MultiKB

Simple windows functions to read seperate input from multiple keyboards

Usage:

Setup:

Call mkb_init() to setup internal things and allocate memory.
Only one instance of this is allowed. I made that questionable design choice of allowing multiple instances of this last time.
There is no need for this to even support multiple instances, because this manages ALL of the keyboards on the system.

Update Loop:

The mkb_update() function runs a message loop to get key changed messages, then sets lastState to state for each key (used to tell if a key was just changed).
It returns:
mkb_DEVICE_NONE (0) if no devices were changed
mkb_DEVICE_CONNECT (1) if a new device was added
mkb_DEVICE_RECONNECT (2) if the new device has the same name as a previous device
mkb_DEVICE_DISCONNECT (3) if a device was removed
The function mkb_getLastEvent() returns the same thing.

Use mkb_getLatestDevice() to get the index of the last device changed.
Use mkb_deviceCount() to get the total device count (including disconnected devices).
Use mkb_deviceConnectedCount() to get the active device count (excluding disconnected devices).
The device index does not shift over when a device is removed,
because the project I am making this for uses keyboards like controllers, and shifting the player indexes would mess up many things.
Use mkb_getNthDevice() to get the index of the nth device.
Ex: mkb_getNthDevice(0) -> 2 the index of the first device is 2.

Key States:

mkb_key() gets the current key state.
mkb_keyLast() gets the last key state.
mkb_keyDown() gets if the key was just pressed (state && !lastState).
mkb_keyUp() gets if the key was just released (!state && lastState).

Shutdown:

Call mkb_shutdown() to free memory when you are done.
To use this again, you have to call mkb_init() again.

Extras:

The key codes are aligned to the ascii table, so you can use a character instead of the key name. (Uppercase)
The array mkb_keyNames contains key names made for displaying to users.
I used to allow capslock and numloc keys to toggle, but they are global states, so that didn't end up being helpful.

C++ Wrapper:

MultiKB class
It is just a very thin wrapper.
It just calls the C functions, nothing else, only one instance will work
It doesn't do anything different, just some people are very unhappy about touching C at all :(
