Sample text

Set up the array of file descriptors. // // in this example, we want to know when there’s normal or out-of-band // data ready to be recv()’d... 5 second timeout rv = poll(ufds, 2, 3500); if (rv == -1) { perror("poll"); // error occurred in poll() } else if (rv == 0) { printf("Timeout occurred! 15. h> ssize_t recv(int s, void *buf, size_t len, int flags); ssize_t recvfrom(int s, void *buf, size_t len, int flags, struct sockaddr *from, socklen_t *fromlen); Description Once you have a socket up and connected, you can read incoming data from the remote side using the recv() (for TCP SOCK_STREAM sockets) and recvfrom() (for UDP SOCK_DGRAM sockets).

What to do? If they’re anywhere, they’ll be in POSIX libraries that may have shipped with your compiler. Since I don’t have a Windows box, I really can’t tell you the answer, but I seem to remember that Microsoft has a POSIX compatibility layer and that’s where fork() would be. ) Search the help that came with VC++ for “fork” or “POSIX” and see if it gives you any clues. If that doesn’t work at all, ditch the fork()/sigaction stuff and replace it with the Win32 equivalent: CreateProcess(). I don’t know how to use CreateProcess()–it takes a bazillion arguments, but it should be covered in the docs that came with VC++.

In short, no changes are necessary to any of the code to make it run on a single non-networked machine! Huzzah! How can I tell if the remote side has closed connection? You can tell because recv() will return 0. How do I implement a “ping” utility? What is ICMP? Where can I find out more about raw sockets and SOCK_RAW? All your raw sockets questions will be answered in W. Richard Stevens’ UNIX Network Programming books. See the books section of this guide. How do I build for Windows? First, delete Windows and install Linux or BSD.
