lua_pcall函数的文档：

If msgh is 0, then the error object returned on the stack is exactly the original error object. Otherwise, msgh is the stack index of a message handler. (This index cannot be a pseudo-index.) In case of runtime errors, this handler will be called with the error object and its return value will be the object returned on the stack by lua_pcall.

大家看这里， this handler will be called with the error object and its return value will be the object returned on the stack by lua_pcall.

error objec是什么？？？？什么类型？？艹你妈的不能说清楚啊？

后边its return value，it是指？？你他妈不会说话是吧，傻逼！
