Apache flex Adobe Alchemy字节数组读取问题

我试图将从文件中提取的字节数组发送到C代码，并再次从C代码返回该字节数组

我正在文本视图contents.text中打印C返回值的内容，但我能看到的只是字节数组对象OggS。我看不到字节数组的内容。谁能说我哪里出了问题？。。我已经发布了C代码和AS代码

AS Code:
 private function copyByteArray(content:String):void{

        try{

        byteData = new ByteArray();
        //byteData.writeUTFBytes(contents);
        var dec:Base64Decoder = new Base64Decoder();
        dec.decode(content);
        byteData = dec.toByteArray();
        //Alert.show("byte Array   " + byteData +" ::  " +contents.length);

        var file:File = File.desktopDirectory.resolvePath("Files/test.spx");
        stream = new FileStream();
        stream.open(file, FileMode.WRITE);


      /*  var loader:CLibInit = new CLibInit();
        var lib:Object = loader.init();
        loader.supplyFile("testFile.txt", byteData);
        contents.text = lib.sqre(5);*/

        var loader:CLibInit = new CLibInit();
        var lib:Object = loader.init();
    //  var result:String = lib.doMagic(byteData);




        var byteArr:ByteArray;
        var byteStr:String;
    //byteArr.writeBytes(byteData, 0 , byteData.length);

    loader.supplyFile("test1.txt" , byteData);
    byteStr = lib.readFile("test1.txt");
    contents.text = byteStr;


    //stream.writeBytes();
        stream.close();

    }
    catch (ex: ErrorEvent){
        Alert.show("error");

    }
}

C代码：

static AS3_Val readFile(void* self, AS3_Val args)
{
    char * fileName;
    FILE * file;
    long fileSize;
    char * buffer;

    AS3_ArrayValue(args, "StrType", &fileName);

    file = fopen(fileName,"rb");

    //Get file size
    fseek (file, 0, SEEK_END);
    fileSize = ftell(file);
    rewind(file);

    //Allocate buffer
    buffer = (char*) malloc(sizeof(char)*fileSize);

    //Read file into buffer
    fread(buffer, 1, fileSize, file);

    //close file and free allocated buffer
    fclose (file);
    free (buffer);

    return AS3_String((char*)buffer);
}

static AS3_Val readFile( void *self, AS3_Val args ) {

    AS3_Val inData_arg = AS3_Undefined();
    AS3_Val outData_arg = AS3_Undefined();
    AS3_ArrayValue( args, "AS3ValType, AS3ValType", &inData_arg, &outData_arg );

    AS3_Val inDataLength = AS3_GetS( inData_arg, "length" );

    -- do something with input data, fill output data array

    // try to stop it leaking    
    // AS3_ReleaseX( wavData_arg ); AS3_ReleaseX( dstData_arg ); AS3_ReleaseX( logFile_arg );
    // AS3_ReleaseX( args );
    return AS3_Null;
}

我也有点被困在这个问题上了。我想到的最好的方法是将所有需要的ByteArray传递到c函数中。在我的例子中，我传递一个输入数据字节数组，并传入另一个空byteArray，以便c函数将输出数据放入其中。然后，c函数不需要创建byteArray，我无法让它工作，c函数也不需要返回值

作为代码：

public function actionscriptFunction() {

    var myInputData:ByteArray = new ByteArray();
    -- maybe load a file or something into myInputData

    var myOutputData:ByteArray = new ByteArray();

    var loader:CLibInit = new CLibInit();
    var lib:Object = loader.init();
    lib.readFile( myInputData, myOutputData );

    -- do something with the output data
}

C代码：

static AS3_Val readFile(void* self, AS3_Val args)
{
    char * fileName;
    FILE * file;
    long fileSize;
    char * buffer;

    AS3_ArrayValue(args, "StrType", &fileName);

    file = fopen(fileName,"rb");

    //Get file size
    fseek (file, 0, SEEK_END);
    fileSize = ftell(file);
    rewind(file);

    //Allocate buffer
    buffer = (char*) malloc(sizeof(char)*fileSize);

    //Read file into buffer
    fread(buffer, 1, fileSize, file);

    //close file and free allocated buffer
    fclose (file);
    free (buffer);

    return AS3_String((char*)buffer);
}

static AS3_Val readFile( void *self, AS3_Val args ) {

    AS3_Val inData_arg = AS3_Undefined();
    AS3_Val outData_arg = AS3_Undefined();
    AS3_ArrayValue( args, "AS3ValType, AS3ValType", &inData_arg, &outData_arg );

    AS3_Val inDataLength = AS3_GetS( inData_arg, "length" );

    -- do something with input data, fill output data array

    // try to stop it leaking    
    // AS3_ReleaseX( wavData_arg ); AS3_ReleaseX( dstData_arg ); AS3_ReleaseX( logFile_arg );
    // AS3_ReleaseX( args );
    return AS3_Null;
}

然而，无论我怎么做，这都会泄露秘密，所以我认为一定有更好的办法

**更新

我发现，如果我多次创建一个新的CLibInit，它只会泄漏bytearray。也就是说，如果使用一个静态实例，并且只在一切正常后初始化它

例如
