10022 is defined as &quot;WSAEINVAL&quot;, which usually means &quot;An invalid argument was supplied.&quot;, but if you read the documentation for bind(), it says that it will return that value when &quot;The socket is already bound to an address.&quot;<br />
<br />
Is there more to your code than just that?<br />
<br />
I think the problem may be in the first line, because I reviewed my socket library, and it seems to do what you're doing. &nbsp;The main difference is that I am SOCK_STREAM instead of SOCK_RAW, 0 for the protocol type. &nbsp;So try changing it to this line:<br />
&nbsp; &nbsp; &nbsp;s=WSASocket(AF_INET, SOCK_STREAM, 0, NULL, 0,0);<br />
<br />
Hope that Helps,<br />

Than it will be regular TCP connection...<br />
What I want to do is to receive and handle all packets like SYN, ACK, RST.<br />
It looks like I need to use RAW socket for this task.

If I don't bind() socket how can I receive packets? On which port ?
