构建一个嵌入式系统时

/* 
分级别打印的头文件，包括分级打印的宏定义。

    lpt(lv, ptString)
        task     :打印的任务
        lv       :打印级别
        ptString :打印字符串内容

    lpt1(lv, ptString, para)
        带有一个参数的打印。
        
    lpt2(lv, ptString, para1，para2)
        带有一个参数的打印。

    lpt3(lv, ptString, para1, para2, para3)
        带有一个参数的打印。
