LIBRARY

       Streaming Archive Library (libarchive, -larchive)

SYNOPSIS

       int
       archive_read_set_filter_option(struct archive *,         const char *module,          const char *option,
           const char *value);

       int
       archive_read_set_format_option(struct archive *,          const char *module,         const char *option,
           const char *value);

       int
       archive_read_set_option(struct archive *, const char *module, const char *option, const char *value);

       int
       archive_read_set_options(struct archive *, const char *options);

DESCRIPTION

       These functions provide a way for libarchive clients to configure specific read modules.

       archive_read_set_filter_option(), archive_read_set_format_option()
               Specifies an option that will be passed to currently-registered filters (including  decompression
               filters) or format readers.

               If  option  and  value  are  both  NULL,  these  functions will do nothing and ARCHIVE_OK will be
               returned.  If option is NULL but value is not, these functions will do nothing and ARCHIVE_FAILED
               will be returned.

               If module is not NULL, option and value will be provided to the filter or  reader  named  module.
               The  return value will be that of the module.  If there is no such module, ARCHIVE_FAILED will be
               returned.

               If module is NULL, option and value will be provided to every registered module.  If  any  module
               returns  ARCHIVE_FATAL,  this  value will be returned immediately.  Otherwise, ARCHIVE_OK will be
               returned if any module accepts the option, and ARCHIVE_FAILED in all other cases.

       archive_read_set_option()
               Calls  archive_read_set_format_option(),  then   archive_read_set_filter_option().    If   either
               function  returns  ARCHIVE_FATAL, ARCHIVE_FATAL will be returned immediately.  Otherwise, greater
               of the two values will be returned.

       archive_read_set_options()
               options is a comma-separated list of options.  If options is NULL or empty,  ARCHIVE_OK  will  be
               returned immediately.

               Calls  archive_read_set_option() with each option in turn.  If any archive_read_set_option() call
               returns ARCHIVE_FATAL, ARCHIVE_FATAL will be returned immediately.

               Individual options have one of the following forms:
               option=value
                       The option/value pair will be provided to every module.  Modules that do  not  accept  an
                       option with this name will ignore it.
               option  The option will be provided to every module with a value of “1”.
               !option
                       The option will be provided to every module with a NULL value.
               module:option=value, module:option, module:!option
                       As  above,  but the corresponding option and value will be provided only to modules whose
                       name matches module.

OPTIONS

       Format cab
               hdrcharset
                       The value is used as a character set name that will be used when translating file names.
       Format cpio
               compat-2x
                       Libarchive 2.x incorrectly encoded Unicode filenames  on  some  platforms.   This  option
                       mimics the libarchive 2.x filename handling so that such archives can be read correctly.
               hdrcharset
                       The value is used as a character set name that will be used when translating file names.
               pwb     When  reading  a  binary CPIO archive, assume that it is in the original PWB cpio format,
                       and handle file mode bits accordingly.  The default is to assume v7 format.
       Format iso9660
               joliet  Support Joliet extensions.  Defaults to enabled, use !joliet to disable.
               rockridge
                       Support RockRidge extensions.  Defaults to enabled, use !rockridge to disable.
       Format lha
               hdrcharset
                       The value is used as a character set name that will be used when translating file names.
       Format mtree
               checkfs
                       Allow reading information missing from the mtree  from  the  file  system.   Disabled  by
                       default.
       Format rar
               hdrcharset
                       The value is used as a character set name that will be used when translating file names.
       Format tar
               compat-2x
                       Libarchive  2.x  incorrectly  encoded  Unicode  filenames on some platforms.  This option
                       mimics the libarchive 2.x filename handling so that such archives can be read correctly.
               hdrcharset
                       The value is used as a character set name that will be used when translating file names.
               mac-ext
                       Support Mac OS metadata extension that records data in special  files  beginning  with  a
                       period  and underscore.  Defaults to enabled on Mac OS, disabled on other platforms.  Use
                       !mac-ext to disable.
               read_concatenated_archives
                       Ignore zeroed blocks in the archive, which occurs when multiple tar  archives  have  been
                       concatenated  together.  Without this option, only the contents of the first concatenated
                       archive would be read.
       Format zip
               compat-2x
                       Libarchive 2.x incorrectly encoded Unicode filenames  on  some  platforms.   This  option
                       mimics the libarchive 2.x filename handling so that such archives can be read correctly.
               hdrcharset
                       The value is used as a character set name that will be used when translating file names.
               ignorecrc32
                       Skip the CRC32 check.  Mostly used for testing.
               mac-ext
                       Support  Mac  OS  metadata  extension that records data in special files beginning with a
                       period and underscore.  Defaults to enabled on Mac OS, disabled on other platforms.   Use
                       !mac-ext to disable.
