How to detect if caps lock is already active? [duplicate]

Question

Supposing I want to detect if the caps lock is active so if the keys are upper case, what can I use in c++ with windows?

I would need an equivalent of Console.CapsLock in C#

I already tried using GetAsyncKeyState(VK_CAPITAL) but I don't need the key state I need to know the "toggle" status

Answer 1

The return value from GetKeyState (Win32) has a low order bit (least significant bit) which gives its current toggle status.

If the bit is 1, then the key is toggled. But if it is 0, then the key is not toggled.
