fgets()和fread()-有什么区别? [英] fgets() and fread() - What is the difference?

问题描述

我了解 fgets() 和 fgetss() ，但我没有得到 fgets() 和 fread() ，有人可以澄清一下这个主题吗?哪一个更快?谢谢！

I understand the differences between fgets() and fgetss() but I don't get the difference between fgets() and fread(), can someone please clarify this subject? Which one is faster? Thanks!

推荐答案

fgets 读取一行-即它将在换行处停止.

fgets reads a line -- i.e. it will stop at a newline.

fread 读取原始数据-它将在指定的(或默认)个字节数后停止，与可能存在或可能不存在的任何换行符无关.

fread reads raw data -- it will stop after a specified (or default) number of bytes, independently of any newline that might or might not be present.

速度不是一个在另一个上使用的理由，因为这两个功能根本做不到相同的事情:

Speed is not a reason to use one over the other, as those two functions just don't do the same thing :

• 如果您想从文本文件中读取一行，请使用 fgets
• 如果要从文件中读取某些数据(不一定是一行)，请使用

• If you want to read a line, from a text file, then use fgets
• If you want to read some data (not necessarily a line) from a file, then use fread.
