Subject: Add an IsAttrib method on the FileEvent struct
X-Git-Tag: v1.7.2~327^2~3
X-Git-Url: https://go.fuhry.dev/?a=commitdiff_plain;h=bd50c45aeddf1be05074364f9b986ad8b6c50b31;p=fsnotify.git

Add an IsAttrib method on the FileEvent struct

This IsAttrib function can be used to distinguish events that only
concern a file's metadata (eg. atime, mtime etc.).
