|
|
|
|
|
These functions set the format that will be used for the archive.

The library can write
|
|
|
|
|
POSIX octet-oriented cpio format archives,
|
|
|
|
|
POSIX-standard
|
|
|
|
|
.Dq pax interchange
|
|
|
|
|
format archives,
|
|
|
|
|
traditional
|
|
|
|
|
.Dq shar
|
|
|
|
|
archives,
|
|
|
|
|
enhanced
|
|
|
|
|
.Dq dump
|
|
|
|
|
shar archives that store a variety of file attributes and handle binary files,
|
|
|
|
|
and
|
|
|
|
|
POSIX-standard
|
|
|
|
|
.Dq ustar
|
|
|
|
|
archives.
|
|
|
|
|
The pax interchange format is a backwards-compatible tar format that
|
|
|
|
|
adds key/value attributes to each entry and supports arbitrary
|
|
|
|
|
filenames, linknames, uids, sizes, etc.
|
|
|
|
|
.Dq Restricted pax interchange format
|
|
|
|
|
is the library default; this is the same as pax format, but suppresses
|
|
|
|
|
the pax extended header for most normal files.
|
|
|
|
|
In most cases, this will result in ordinary ustar archives.
