fscanf和换行符 [英] fscanf and newline character

问题描述

我有fscanf从配置文件中读取设置的行。这些设置具有严格的预定义格式，如

  name1 = option1; 
 name2 = option2; 
 ... 
  

所以基本上我做了

  fscanf（configuration，％[^ =] =％[^;];，name，option）; 
  

其中配置是文件流，名称和选项是编程缓冲区。 b

问题是名称缓冲区包含我不想要的换行符。有没有格式说明符我已经错过了[^ ...]设置为跳过换行符？无论如何，它可以通过格式说明符来解决吗？

顺便说一句：通过写这个字符来吞并换行符

 ％[^ =] =％[^;]; \\\

  

是不是elegent我认为换行符可以重复不止一次。

格式字符串的结尾：

 ％[^ =] =％[^;];
  
 
 
这将会包含所有空格字符，包括换行符。
 
 
 
来自 cplusplus.com 的报价：
 
空格字符：函数将读取并忽略在下一个非空白字符（空格字符包括空格，换行符和制表符 - 见isspace）之前遇到的任何空格字符。格式字符串中的单个空格验证从流中提取的任何数量的空白字符（包括none）。 
 
 
I have fscanf to read lines of setting from a configuration file. Those settings have strictly predefined format which looks like
name1=option1;
name2=option2;
...
so basically I do
fscanf(configuration,"%[^=]=%[^;];",name,option);
where configuration is the file stream and name and option are programming buffers.

The problem is that the name buffer contains a newline character I don't want. Is there format specifier I've missed in the "[^...]" set to skip newline character? Anyway, can it be solved through format specifier ever?

BTW: Swallowing the newline character by writting this 
"%[^=]=%[^;];\n"
is not elegent I think for that the newline character could repeat more than once anywhere.
解决方案
Just add space at the end of the format string:
"%[^=]=%[^;]; "
This will eat all whitespace characters, including new-lines.

Quotation from cplusplus.com:

  
Whitespace character: the function will read and ignore any whitespace characters encountered before the next non-whitespace character (whitespace characters include spaces, newline and tab characters -- see isspace). A single whitespace in the format string validates any quantity of whitespace characters extracted from the stream (including none).
