    std::string fullPath = CCFileUtils::fullPathFromRelativePath("find.txt");
    unsigned char* pBuffer = NULL;
    unsigned long bufferSize = 0;
    pBuffer = CCFileUtils::getFileData(fullPath.c_str(), "r", &bufferSize);
    
    CCLog("%ld",bufferSize); 
    for (int i = 0; i < bufferSize; ++i) 
    {
        CCLog("%c",pBuffer[i]);
    }
