Understanding the Role of libc
Brigding the Gap Beetween User Space and Kernel Space in Linux
Embedded Linux systems have become an integral part of our daily lives, powering a wide range of devices such as smartphones, smart home appliances, and industrial equipment. At the heart of these systems lies an essential component known as the C library, or libc.
In this article, we will explore how libc serves as the critical interface between the user space and the kernel space in embedded Linux, enabling seamless communication and providing a foundation for the functionality and performance we rely on.
Some Context About Embedded Linux
Before diving into the specifics of libc, it’s crucial to grasp the basics of embedded Linux.
In embedded systems, the operating system consists of two distinct spaces: user space and kernel space. User space is where applications and processes run, while kernel space is where the operating system’s core functions, device drivers, and hardware interactions take place. The primary role of the C library is to bridge the gap between these two spaces, facilitating communication and ensuring efficient interactions.
