我正在尝试使用 fseek 查找文件的末尾，一次以 2560 * 5 个字节的步长查找。不知道为什么会出现分段错误，我在 TDA2x 板上运行此代码。这是我不知道的特定环境中的问题吗？

uNumFrames 的起始值为 1000 这段代码基本上是尝试从外部连接的 SSD 驱动器读取数据，并且正在逐字节读取文件，使用 fseek 跳过文件中的某些容器。我面临的问题是，在尝试读取这样的文件时，代码因以下详细信息而崩溃

while(uNumFrames > 500)
{
    logger::addLog(logger::LOGGER_INFO,"Inside while loop, uNumFrames = %d", uNumFrames);
    /*Skip packet Header*/
    ui_skip_count = fseek(fp, HeaderSize * 5, SEEK_CUR);  
    fsize = ftell(fp);
    logger::addLog(logger::LOGGER_INFO,"fsize = %ld\n", fsize);

    if (ferror(fp))
    {
        logger::addLog(logger::LOGGER_INFO,"fseek Error");
        fclose (fp);
        break;
    }

    if(0 != ui_skip_count)
    {
        logger::addLog(logger::LOGGER_INFO,"fseek for fp failed");
    }
    else
    {
        logger::addLog(logger::LOGGER_INFO,"Inside else for read and scale");
    }
    uNumFrames--;
}

示例输出如下所示：
