The size of the peer name is returned in bytes …
What is Sockaddr_storage?
The SOCKADDR_STORAGE structure stores socket address information. Since the SOCKADDR_STORAGE structure is sufficiently large to store address information for IPv4, IPv6, or other address families, its use promotes protocol-family and protocol-version independence and simplifies cross-platform development.
What is Winsock layer?
Winsock exists as a data link layer, and is also known as winsock. dll in our computers. It’s a dynamic library extension link. Winsock is pre-installed in every Microsoft Windows operating system, and is available for macOS too. The Windows Socket API includes two interfaces.
What is Af_inet?
AF_INET is an address family that is used to designate the type of addresses that your socket can communicate with (in this case, Internet Protocol v4 addresses). When you create a socket, you have to specify its address family, and then you can only use addresses of that type with the socket.
What is socket address?
