Thanks, Michael, I will check out SChannel.
int s;
int optval = 1;
s = socket (AF_INET, SOCK_STREAM, 0);
if (s < 0) {
perror("Unable to create socket");
exit(EXIT_FAILURE);
}
return s;
}
/* Create "bare" socket */
client_skt = create_socket;
Right now I'm attempting to compile sslecho using Microsoft Visual C++.
It's giving me an error which I can't figure out.
I'm guessing that this is because it's C++ instead of C.
int create_socket ()
{int s;
int optval = 1;
s = socket (AF_INET, SOCK_STREAM, 0);
if (s < 0) {
perror("Unable to create socket");
exit(EXIT_FAILURE);
}
return s;
}
int client_skt = -1;
client_skt = create_socket;

Robert's questions in his reply are pertinent – "communicates ... using Winsock" could mean a number of things.
But that aside: do you have a requirement to use OpenSSL? Windows includes its own TLS implementation, Microsoft's Schannel, and if you only need to support Windows that is, frankly, probably an easier route. OpenSSL has various advantages, such as portability and flexibility, but if all you need is normal TLS support for Windows only, Schannel will give you a somewhat simpler API (even simpler if you were using .NET) and integration with Windows PKI, which is often more convenient for Windows customers.
It would help to know more about what actual problem you're trying to solve, rather than what technology you think you should use to solve it.
