+The
+.Fn setattrlistat
+system call is equivalent to
+.Fn setattrlist
+except in the case where
+.Fa path
+specifies a relative path.
+In this case the attributes are set for the file system object named by
+path relative to the directory associated with the file descriptor
+.Fa fd
+instead of the current working directory.
+If
+.Fn setattrlistat
+is passed the special value
+.Dv AT_FDCWD
+in the
+.Fa fd
+parameter, the current working directory is used and the behavior is
+identical to a call to
+.Fn setattrlist .
