我有 fscanf 从配置文件中读取设置行。这些设置具有严格预定义的格式，看起来像
name1=option1;
name2=option2;
...
所以基本上我会
fscanf(configuration,"%[^=]=%[^;];",name,option);
其中配置是文件流，名称和选项是编程缓冲区。
问题是名称缓冲区包含我不想要的换行符。我在“[^...]”设置中错过了格式说明符以跳过换行符吗？无论如何，它可以通过格式说明符解决吗？
顺便说一句：通过写这个来吞下换行符
"%[^=]=%[^;];\n"
我认为这并不优雅，因为换行符可以在任何地方重复多次。
只需在格式字符串的末尾添加空格：
"%[^=]=%[^;]; "
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).
An alternative is to use fgets() to read the entire line into a string, then use sscanf(). This has an advantage in debugging in that you can see exactly what data the function is working on.
这将起作用：
fscanf(configuration,"%[^=]=%[^;];%[^\n]",name,option,dummy);
您将不得不使用换行符。否则，换行符将留在输入流中。
