Prefs
   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.

  24and contains a number of unit tests as well for testing io_uring. It also
  25comes with man pages for the three system calls.
