关于第三个参数flags当为FNM_NOESCAPE,man page里：
FNM_NOESCAPE
If this flag is set, treat backslash as an ordinary character, instead of an escape character.
查到资料：
If FNM_NOESCAPE is not set in flags, a backslash character ( '' ) in pattern followed by any other character shall match that second character in string. In particular, "\" shall match a backslash in string. If FNM_NOESCAPE is set, a backslash character shall be treated as an ordinary character.
若pattern是'aq'
string是'aq'
我理解是如果未设置FNM_NOESCAPE,则二者是匹配的，如果设置了就不匹配。结果是不论是否设置都匹配，那到底参数FNM_NOESCAPE是怎么使用？能不能举个例子

如果设了,表明""是个转义符;如果没有设,""就不当作转义符,当作个普通字符.
若pattern是'aq',string是'aq',自然两种都不匹配
