How to make a TCP Client/Server with C programming?

Question

Hello! I hope you are all doing well. I want to ask how to make a simple TCP or UDP client/server with W5500 EVB Pico. I can follow the examples for DHCP and SNTP, but I can't find any documentation for making a simple server/client with C Language. I don't really need the SSL example, just plain TCP/UDP data transaction. Is there any documentation I am missing for this module? I can't find anything except from whats in GitHub
