| 4 | .Sh NAME | |
| 5 | .Nm lutimes | |
| 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 . | |
