how to run the 'multi' command?

[LazyHippogriff]

I want to implement atomic execution of a bunch of statements for which I need to execute the 'multi' command. However, I'm getting error. Given below is my program:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include<unistd.h>
#include <hircluster.h>
#include<iostream>
#include<string>
#include<vector>
using namespace std;

int main(int argc, char **argv) {
struct timeval timeout = { 1, 500000 }; // 1.5 seconds
redisClusterContext *cc = redisClusterContextInit();
redisClusterSetOptionAddNodes(cc, "172.16.129.68:6380");
redisClusterSetOptionConnectTimeout(cc, timeout);
redisClusterSetOptionRouteUseSlots(cc);
redisClusterSetOptionParseSlaves(cc);

redisClusterConnect2(cc);
if (cc != NULL && cc->err) {
  printf("Error: %s\n", cc->errstr);
  // handle error
  exit(-1);
}

redisReply *reply;
reply = (redisReply*)(redisClusterCommand(cc,"MULTI"));
if (cc != NULL && cc->err)
printf("\n[%s::%d]Error: %s\n",__FILE__,__LINE__,cc->errstr);
else
printf("MULTI RESPONSE: %s\n", reply->str);
freeReplyObject(reply);
redisClusterFree(cc);
return 0;
}

Output

[cluster-example.c::52]Error: Parse command error. Cmd type: 0, state: 5, break position: 13.
