.Sh DESCRIPTION
|
|
Path names supported by
|
|
.Xr archive_entry 3 :
|
|
.Bl -tag -width "sourcepath" -compact
|
|
.It hardlink
|
|
Destination of the hardlink.
|
|
.It link
|
|
Update only.
|
|
For a symlink, update the destination.
|
|
Otherwise, make the entry a hardlink and alter
|
|
the destination for that.
|
|
.It pathname
|
|
Path in the archive
|
|
.It sourcepath
|
|
Path on the disk for use by
|
|
.Xr archive_read_disk 3 .
|
|
.It symlink
|
|
Destination of the symbolic link.
|
|
.El
|
|
.Pp
|
|
Path names can be provided in one of three different ways:
|
|
.Bl -tag -width "wchar_t *"
|
|
.It char *
|
|
Multibyte strings in the current locale.
|
|
.It wchar_t *
|
|
Wide character strings in the current locale.
|
|
The accessor functions are named
|
|
.Fn XXX_w .
|
|
.It UTF-8
|
|
Unicode strings encoded as UTF-8.
|
|
These are convenience functions to update both the multibyte and wide
|
|
character strings at the same time.
|
|
.El
|
|
.Pp
|
|
The sourcepath is a pure filesystem concept and never stored in an
|
|
archive directly.
|
|
.Pp
|
|
For that reason, it is only available as multibyte string.
|
|
The link path is a convenience function for conditionally setting
|
|
hardlink or symlink destination.
|
|
It doesn't have a corresponding get accessor function.
|
|
.Pp
|
|
.Fn archive_entry_set_XXX
|
|
is an alias for
|
|
.Fn archive_entry_copy_XXX .
