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

I'm just being curious, but is this some experiment your doing or is it part of an use case of a real application?

It becomes the same if we intend to solve the problem...why? is this similar to a project you're working on?

Solution 1

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.

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,
AR
