Basics of the Windows API
The Windows Application Programming Interface (API), also known as Win32 or WinAPI, is a collection of libraries, functions, and interfaces that provide low-level access to various features and components of the Windows operating system. It allows developers direct access to system features and hardware, simplifying access to deeper layers of the operating system. The Windows API functions are written in C/C++ and are exposed by DLL files (such as kernel32.dll or user32.dll).
The Windows API is implemented as a collection of dynamic-link libraries (DLLs) that are loaded into memory when an application needs to use them. These DLLs contain the functions and procedures that make up the API. When an application calls a function from the API, it is essentially sending a message to the operating system to perform a certain task. The operating system then executes the appropriate function from the appropriate DLL and returns the result to the application.
