+/* Set the access control lists of a file to match *exactly* MODE (this might
+   remove inherited ACLs). Note chmod() tends to honor inherited/default
+   ACLs. If DESC is a valid file descriptor, use file descriptor operations
+   where available, else use filename based operations on NAME.  If access
+   control lists are not available, fchmod the target file to MODE.  Also
+   sets the non-permission bits of the destination file
+   (S_ISUID, S_ISGID, S_ISVTX) to those from MODE if any are set.
+   Return 0 if successful.  Return -1 and set errno upon failure.  */
