Hi, I'm developing some modular software where it would be very convienent to have a system where a bunch of processes (spanning several languages, some more of a pain to write in than others) share a single queue of text-based event messages.

Conceptually, I could do this with a text file, where all the programs are appending content and iterating through the file line by line, waiting when there is no more left to read. However, that would create an infinite backlog of messages, which I have no need of. It feels like a generic enough problem that it should be solved at the OS level, but I don't know what to call it to begin looking into it.

Is this a solved problem that I can simply find a canned solution for, or do I n Ed to implement something from scratch?
