| 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 |
