+/* Set the access and modification time stamps of FD (a.k.a. FILE) to be
+ TIMESPEC[0] and TIMESPEC[1], respectively; relative to directory DIR.
+ FD must be either negative -- in which case it is ignored --
+ or a file descriptor that is open on FILE.
+ If FD is nonnegative, then FILE can be NULL, which means
+ use just futimes (or equivalent) instead of utimes (or equivalent),
+ and fail if on an old system without futimes (or equivalent).
+ If TIMESPEC is null, set the time stamps to the current time.
+ ATFLAG is passed to utimensat if FD is negative or futimens was
+ unsupported, which can allow operation on FILE as a symlink.
+ Return 0 on success, -1 (setting errno) on failure. */
