Heres the signature...
uint32_t GetKeyState(
uint32_t stateArrayCount,
GameInputKeyState* stateArray
);The docs say...
stateArrayCount In
Type: uint32_t
Returns the number of keys active on a keyboard. This is acquired by calling the IGameInputReading::GetKeyCount method.
How does it return? This isn't a return, it's a value argument. And I assume this is asking for the size of the StateArray because C++ can't work out the size of arrays in a way that's familiar to modern languages.
