.Sh DESCRIPTION
These functions set the format that will be used for the archive.
.Pp
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.
.Bl -tag -width indent
.It Xo
.Fn archive_write_set_format_filter_by_ext ,
.Fn archive_write_set_format_filter_by_ext_def
.Xc
Format and filter for archive can be set automatically, based on output file name extension.
The functions are platform dependent.
Supported extensions: .7z, .zip, .jar, .cpio, .iso, .a, .ar, .tar, .tgz, .tar.gz, .tar.bz2, .tar.xz
