| 12 | .Sh DESCRIPTION | |
| 13 | The function | |
| 14 | .Fn lchmod | |
| 15 | sets the file permission bits of the file specified by the pathname | |
| 16 | .Fa path | |
| 17 | to | |
| 18 | .Fa mode . | |
| 19 | See | |
| 20 | .Xr chmod 2 | |
| 21 | for the values of the | |
| 22 | .Fa flags . | |
| 23 | .Pp | |
| 24 | The | |
| 25 | .Fn lchmod | |
| 26 | call is like | |
| 27 | .Fn chmod | |
| 28 | except when the named file is a symbolic link, | |
| 29 | in which case | |
| 30 | .Fn lchmod | |
| 31 | will change the flags of the link itself, | |
| 32 | rather than the file it points to. | |
| 33 | .Sh NOTE | |
| 34 | Instead of being a system call, | |
| 35 | .Fn lchmod | |
| 36 | is emulated using | |
| 37 | .Xr setattrlist 2 . | |
| 38 | Not all file systems support | |
| 39 | .Xr setattrlist 2 . | |
| 40 | .Sh RETURN VALUES | |
| 41 | Upon successful completion, a value of 0 is returned. | |
| 42 | Otherwise, -1 is returned and the global variable | |
| 43 | .Va errno | |
| 44 | is set to indicate the error. | |
| 45 | .Sh ERRORS | |
| 46 | The | |
| 47 | .Fn lchmod | |
| 48 | call may return the same errors as | |
| 49 | .Xr chmod 2 | |
| 50 | and | |
| 51 | .Xr setattrlist 2 . | |
