I think the correct C type is used.
refer: https://github.com/ebfe/scard/blob/master/scard_unix.go
Line 57:
func scardGetStatusChange(ctx uintptr, timeout uint32, states
[]scardReaderState) Error {
r := C.SCardGetStatusChange(C.SCARDCONTEXT(ctx), C.DWORD(timeout),
(C.LPSCARD_READERSTATE)(unsafe.Pointer(&states[0])), C.DWORD(len(states)))
return Error(r)
