The protocol to be used. The feasible options for the protocol parameter are distinct for the tackle relatives and socket form specified. Attainable values to the protocol are defined inside the Winsock2.h and Wsrm.h header data files.

The subsequent case in point displays how the Socket class can be utilized to deliver knowledge to an HTTP server, printing the ASCII reaction to your typical output. This example blocks the contacting thread till the whole page is gained.

The customer also really should detect itself into the server so it binds to an area port variety that it will use throughout this relationship. This is often assigned with the method.

Today, although the underlying protocols employed by the socket API have progressed through the years, and new kinds have designed, the reduced-amount API has remained the exact same.
