30 /* Set the access and modification timestamps of FD (a.k.a. FILE) to be -

31 TIMESPEC[0] and TIMESPEC[1], respectively; relative to directory DIR. -

32 FD must be either negative -- in which case it is ignored -- -

33 or a file descriptor that is open on FILE. -

34 If FD is nonnegative, then FILE can be NULL, which means -

35 use just futimes (or equivalent) instead of utimes (or equivalent), -

36 and fail if on an old system without futimes (or equivalent). -

37 If TIMESPEC is null, set the timestamps to the current time. -

38 ATFLAG is passed to utimensat if FD is negative or futimens was -

39 unsupported, which can allow operation on FILE as a symlink. -

40 Return 0 on success, -1 (setting errno) on failure. */ -
