Given a *uint8 from state how do I test if a scancode is pressed?

http://wiki.libsdl.org/SDL_GetKeyboardState

I can do state := sdl.GetKeyboardState(nil), but then state is a pointer. Should this api be a map so I can test using a key such as SDL_SCANCODE_RETURN?

Please review https://bitbucket.org/dooots/go-sdl2/src/default/sdl/keyboard.go#cl-29 .

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!
