等價的C的Java代碼JNA例如

Question

我喜歡這個 -

文件代碼：input.h

struct Address{ 
     int a; 
     int b; 
    }; 
    void func(struct Address *a);  

什麼是等效JNA Java代碼？

只要這樣的一個界面中從一個抽象的Library或擴展（如果你使用的是Windows）特定的平臺com.sun.jna.win32.StdCallLibrary：

public interface MyLibrary extends Library { 

    /** 
    * Native library instance. 
    */ 
    MyLibrary INSTANCE = (MyLibrary)Native.loadLibrary("MyLibrary", MyLibrary.class); 

    /** 
    struct Address{ 
     int a; 
     int b; 
    };  
    */ 

    public class Address extends Structure { 
     public int a; 
     public int b; 
     public static class ByReference extends Address implements Structure.ByReference { 

     }; 
     public static class ByValue extends Address implements Structure.ByValue { 

     };   
    }; 

    /** 
     void func(struct Address *a); 
    */ 
    void func(Address a); 
}
