README (1112B)
1This directory includes a few programs that demonstrate how to use io_uring 2in an application. The examples are: 3 4io_uring-cp 5 A very basic io_uring implementation of cp(1). It takes two 6 arguments, copies the first argument to the second. This example 7 is part of liburing, and hence uses the simplified liburing API 8 for setting up an io_uring instance, submitting IO, completing IO, 9 etc. The support functions in queue.c and setup.c are straight 10 out of liburing. 11 12io_uring-bench 13 Benchmark program that does random reads on a number of files. This 14 app demonstrates the various features of io_uring, like fixed files, 15 fixed buffers, and polled IO. There are options in the program to 16 control which features to use. Arguments is the file (or files) that 17 io_uring-bench should operate on. This uses the raw io_uring 18 interface. 19 20liburing can be cloned with git here: 21 22 git://git.kernel.dk/liburing 23 24and contains a number of unit tests as well for testing io_uring. It also 25comes with man pages for the three system calls. 26 27Fio includes an io_uring engine, you can clone fio here: 28 29 git://git.kernel.dk/fio
