자바 JNA는의 Kernal32에서 명명 된 파이프 기능을 찾을 수 없습니다

Question

그래서이 "음"기능이 작동하지만, 내가 명명 된 파이프 기능 중 하나를 시도 할 때 반환이 :

Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'WaitNamedPipe': The specified procedure could not be found.

import com.sun.jna.Library;

    public interface Kernel32 extends Library {

public boolean WaitNamedPipe(String lpNamedPipeName, 
     int nTimeOut); 
public boolean Beep(int FREQUENCY, int DURATION); 
    } 

    /**

    public static void main(String[] args) { 
     // TODO Auto-generated method stub 
     myClass myclass = new myClass() ; 
     myClass myclass2 = new myClass() ; 

     Pointer lpOutBuffer = myclass.getPointer() ; 
     Pointer lpBytesRead =myclass2.getPointer() ; 

     Kernel32 lib = (Kernel32) Native.loadLibrary("kernel32", Kernel32.class); 
     //lib.CallNamedPipe("1234TestPipe", 255, 255, lpOutBuffer , 255, lpBytesRead , 5000); 
     lib.Beep(698, 500); // works 
     boolean sucess = lib.WaitNamedPipe("hgf" ,(int) 5000); // does not work 

    } 

}

WaitNamedPipe가 정의 #입니다 중 하나입니다 WaitNamedPipeA 또는 WaitNamedPipeW 호출자가 각각 ANSII 또는 UNICODE를 사용하는지 여부에 따라 다릅니다. Source (유니 코드 및 ANSI 이름 섹션 참조) : https://msdn.microsoft.com/en-us/library/windows/desktop/aa365800(v=vs.85).aspx
