这个怎么去查问题原因啊。
------解决方案--------------------------------------------------------
单步执行你的任务，看执行到哪一步出错
------解决方案--------------------------------------------------------
如果单步执行不方便，在任务重插桩打印信息，看打印到那个地方就报错
------解决方案--------------------------------------------------------
1.先看传入的参数是否正确，调用方法是否正确？
2.如果确定是对方驱动库有问题，就要对方的技术支持了！
这种错误在vxworks下比较常见！
