| 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
