Please review https://bitbucket.org/dooots/go-sdl2/src/default/sdl/keyboard.go#cl-29 .
from go-sdl2.
import "reflect"
func GetKeyboardState(numkeys *int) []uint8 {
_numkeys := (*C.int) (unsafe.Pointer(numkeys))
start := C.SDL_GetKeyboardState(_numkeys)
sh := reflect.SliceHeader{}
sh.Len = int(*_numkeys)
sh.Cap = int(*_numkeys)
sh.Data = uintptr(unsafe.Pointer(start))
return *(*[]uint8)(unsafe.Pointer(&sh))
}

Yeah, that's definitely better usage and safety wise because there's no separate variable to know the length of the array. It's now using the code from dooots . Thanks!
