JNA - 帶void *參數的回調方法

我有一個C方法，它向供應商提供的dll註冊回調方法。我被告知該DLL在其創建和控制的單獨線程上進行回調。有3種可能的不同數據消息可以通過接收回調接收。JNA - 帶void *參數的回調方法

// Register user receive callback function 
int PTOAPI_MODE PTOregReceivedCB(void (__stdcall *pUsrFunc3)(void* lpData,int iDataLen));

我已經使用JNAERATOR創建已低於段代碼生成的Java接口的代碼，

/// <i>native declaration : Ptsptoext.h:728</i> 
    public interface pUsrFunc3 extends Callback { 
     void invoke(Pointer lpData, int iDataLen); 
    } 

    /** 
    * Original signature : <code>PTOregReceivedCB(pUsrFunc3)</code><br> 
    * <i>native declaration : Ptsptoext.h:728</i> 
    */ 
    @Mangling({"_Z16PTOregReceivedCBPFvPviE", "[email protected]@[email protected]@Z"}) 
    int PTOregReceivedCB(TofapiLibrary.pUsrFunc3 arg3);

我已經跑在簡單main方法的代碼，以確保我可以從DLL是得到回調如下所示。

main(){ 
... 
     success = tofLib.PTOregReceivedCB(new TofapiLibrary.pUsrFunc3() { 

      @Override 
      synchronized public void invoke(Pointer lpData, int iDataLen) { 
       System.out.println("PTOregRecievedCB has been called with data lenght = " + iDataLen); 
      } 
     }); 
..... 
}

當我運行我的測試，它成功地註冊與DLL的回調。但後來當DLL嘗試調用回調方法時，即使在JAVA中的回調方法出現之前，jvm也會崩潰。異常報告顯示「0x0b543a46」處的指令引用「0x0651acc」處的內存，內存不能被「讀取」。我懷疑回調中的指針失敗。你能看到我的代碼有什麼問題嗎？有什麼我需要的回調中的指針對象？我無法讀取JVM崩潰時生成的下面的異常報告。對你的幫助表示感謝。

與void *的參數JNA問題 – user376143 2010-06-29 08:32:29

你需要保持一個強大的參考java的回調對象，否則會得到垃圾收集，並在本機代碼試圖調用它的JVM會崩潰。參見https://jna.dev.java.net/javadoc/com/sun/jna/Callback.html

例如這會將該回調的引用存儲在類中的靜態var中。

static final TofapiLibrary.pUsrFunc3 myCallback = new TofapiLibrary.pUsrFunc3() { 

     @Override 
     synchronized public void invoke(Pointer lpData, int iDataLen) { 
      System.out.println("PTOregRecievedCB has been called with data lenght = " + iDataLen); 
     } 
};

在你的主代碼後，就做：

tofLib.PTOregReceivedCB(myCallback);
