How do I use use TCP on network with API?

Normally I have to use MSWINSOCK.OCX but that requires creating an installer for the program with the OCX file as a dependency. I want to make a portable program (no install required) that is capable of communication over a network via TCP.

For this I'll need an API function. But what function? If anyone can help out here, please do. Thanks in advance.

use the Winsock API. It has everything that the Winsock.ocx has plus more. I believe that the Winsock.OCX is just a wrapper for the Winsock API to simplify the Winsock API and has less features than usin the API.
