Is there an ipc option to get the last message in message queue but not removing it?
I want this to allow many clients reading same messages from the same server..
Thanks

I'm trying to stop a TCP Listener as my program is exiting. I do not care about any data that is currently active on the socket or any of the active client sockets.
The socket clean up code is essentially:

My initial UDP socket is binded to 127.0.0.1:9898.
The first time that I get notified of incoming data by epoll/kqueue, I do recvfrom() and I fill a struct sockaddr called peer_name that contain the peer informations (ip:port).
Then I create a new UPD socket using socket(),
then I bind() this newly created socket to the same ip:port…
I have created a socket using the following lines of code.
Now i change the value of the socket i get like this

Even now the send recv socket functions succeeds without throwing SOCKET_ERROR.
I expect that it must throw error.

Hi all,
I am implementing a simulated b/s stock data system. I am using flex and c# for client and server sides. I found flash has a security policy and I handled the policy-file-request in my server code. But seems it doesn't work, because the code jumped out at "socket.Receive(b)" after connection. I've tried sending message on…
How would you test a developer that claims to have *nix shell experience (just to be clear, we don't want to test if someone can develop on *nix, only that they know their way around the command line).
I was thinking about making them solve a problem of getting information out of log files, which would involve some basics like…
I'm writing a pthread server which takes requests from clients and sends them back a bunch of .ppm files. Everything seems to go well, but sometimes when I have just 1 client connected, when trying to read from the file descriptor (for the file), it says Bad file Descriptor. This doesn't make sense, since my int fd isn't -1,…

In the example above the "span" of 'unix'…
In readline(3) I should be able to map Control-Backspace to the same function as Control-W (unix-kill-rubout). Regardless of what I put in ~/.inputrc I'm unable to get this to be recognized.

Hi. Am a c-coder for a while now - neither a newbie nor an expert. Now, I have a certain daemoned application in C on a PPC Linux.
