You Have A Problem With Your Winsock Code

In this guide, we’ll go over some of the possible causes that Winsock code can cause, and then suggest possible fixes that you can try to resolve the issue. Windows Socket API, also known as Winsock, is any type of application programming CP (API) used to communicate between Windows Link software and network services. It is based specifically on the Transmission Control Protocol / Internet Protocol (TCP / IP) and originates as the Berkeley Unix Sockets interface.

The main thing is the complete source code through the Winsock Basic TCP / IP client application.

What is the Winsock on a computer?

Winsock is probably the programming interface and program that handles I / O requests associated with Internet applications on the Windows system. It’s called Winsock because it’s actually a Windows adaptation of the Berkeley UNIX Sockets interface. There is a similar interface for Mac computers.
