Sending commands to a socket (C++)

Posted by LindonNetworks, 09-19-2008, 05:53 PM

I'm trying to write an SMTP wrapper and I'm connecting to the mail server with winsock and connect successfully but how do I send the commands? send(lhSocket,"HELO\\r",strlen("HELO\\r"),0); Does it need to be \n to end the command?

You're escaping the return with \\r, return (\r) and newline (\n) are a bit different you might want to use both like this Also note that strlen() returns when it hits a NULL character, it might be a better idea to use sizeof() in this case. Last edited by DigitalLinx; 09-20-2008 at 08:26 AM.
