The FD_SET macro adds a file descriptor to an fd_set. If the file descriptor already exist within the set, a duplicate will not be added.
A descriptor identifying a socket which will be added to the set.
A pointer to a fd_set.
Be careful not to confuse the FD_SET macro with the typedef of the fd_set structure that's also named FD_SET. That said, the FD_SET macro and the fd_set structure are related, and often used in conjunction.
