ABI
ABI (Application Binary Interface) is a low-level interface specification that defines how binary code interacts at the machine level, including data types, calling conventions, and system calls. It ensures compatibility between compiled programs and the operating system or libraries, enabling different software components to work together seamlessly. This concept is crucial in systems programming, compiler design, and cross-platform development.
Developers should learn ABI when working on systems programming, embedded systems, or cross-platform applications to ensure binary compatibility and interoperability. It is essential for debugging low-level issues, writing compilers or linkers, and integrating libraries or kernel modules, as it governs how code executes on specific hardware and operating systems.
