JNA 中 SHChangeNotify 的正确映射

Question

这是来自 MSDN 的 SHChangeNotify 函数的语法：

void SHChangeNotify(
  LONG wEventId,
  UINT uFlags,
  __in_opt  LPCVOID dwItem1,
  __in_opt  LPCVOID dwItem2
);

我必须在 Java Native Access [JNA] 中编写它的 Java 对应物，但这个声明似乎是错误的：

public interface Shell32 extends com.sun.jna.platform.win32.Shell32 {

    public Shell32 INSTANCE = (Shell32) Native.loadLibrary(Shell32.class);

    void SHChangeNotify(long wEventId, int uFlags, Pointer dwItem1, Pointer dwItem2);

}

我遇到了以下异常：

线程“主”java.lang.UnsatisfiedLinkError 中的异常：错误 查找函数“SHChangeNotify”

知道如何正确写吗？

不是从com.sun.jna.platform.win32.Shell32扩展Shell32接口，而是从StdCallLibrary扩展它

public interface Shell32 extends StdCallLibrary {
    final static Map<String, Object> WIN32API_OPTIONS = new HashMap<String, Object>() {
        private static final long serialVersionUID = 1L;
        {
            put(Library.OPTION_FUNCTION_MAPPER, W32APIFunctionMapper.UNICODE);
            put(Library.OPTION_TYPE_MAPPER, W32APITypeMapper.UNICODE);
        }
    };

    public Shell32 INSTANCE = (Shell32) Native.loadLibrary("Shell32", Shell32.class, WIN32API_OPTIONS);

    //whatever you want to expose here
}
