.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.
The library can write a variety of common archive formats.
.Bl -tag -width indent
.It Fn archive_write_set_format
Sets the format based on the format code (see
.Pa archive.h
for the full list of format codes).
In particular, this can be used in conjunction with
.Fn archive_format
to create a new archive with the same format as an existing archive.
.It Fn archive_write_set_format_by_name
Sets the corresponding format based on the common name.
.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.
Sets both filters and format based on the output filename.
Supported extensions: .7z, .zip, .jar, .cpio, .iso, .a, .ar, .tar, .tgz, .tar.gz, .tar.bz2, .tar.xz
