Hi Stephen,
As suggested by you, I tried following things for IPv4 only but still facing
the issue.
1) char address[INET_ADDRSTRLEN+1] = "10.65.156.197";
2) int socket_desc = socket (AF_INET, SOCK_STREAM, 0);
if (socket_desc == INVALID_SOCKET)
{
cout << "The error retuned by socket is" << errno << endl;
}
cout << "The socket is created successfully" << endl;
3) struct sockaddr_in addrinfo;
addrinfo.sin_family = AF_INET;
addrinfo.sin_port = htons(80);
inet_pton(AF_INET, address, &(addrinfo.sin_addr.s_addr));
int retval = connect(socket_desc, (struct sockaddr *)&addrinfo, sizeof
(addrinfo));
if (retval != 0)
{
cout << " The error returned by socket connect is" << errno << endl;
}
cout << "The socket is connected successfully" << endl;
4) BIO * conn;
conn = BIO_new_socket(socket_desc,0);
if(!conn)
{
cout << " The Bio_new_socket failed" << endl;
}
5) BIO_set_nbio(conn, 1);
6) int retVal = BIO_do_connect(conn);
if(retVal <= 0)
{
cout << " The Bio_do_connect failed" << endl;
}
After executing the program, I am getting output as :
The socket is created successfully
The socket is connected successfully
Bio_do_connect failed
Now I am not sure what I am missing here due to which it is getting failed
for IPv4 itself. Please suggest. Though I wanted to have API's support for
both IPv4 and IPv6 but situation seems to be complex here. I am not able to
execute SSL API's successfully for both IPv4 and IPv6. I am facing same
error in both the cases.
I would request to please have a look and suggest something.
Thanks
Akanksha Shukla.

What error are you getting? Have you tried exactly the same steps with an
IPv4
socket to see if it is a problem with you code and/or not specific to IPv6?
