ARCHIVE_READ_OPTIONS(3) FreeBSD Library Functions Manual
NAME archive_read_set_filter_option, archive_read_set_format_option, archive_read_set_option, archive_read_set_options - functions controlling options for reading archives
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. 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.
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.
ERRORS Detailed error codes and textual descriptions are available from the archive_errno() and archive_error_string() functions.
