  106. .Sh DESCRIPTION
  107. Path names supported by
  108. .Xr archive_entry 3 :
  109. .Bl -tag -width "sourcepath" -compact
  110. .It hardlink
  111. Destination of the hardlink.
  112. .It link
  113. Update only.
  114. For a symlink, update the destination.
  115. Otherwise, make the entry a hardlink and alter
  116. the destination for that.
  117. .It pathname
  118. Path in the archive
  119. .It sourcepath
  120. Path on the disk for use by
  121. .Xr archive_read_disk 3 .
  122. .It symlink
  123. Destination of the symbolic link.
  124. .El
  125. .Pp
  126. Path names can be provided in one of three different ways:
  127. .Bl -tag -width "wchar_t *"
  128. .It char *
  129. Multibyte strings in the current locale.
  130. .It wchar_t *
  131. Wide character strings in the current locale.
  132. The accessor functions are named
  133. .Fn XXX_w .
  134. .It UTF-8
  135. Unicode strings encoded as UTF-8.
  136. This are convience functions to update both the multibyte and wide
  137. character strings at the same time.
  138. .El
  139. .Pp
  140. The sourcepath is a pure filesystem concept and never stored in an
  141. archive directly.
  142. .Pp
  143. For that reason, it is only available as multibyte string.
  144. The link path is a convience function for conditionally setting
  145. hardlink or symlink destination.
  146. It doesn't have a corresponding get accessor function.
  147. .Pp
  148. .Fn archive_entry_set_XXX
  149. is an alias for
  150. .Fn archive_entry_copy_XXX .
