48 These functions create and manipulate data objects that
49 represent entries within an archive.

52 as a heavy-duty version of
54 it includes everything from
56 plus associated pathname, textual group and user names, etc.
57 These objects are used by
59 to represent the metadata associated with a particular
61 .Ss Create and Destroy
62 There are functions to allocate, destroy, clear, and copy
65 .Bl -tag -compact -width indent
66 .It Fn archive_entry_clear
67 Erases the object, resetting all internal fields to the
68 same state as a newly-created object.
69 This is provided to allow you to quickly recycle objects
70 without thrashing the heap.
71 .It Fn archive_entry_clone
72 A deep copy operation; all text fields are duplicated.
73 .It Fn archive_entry_free
75 .Tn struct archive_entry
77 .It Fn archive_entry_new
78 Allocate and return a blank
79 .Tn struct archive_entry
83 Due to high number of functions, the accessor functions can be found in
84 man pages grouped by the purpose.

99 Most of the functions set or read entries in an object.
100 Such functions have one of the following forms:
101 .Bl -tag -compact -width indent
102 .It Fn archive_entry_set_XXXX
103 Stores the provided data in the object.
104 In particular, for strings, the pointer is stored,
105 not the referenced string.
106 .It Fn archive_entry_copy_XXXX
107 As above, except that the referenced data is copied
109 .It Fn archive_entry_XXXX
110 Returns the specified data.
111 In the case of strings, a const-qualified pointer to
112 the string is returned.
114 String data can be set or accessed as wide character strings
118 The functions that use wide character strings are suffixed with
120 Note that these are different representations of the same data:
121 For example, if you store a narrow string and read the corresponding
122 wide string, the object will transparently convert formats
123 using the current locale.
124 Similarly, if you store a wide string and then store a
125 narrow string for the same data, the previously-set wide string will
126 be discarded in favor of the new data.
