| This directory includes a few programs that demonstrate how to use io_uring | |
| in an application. The examples are: | |
| io_uring-cp | |
| A very basic io_uring implementation of cp(1). It takes two | |
| arguments, copies the first argument to the second. This example | |
| is part of liburing, and hence uses the simplified liburing API | |
| for setting up an io_uring instance, submitting IO, completing IO, | |
| etc. The support functions in queue.c and setup.c are straight | |
| out of liburing. | |
| io_uring-bench | |
| Benchmark program that does random reads on a number of files. This | |
| app demonstrates the various features of io_uring, like fixed files, | |
| fixed buffers, and polled IO. There are options in the program to | |
| control which features to use. Arguments is the file (or files) that | |
| io_uring-bench should operate on. This uses the raw io_uring | |
| interface. | |
| liburing can be cloned with git here: | |
| git://git.kernel.dk/liburing | |
| and contains a number of unit tests as well for testing io_uring. It also | |
| comes with man pages for the three system calls. | |
| Fio includes an io_uring engine, you can clone fio here: | |
| git://git.kernel.dk/fio |
