DESCRIPTION

       archive_read_support_format_7zip(), archive_read_support_format_ar(),  archive_read_support_format_cab(),
               archive_read_support_format_cpio(),                        archive_read_support_format_iso9660(),
               archive_read_support_format_lha(),                           archive_read_support_format_mtree(),
               archive_read_support_format_rar(),                             archive_read_support_format_raw(),
               archive_read_support_format_tar(),                             archive_read_support_format_xar(),
               archive_read_support_format_zip()
               Enables support---including auto-detection code---for the specified archive format.  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.

RETURN VALUES

       These functions return ARCHIVE_OK on success, or ARCHIVE_FATAL.

ERRORS

       Detailed  error  codes  and  textual  descriptions   are   available   from   the   archive_errno()   and
       archive_error_string() functions.

BUGS

       Many traditional archiver programs treat  empty  files  as  valid  empty  archives.   For  example,  many
       implementations  of  tar(1) allow you to append entries to an empty file.  Of course, it is impossible to
       determine the format of an empty file by inspecting the contents, so this library treats empty  files  as
       having a special “empty” format.

       Using  the  “raw”  handler  together  with  any  other handler will often work but can produce surprising
       results.
