6 .Nd set file access and modification times of symlink

7 .Sh SYNOPSIS

8 .In sys/time.h

9 .Ft int

10 .Fn lutimes "const char *path" "struct timeval times[2]"

11 .Sh DESCRIPTION

12 The access and modification times of the file named by

13 .Fa path

14 are changed as specified by the argument

15 .Fa times ,

16 even if

17 .Fa path

18 specifies a symbolic link (for

19 .Xr utimes 2

20 the times of the file referenced by the symbolic link are changed).

21 .Pp

22 If

23 .Fa times

24 is

25 .Dv NULL ,

26 the access and modification times are set to the current time.

27 The caller must be the owner of the file, have permission to

28 write the file, or be the super-user.

29 .Pp

30 If

31 .Fa times

32 is

33 .Pf non- Dv NULL ,

34 it is assumed to point to an array of two timeval structures.

35 The access time is set to the value of the first element, and the

36 modification time is set to the value of the second element.

37 The caller must be the owner of the file or be the super-user.

38 .Pp

39 In either case, the inode-change-time of the file is set to the current

40 time.

41 .Sh NOTE

42 Instead of being a system call,

43 .Fn lutimes

44 is emulated using

45 .Xr setattrlist 2 .

46 Not all file systems support

47 .Xr setattrlist 2 .

48 .Sh RETURN VALUES

49 Upon successful completion, a value of 0 is returned.

50 Otherwise, -1 is returned and the global variable

51 .Va errno

52 is set to indicate the error.

53 .Sh ERRORS

54 The

55 .Fn lutimes

56 call may return the same errors as

57 .Xr utimes 2

58 and

59 .Xr setattrlist 2 .
