Specify required argument types for FFI functions

Browse Source 
On arm64 macOS, variadic arguments have special calling convention rules.
Therefore, we must specify the required argument types for ctypes to 
pass the arguments correctly.

Apple documentation: https://developer.apple.com/documentation/xcode/writing-arm64-code-for-apple-platforms#Update-Code-that-Passes-Arguments-to-Variadic-Functions
