Active Template Library (ATL)

Active Template Library (ATL) is a set of C++ tools designed to help developers create fast, efficient software components called COM objects, which enable different software applications to communicate and work together. It provides reusable code templates and frameworks that simplify the process of building these components, reducing development time and improving performance. Essentially, ATL streamlines the creation of modular, interoperable pieces of software that can be integrated into larger systems, making complex application development more manageable and efficient.
