Beej’s Guide to Unix Interprocess Communication. Version (May). Intro. You know what’s easy? fork() is easy. You can fork off new processes all. I owe my career to Beej. I was getting burnt out of web development and his guides (along with Jesse Storimer’s books) made programming fun.

AddMatch on the message bus which match the signal. Has it paid off with guid increase in enjoyment? This has an advantage of centralizing any messaging complexity and lets you manage any multi-message state easily. Its amazing how we think the grass is greener.

Really quality and entertaining guides he puts together. Also, note these counters also function as total counts of items written and so each reader cand determine how far ahead the writer is.

Classic signals are tricky There’s a variety of options if I’m willing to poll, including shared memory or the filesystem idea you outline, but I hope to avoid polling for hygienic reasons. I’ll add to the chorus of praise for Beej’s work. How did you go about making the switch from web to systems? Even when the problems and tools we use to solve those problems never change, we still somehow get upset with the tools or the problems.

Thanks for reminding me, I really need to put this into practice, so much great stuff in here. Your signals also persist across programs shutdowns and crashes – guidw can send and receive even when the other side isn’t running – and your state can persist across reboots.

Actually both of you are right. You could setup a multiple listeners by giving them their own “inbox” directory, like. Thank you for this thoughtful reply.

beeu Rebroadcasting messages to allow peer-to-peer messaging would be a trivial addition. For example, if I was implementing something that is usually associated with user events geej, basically zero bandwidth, complex signal with stateful messaging semanticsI would probably just write a simple server to manage it all. I haven’t tried it directly. Removing the file clears the flag. Thanks for the reply. The use of poll 2 is just a consequence of the interface using a file handle. My use case is very simple: Perhaps exchanging your jobs with one another might help.

For something that requires very low latency e. Hacker News new comments show ask jobs submit.

I quite enjoy programming in C, so hopefully that helps. I think there is a gap in the Linux APIs in this area. Not fun, but a cost that is sometimes worth paying.

Any good options on Linux, other than writing my own socket server? Also, you can leverage some of the guarantees provided by the kenel’s vfs layer.

But, you might be reading data you didn’t expect. Truth be told, a significant portion of my day job is still web unkx stuff. It’s a lot of fun and opens up a whole new world of programming! Its multicast IPC mechanisms are just too heavyweight.

That’s why I like inotify in blocking mode – the call to poll is just to wake up the process I think you could just blocking-read the inotify file handle?
