在nesc的代码中，你会看到很多你不认识的数据类型，比如uint8_t等。咋一看，好像是个新的数据类型，不过C语言（nesc是C的扩展）里面好像没有这种数据类型啊！怎么又是u又是_t的？很多人有这样的疑问。论坛上就有人问：以*_t结尾的类型是不是都是long型的？在baidu上查一下，才找到答案，这时才发觉原来自己对C掌握的太少。-In nesc code, you will see a lot of you don t know the type of data, such as uint8_t, etc. At first glance, like a new data type, but C (nesc is C extensions) as if there is the data type! How is u _t again? A lot of people have such doubt. On the BBS ask for someone: end with* _t type is long? Check on baidu, to find the answer, then to find that the original master too little to C.
