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. Beejs Guide to Unix IPCBrian “Beej Jorgensen” [email protected] This guide is written in XML using the vim editor on a Slackware.

Also, you can leverage some of the guarantees provided by the kenel’s vfs layer. Or, as troglobit said, TIPC. Has it paid off with an increase in enjoyment?
Making a group specific to the message sending can help. I quite enjoy programming in C, so hopefully that helps.

I keep forgetting that we now have it has an option. I haven’t tried it directly. As, I originally said, though, there is certainly no one-size-fits-all solution, these are just a few of the available options, which may not be apropriate for your situation.
If drops are fine, TIPC is probably overkill. 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. The sender then drains the data it wrote, so that the FIFO becomes unreadable again. Then it works like this: From a little searching it looks like it’s very capable but geared towards clusters, and is overkill for my use case.

The man oage inotify 7 should have an example. My use case is very simple: In general you have to be very careful how you handle it and consider various consistency and failures scenarios. Its amazing how we think the grass is greener.
Uunix add to the chorus of praise for Beej’s work. When messaging becomes gkide complex, there are often other things that impact the overall design in important ways that need need to be considered.
Beej helped me pass my Operating Systems final last semester. The main part of memory layout looks something like this: On OS X there’s notify 3 which is very nice.
Signals can coalesce, but you should never drop any. Any good options on Linux, other than writing my own socket server? One writer writes and multiple readers can observe. Your signals also persist across programs shutdowns and crashes – you can send and receive even when the other side isn’t running – and your state can persist across ot.
This is a total abuse of FIFOs, but it’s proven to be much simpler than trying to manage a separate server. This has an advantage of centralizing any messaging complexity and lets you manage any multi-message state easily. I think there is a gap in the Linux APIs in this area.
Truth be told, a significant portion of my day job is still web application stuff. Thanks for the reply. You can poll a directory that will normally be empty without much CPU load the directory inode will be cached most of the time.
Only the lucky ilc get to hack on databases, hypervisors and file systems for a living! 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. Also check out his guide to C programming [0] and his guide to network programming [1] [0] http: Not fun, but a cost that is sometimes worth paying.
I tried that once, and it was unreliable. Just touch a file in a well-defined directory named after the event that happened, and poll it guie.
