This repository contains a C program that demonstrates the usage of io_uring for asynchronous I/O operations on Linux, specifically designed to run on Ubuntu 22.04.

Before building and running this project, you need to install liburing and PkgConfig on Ubuntu 22.04 to handle the asynchronous I/O capabilities and manage library paths.

PkgConfig is a helper tool used when compiling applications and libraries. It helps you insert the correct compiler options on the command line so an application can use gcc -o test test.c $(pkg-config --libs --cflags glib-2.0) for instance.

To install PkgConfig, open a terminal and run:

sudo apt update
sudo apt install pkg-config

liburing provides an easier and more straightforward way to use Linux kernel's io_uring interface.

To install liburing, execute:

sudo apt update
sudo apt install liburing-dev

Once the prerequisites are installed, you can build the program using CMake. Here's how to set it up:

1. Clone the Repository

   First, clone this repository to your local machine:

   git clone [email protected]:TSWorld1314/IO_Uring-Example.git
   cd IO_Uring-Example

2. Create a Build Directory

   Create a separate build directory for CMake:

   mkdir build
   cd build

3. Configure the Project

   Configure the project using CMake. Specify a debug build to include debug symbols:

   cmake .. -DCMAKE_BUILD_TYPE=Debug

4. Compile the Project

   Compile the project using the generated Makefile:

   cmake --build .

5. Run the Program

   After building the project, you can run the program directly:

   ./io_uring_example  ../hello.txt
