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 :
- 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
.
