WinAPI is application programming interfaces that is available in Microsoft
Windows operating system. It designs for applications to communicate
with Windows operation system. For example: If you want to create
simple window, you need to send a request to operating system and
operation system will response back weather operating system allow
your application to create window or not. Note that whenever one
application run, operation system will give it one handler to identify
itself. If you want to know which button is pressed in your application
you need to request the operating system and the operating system
will response whenever the key is pressed. It is how the windows
operating system communicate with your application and it is what
WinAPI is using for.... Some of my explaination might not be correct...
but I hope you understand what it is.
