For example, \%archive_read_support_format_tar() enables support for a variety of standard tar formats, old-style tar, ustar, pax interchange format, and many common variants.
\%archive_read_support_format_all() Enables support for all available formats except the ``raw'' format (see below).
\%archive_read_support_format_by_code() Enables a single format specified by the format code. This can be useful when reading a single archive twice; use \%archive_format() after reading the first time and pass the resulting code to this function to selectively enable only the necessary format support. Note: In statically-linked executables, this will cause your program to include support for every format. If executable size is a concern, you may wish to avoid using this function.
\%archive_read_support_format_empty() Enables support for treating empty files as empty archives. Because empty files are valid for several different formats, it is not possible to accurately determine a format for an empty file based purely on contents. So empty files are treated by libarchive as a distinct format.
\%archive_read_support_format_raw() The ``raw'' format handler allows libarchive to be used to read arbitrary data. It treats any data stream as an archive with a single entry. The pathname of this entry is ``data ;'' all other entry fields are unset. This is not enabled by \%archive_read_support_format_all() in order to avoid erroneous handling of damaged archives.
Using the ``raw'' handler together with any other handler will often work but can produce surprising results.
