Where are these key codes and state flags coming from?

[akriegman]

So the keycodes don't agree with the virtual keycodes listed here https://learn.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes. Are the Interception keycodes documented or #defined anywhere? Similarly the state field contains some flags. Clearly key_stroke.state | 0x1 is down vs up, but are the other flags documented anywhere?

nevermind I found it https://learn.microsoft.com/en-us/windows/win32/api/winuser/ns-winuser-rawkeyboard

In case it would be useful for anyone, here's some defines for the scan codes, using the same names as in the Linux kernel headers, generated by ChatGPT. On my keyboard these are right up until the key_stroke.state | 0x2 flag is raised.

Edit: I'm an idiot, these are also the same as the values used by the linux kernel. https://github.com/torvalds/linux/blob/master/include/uapi/linux/input-event-codes.h
