Running this program, you can receive messages using Redis’ pub/sub capabilities. 

I couldn’t believe how easy this was.

#include <hiredis/hiredis.h>
#include <string>
#include <iostream>


int main()
{
    void* reply_alloc;
    /* You can change this to listen to a remote channel port if the server is
     * configured to accept connections on that port.
     */
    redisContext* redis= redisConnect("localhost",6379); 

    /* You can subscribe to any number of channels with 
     * this command, and all messages 
     * published by this channel will appear in your CLI.
     */
    reply_alloc = (void*)redisCommand(redis,"subscribe foo"); 

    while (redisGetReply(redis,&reply_alloc)==REDIS_OK)
    {   
        redisReply* reply = (redisReply*)reply_alloc;
        if (reply->type == REDIS_REPLY_ARRAY)
        {   
            std::string message = reply->element[2]->str;
            std::cout << message << std::endl;
        }   
    }   
}

So easy! I love Redis so much!
