These functions create and manipulate data objects that represent entries within
  an archive. You can think of a struct archive_entry as a heavy-duty version of
  struct stat: it includes everything from struct stat plus associated pathname,
  textual group and user names, etc. These objects are used by
  libarchive(3) to represent
  the metadata associated with a particular entry in an archive.
There are functions to allocate, destroy, clear, and copy
  archive_entry objects:
  - archive_entry_clear()
- Erases the object, resetting all internal fields to the same state as a
      newly-created object. This is provided to allow you to quickly recycle
      objects without thrashing the heap.
- archive_entry_clone()
- A deep copy operation; all text fields are duplicated.
- archive_entry_free()
- Releases the struct archive_entry object.
- archive_entry_new()
- Allocate and return a blank struct archive_entry object.
Due to high number of functions, the accessor functions can be found in man
  pages grouped by the purpose.
  - archive_entry_acl(3)
- Access Control List manipulation
- archive_entry_paths(3)
- Path name manipulation
- archive_entry_perms(3)
- User, group and mode manipulation
- archive_entry_stat(3)
- Functions not in the other groups and copying to/from
      struct stat.
- archive_entry_time(3)
- Time field manipulation
Most of the functions set or read entries in an object. Such
    functions have one of the following forms:
  - archive_entry_set_XXXX()
- Stores the provided data in the object. In particular, for strings, the
      pointer is stored, not the referenced string.
- archive_entry_copy_XXXX()
- As above, except that the referenced data is copied into the object.
- archive_entry_XXXX()
- Returns the specified data. In the case of strings, a const-qualified
      pointer to the string is returned.
String data can be set or accessed as wide character strings or normal
  char strings. The functions that use wide character
  strings are suffixed with_w. Note that these are
  different representations of the same data: For example, if you store a narrow
  string and read the corresponding wide string, the object will transparently
  convert formats using the current locale. Similarly, if you store a wide
  string and then store a narrow string for the same data, the previously-set
  wide string will be discarded in favor of the new data.
The libarchive library first appeared in
  FreeBSD 5.3.
