0001 This directory includes a few programs that demonstrate how to use io_uring
0002 in an application. The examples are:
0003
0004 io_uring-cp
0005 A very basic io_uring implementation of cp(1). It takes two
0006 arguments, copies the first argument to the second. This example
0007 is part of liburing, and hence uses the simplified liburing API
0008 for setting up an io_uring instance, submitting IO, completing IO,
0009 etc. The support functions in queue.c and setup.c are straight
0010 out of liburing.
0011
0012 io_uring-bench
0013 Benchmark program that does random reads on a number of files. This
0014 app demonstrates the various features of io_uring, like fixed files,
0015 fixed buffers, and polled IO. There are options in the program to
0016 control which features to use. Arguments is the file (or files) that
0017 io_uring-bench should operate on. This uses the raw io_uring
0018 interface.

0020 liburing can be cloned with git here:
0021
0022 git://git.kernel.dk/liburing
0023
0024 and contains a number of unit tests as well for testing io_uring. It also
0025 comes with man pages for the three system calls.
0026
0027 Fio includes an io_uring engine, you can clone fio here:
0028
0029 git://git.kernel.dk/fio
