You don't need io_uring for that - the usual synchronous file operations will cause the OS to switch away from processes while they wait for disk, if there are other processes needing to do work. OP's design is for when you have other work to do in the same process.


When I said “runtime” and “program” I meant it. If I had meant process I would probably have used that word.


Okay, I see what you mean. To me "program" usually implies process, even in a runtime.
