.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.
This are convience 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 convience 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 .
