声明struct StuNode* SearchStuNodeByName(struct StuHead *pstHead,char *name);

struct StuNode* SearchStuNodeByName(struct StuHead *pstHead,char *name)
{
    struct StuNode *pstNode = NULL;
    pstNode = pstHead->pstFirst;
    while(pstNode != NULL)
    {
        if(pstNode->data.name == name)
        {
            break;
        }
        pstNode = pstNode->pstNext;
    }
    return pstNode;
}

调用pstNode = SearchStuNodeByName(struct StuHead *pstHead,char *name);//提示在struct前少了一个参数，函数SearchStuNodeByName参数太少
