我希望我的问题很清楚，并在此先感谢

Hi everyone,

Tools:

* OS: Win XP,
* MSVC++

The problem is that I want to generate some "raw data" flow, by that I mean a flow of random 1s and 0s, next I want to send this generated flow over udp sockets.

any ideas on how to generate that stream?

I hope I was clear in my question and thanks in advance

推荐答案

您需要使用位计数字段和包含位的字节数组来创建消息，因为您不能只发送一个位，然后再在UDP数据包中发送所有这些位.如果您只发送8位的倍数，则即使需要发送计数字段也不需要发送计数字段.

You need to create your message using a bit count field and a byte array containing the bits, since you cannot send just a single bit, and then send all this in your UDP packet. If you only send a multiple of 8 bits, you don''t need to send the count field, even though it would probably be a good idea.

在VC2010中，使用 std :: uniform_int [

Hi,

With VC2010 use std::uniform_int[^] or another random generator in <random>.
With VC2008 use the same in std::tr1 namespace.
With prior compilers use int rand(); in <cstdlib>.

cheers,
