通过读取位二进制文​​件位 [英] Reading a binary file bit by bit

问题描述

我知道下面的功能：

size_t fread(void *ptr, size_t size_of_elements, size_t number_of_elements, FILE *a_file);

这只能由字节读取字节，我的目标是能够在一次读取12位，然后带他们到一个数组。任何帮助或指针将不胜AP preciated！

It only reads byte by byte, my goal is to be able to read 12 bits at a time and then take them into an array. Any help or pointers would be greatly appreciated!

推荐答案

添加到第一个评论，你可以尝试每次读一个字节（声明char变量，并写有），然后使用位运算符>>和＆lt;＆LT;逐位读位。在这里阅读更多：<一href=\"http://www.cprogramming.com/tutorial/bitwise_operators.html\">http://www.cprogramming.com/tutorial/bitwise_operators.html

Adding to the first comment, you can try reading one byte at a time (declare a char variable and write there), and then use the bitwise operators >> and << to read bit by bit. Read more here: http://www.cprogramming.com/tutorial/bitwise_operators.html
