A collection of programs and examples demonstrating Linux API usage in C, covering essential system calls, file operations, process management, memory handling, and interprocess communication. Ideal for learning and mastering low-level programming on Linux.
This repository contains examples and exercises demonstrating the use of Linux system calls and APIs using C programming. It is intended for students, enthusiasts, and professionals aiming to understand the core of Linux-based system programming.
- File and directory operations (
open,read,write,close,stat, etc.) - Process creation and control (
fork,exec,wait,exit) - Inter-process communication (pipes, message queues, shared memory)
- Memory management (
mmap,brk,malloc, etc.) - Signals and signal handling
- Thread programming using
pthreads - Error handling and debugging tools
file_io/mouse_reader.c: Reads raw mouse events from/dev/input/micefile_io/battery_status.c: Reads battery percentage from/sys/class/...file_io/keyboard_reader.c: Reads keyboard input from/dev/input/eventXfile_io/arg_parser.c: Demonstrates command-line argument handling in C
Ensure you have gcc installed:
sudo apt update
sudo apt install build-essential
To compile a sample program:
gcc file_operations/read_write.c -o read_write
./read_write
