在C / C ++ scanf（）扫描集中指定']'字符

Question

I would like to use a scanf family function to extract a string delimited by ']'. For a delimiter of ')' one can do this:

scanf(" %80[^)]", &buf); 

But how do you include the ']' in the scanset in general (not just the negated set case example above)? Is there some kind of escape seq for that?

"[^\\]]"

?

诀窍是将']'作为模式中的第一个字符：

scanf(" %80[^]]", &buf);
