The protocol to be used. The attainable choices for the protocol parameter are certain on the tackle household and socket variety specified. Doable values for that protocol are outlined while in the Winsock2.h and Wsrm.h header files.

The socket address is a mix of IP tackle and port. During the TCP/IP layer, a socket is certain being a port number which might establish whether or not the details is to be despatched to an software or not.
