P.S: compile時需加上-std=c++11, 如g++ test.cpp -std=c++11 原文可參考:http://www.badprog.com/c-type-what-are-uint8-t-uint16-t-uint32-t-and-uint64-t

好的,下面我将分别演示按3、1、1、1、5、5位存储的 uint16_t 数据在大端和小端模式下的存储情况。假设有以下结构体定义: #include <stdio.h> #include <stdint.h> t

Do you mean I have to assign my variable to unsigned int variable and then I have to pass it to the function? Pavel A suggested that you pass the member of the union that is an unsigned int. Changes to the value of this union member (foo) will be reflected in the uint16_t ...
这两个CRC计算算法都使用了相同的多项式0x1021(CRC-16 polynomial: x^16 + x^12 + x^5 + 1),并且初始值也都是0xFFFF。在每一位进行异或计算后,都将结果左移一位。 根据这些代码,无论是calculateCRC()还是get_crc_data()函数,最终返回的结果都是 CRC-16 校验码。没有直接返回结果的异或操作。
