逐位读取二进制文件 [英] Reading a binary file bit by bit
本文介绍了逐位读取二进制文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我知道下面的函数:
size_t fread(void *ptr, size_t size_of_elements, size_t number_of_elements, FILE *a_file);
它只能逐字节读取，我的目标是能够一次读取 12 位，然后将它们放入一个数组中.任何帮助或指点将不胜感激！
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
添加到第一个注释，你可以尝试一次读取一个字节(声明一个char变量并在那里写入)，然后使用位运算符>>和<<一点一点地阅读.在此处阅读更多信息: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
