    You seem to mis-understand what denial of service means. An example would be a large number of HTTP requests to a single web-server arriving at such a rate that the web-server software becomes so busy it cannot accept new TCP connections. Wikipedia has a decent article on DoS, read it.

    recv(2) is just an API. Misuse of it, as any other bug, can lead to issues, including DoS. But that does not mean you should avoid it. If your problem is blocking other sockets while waiting on a read, look into non-blocking sockets and I/O multiplexing as in select(2), poll(2), and epoll(4).
