Mini-libc

A lightweight and minimal C standard library implementation designed for embedded systems, operating system kernels, and bare-metal applications.

Features

• Minimalistic Implementation – Provides only essential libc functionalities to keep the footprint low.
• Custom Memory Management – Includes a simple malloc() and free() for heap allocation.
• String Handling – Implements core string manipulation functions like memcpy(), strlen(), and strcmp().
• Standard I/O Support – Basic implementations of printf() and puts().
• Optimized for Size and Performance – Designed for environments where resources are limited.
• Portability – Can be adapted for various platforms with minimal modifications.
