50 These functions create and manipulate data objects that
51 represent entries within an archive.

54 as a heavy-duty version of
56 it includes everything from
58 plus associated pathname, textual group and user names, etc.
59 These objects are used by

63 .Ss Create and Destroy
64 There are functions to allocate, destroy, clear, and copy
67 .Bl -tag -compact -width indent
68 .It Fn archive_entry_clear
69 Erases the object, resetting all internal fields to the
70 same state as a newly-created object.
71 This is provided to allow you to quickly recycle objects
72 without thrashing the heap.
73 .It Fn archive_entry_clone
74 A deep copy operation; all text fields are duplicated.
75 .It Fn archive_entry_free
77 .Tn struct archive_entry
79 .It Fn archive_entry_new
80 Allocate and return a blank
81 .Tn struct archive_entry
85 Due to high number of functions, the accessor functions can be found in
86 man pages grouped by the purpose.

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