* Disabled shared-library building, as some API breakage is still likely. (I didn't realize it was turned on by default.) If you have an existing /usr/lib/libarchive.so.2, I recommend deleting it. * Pax interchange format now correctly stores and reads UTF8 for extended attributes. In particular, pax format can portably handle arbitrarily long pathnames containing arbitrary characters. * Library compiles cleanly at -O2, -O3, and WARNS=6 on all FreeBSD-CURRENT platforms. * Minor portability improvements inspired by Juergen Lock and Greg Lewis. (Less reliance on stdint.h, isolating of various portability-challenged constructs.) * archive_entry transparently converts multi-byte <-> wide character strings, allowing clients and format handlers to deal with either one, as appropriate. * Support for reading 'L' and 'K' entries in standard tar archives for star compatibility. * Recognize (but don't yet handle) ACL entries from Solaris tar. * Pushed format-specific data for format readers down into format-specific storage and out of library-global storage. This should make it easier to maintain individual formats without mucking with the core library management. * Documentation updates to track the above changes. * Updates to tar.5 to correct a few mistakes and add some additional information about GNU tar and Solaris tar formats. Notes: * The basic 'tar' reader is getting more general; there's not much point in keeping the 'gnutar' reader separate. Merging the two would lose a bunch of duplicate code. * The libc ACL support is looking increasingly inadequate for my needs here. I might need to assemble some fairly significant code for parsing and building ACLs. <sigh>

.Sh DESCRIPTION
|
|
These functions create and manipulate data objects that
|
|
represent entries within an archive.
|
|
You can think of a
|
|
.Tn struct archive_entry
|
|
as a heavy-duty version of
|
|
.Tn struct stat :
|
|
it includes everything from
|
|
.Tn struct stat
|
|
plus associated pathname, textual group and user names, etc.
|
|
These objects are used by
|
|
.Xr libarchive 3
|
|
to represent the metadata associated with a particular
|
|
entry in an archive.
|
|
.Pp
|
|
Most of the functions here set or read entries
|
|
in an object. Such functions have one of the
|
|
following forms:
|
|
.Bl -tag -compact -width indent
|
|
.It Fn archive_entry_set_XXXX
|
|
Stores the provided data in the object.
|
|
In particular, for strings, the pointer is stored,
|
|
not the referenced string.
|
|
.It Fn archive_entry_copy_XXXX
|
|
As above, except that the referenced data is copied
|
|
into the object.
|
|
.It Fn archive_entry_XXXX
|
|
Returns the specified data.
|
|
In the case of strings, a const-qualified pointer to
|
|
the string is returned.
|
|
.El
|
|
The string data can be accessed as wide character strings
|
|
(which are suffixed with
|
|
.Cm _w )
|
|
or normal
|
|
.Va char
|
|
strings.
|
|
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.
|
|
.Pp
|
|
The remaining functions allocate, destroy, clear, and copy
|
|
.Va archive_entry
|
|
objects.
|
|
These functions are described below:
|
|
.Bl -tag -compact -width indent
|
|
.It Fn 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.
|
|
.It Fn archive_entry_clone
|
|
A deep copy operation; all text fields are duplicated.
|
|
.It Fn archive_entry_free
|
|
Releases the
|
|
.Tn struct archive_entry
|
|
object.
|
|
.It Fn archive_entry_new
|
|
Allocate and return a blank
|
|
.Tn struct archive_entry
|
|
object.
|
|
.It Fn archive_entry_set_tartype
|
|
Sets the value to be used in a tar-format header
|
|
for this entry.
|
|
Client code should generally not set this; if it
|
|
is left unset, the library will automatically determine
|
|
an appropriate value.
