1mDESCRIPTION0m
       1marchive_read_support_format_7zip22m(),	  1marchive_read_support_format_ar22m(),
	       1marchive_read_support_format_cab22m(),
	       1marchive_read_support_format_cpio22m(),
	       1marchive_read_support_format_iso966022m(),
	       1marchive_read_support_format_lha22m(),
	       1marchive_read_support_format_mtree22m(),
	       1marchive_read_support_format_rar22m(),
	       1marchive_read_support_format_rar522m(),
	       1marchive_read_support_format_raw22m(),
	       1marchive_read_support_format_tar22m(),
	       1marchive_read_support_format_warc22m(),
	       1marchive_read_support_format_xar22m(),
	       1marchive_read_support_format_zip22m()
	       Enables support---including auto-detection code---for the spec‐
	       ified	    archive	   format.	   For	      example,
	       1marchive_read_support_format_tar22m() enables support for a variety
	       of  standard tar formats, old-style tar, ustar, pax interchange
	       format,	      and	 many	      common	     variants.
	       1marchive_read_support_format_zip22m()  enables support for both the
	       streaming and the seeking zip readers, which can separately  be
	       enabled			   by			  respectively
	       1marchive_read_support_format_zip_streamable22m()		and
	       1marchive_read_support_format_zip_seekable22m()
       1marchive_read_support_format_all22m()
	       Enables support for all available formats except the “raw” for‐
	       mat (see below).
       1marchive_read_support_format_by_code22m()
	       Enables a single format specified by the format code.  This can
	       be   useful   when   reading   a	  single  archive  twice;  use
	       1marchive_format22m() after reading the first time and pass the	re‐
	       sulting	code  to  this function to selectively enable only the
	       necessary format support.  Note:	 In statically-linked executa‐
	       bles, 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.
       1marchive_read_support_format_empty22m()
	       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.
       1marchive_read_support_format_raw22m()
	       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
	       1marchive_read_support_format_all22m() in order to  avoid  erroneous
	       handling of damaged archives.

1mRETURN VALUES0m
       These functions return 1mARCHIVE_OK 22mon success, or 1mARCHIVE_FATAL22m.

1mERRORS0m
       Detailed	 error	codes  and textual descriptions are available from the
       1marchive_errno22m() and 1marchive_error_string22m() functions.

1mBUGS0m
       Many  traditional  archiver  programs  treat empty files as valid empty
       archives.  For example, many implementations of 4mtar24m(1) allow you to ap‐
       pend entries to an empty file.  Of course, it is impossible  to	deter‐
       mine  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.
