Thomas,

is this functionality implemented? I think it might be difficult and might
therefore not be implemented...

Best regards

Hi,

I tried to use the function setSoReuseAddress() function present in cppsocketapi directory but the result is "SCTP bind error: Address already in use". I also tried to set the option SO_REUSEADDR through socketapi (C functions) using function ext_setsockopt, but there too it is giving me the same result.

Am i using the function in a wrong way. If so please tell me the correct way to resue this Socket option.

Below is the sample program

#include <cstdio>
#include <iostream.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/uio.h>
#include "tdsystem.h"
#include "thread.h"
#include "tdsocket.h"
#include "tdmessage.h"
#include "randomizer.h"
#include "breakdetector.h"
#include "ext_socket.h"
#include <signal.h>
int main(int argc,char *argv[])
{
struct sockaddr_in servaddr;
bool boolres=false;

cout<<"Initially boolres variable is: "<<boolres;
// SCTP handling starts
Socket clientSocket1(Socket::IP,Socket::Stream,Socket::SCTP);
cout<<"\nSocket Initialized successfully--1";
boolres = clientSocket1.setSoReuseAddress(true);
printf("\nThe result of setsoreuse-1 is %d",boolres);

//Binding the SCTP socket
bzero(&servaddr, sizeof(servaddr));
servaddr.sin_family = AF_INET;
servaddr.sin_port = htons(atoi(argv[1]));
servaddr.sin_addr.s_addr = htonl(INADDR_ANY);

InternetAddress address1((struct sockaddr *)&servaddr,sizeof (servaddr));
if (clientSocket1.bind(address1)== false)
{
perror("\nSCTP bind error");
exit(1);
}
printf("\nSocket bounded successfully--1");
Socket clientSocket2(Socket::IP,Socket::Stream,Socket::SCTP);
cout<<"\nSocket Initialized successfully--2";
if (clientSocket2.bind(address1) == false)
{
perror("\nSCTP bind error");
exit(1);
}
printf("\n Socket bounded successfully--2");
printf("\n Socket bounded successfully--2");
}

I will be thankful for your response.

Thanks and regards
Rohit Agrawal
