<p style="margin-left:6%;"><b>archive_read_set_filter_option</b>,
<b>archive_read_set_format_option</b>,
<b>archive_read_set_option</b>,
<b>archive_read_set_options</b> — functions
controlling options for reading archives</p>
<p style="margin-top: 1em"><b>LIBRARY</b></p>
<p style="margin-left:6%;">Streaming Archive Library
(libarchive, -larchive)</p>
<p style="margin-top: 1em"><b>SYNOPSIS</b></p>
<p style="margin-left:6%;"><i>int</i></p>
<p><b>archive_read_set_filter_option</b>(<i>struct archive *</i>,
<i>const char *module</i>,
<i>const char *option</i>,
<i>const char *value</i>);</p>

<p style="margin-left:6%; margin-top: 1em"><i>int</i></p>
<p><b>archive_read_set_options</b>(<i>struct archive *</i>,
<i>const char *options</i>);</p>
<p style="margin-top: 1em"><b>DESCRIPTION</b></p>
<p style="margin-left:6%;">These functions provide a way
for libarchive clients to configure specific read
modules.</p>
<p style="margin-top: 1em"><b>archive_read_set_filter_option</b>(),
<b>archive_read_set_format_option</b>()</p>
<p style="margin-left:17%;">Specifies an option that will
be passed to currently-registered filters (including
decompression filters) or format readers.</p>
<p style="margin-left:17%; margin-top: 1em">If
<i>option</i> and <i>value</i> are both NULL, these
functions will do nothing and <b>ARCHIVE_OK</b> will be
returned. If <i>option</i> is NULL but <i>value</i> is not,
these functions will do nothing and <b>ARCHIVE_FAILED</b>
will be returned.</p>
<p style="margin-left:17%; margin-top: 1em">If
<i>module</i> is not NULL, <i>option</i> and <i>value</i>
will be provided to the filter or reader named
<i>module</i>. The return value will be that of the module.
If there is no such module, <b>ARCHIVE_FAILED</b> will be
returned.</p>
<p style="margin-left:17%; margin-top: 1em">If
<i>module</i> is NULL, <i>option</i> and <i>value</i> will
be provided to every registered module. If any module
returns <b>ARCHIVE_FATAL</b>, this value will be returned
immediately. Otherwise, <b>ARCHIVE_OK</b> will be returned
if any module accepts the option, and <b>ARCHIVE_FAILED</b>
in all other cases.</p>
<p style="margin-top: 1em"><b>archive_read_set_option</b>()</p>
<p style="margin-left:17%;">Calls
<b>archive_read_set_format_option</b>(), then
<b>archive_read_set_filter_option</b>(). If either function
returns <b>ARCHIVE_FATAL</b>, <b>ARCHIVE_FATAL</b> will be
returned immediately. Otherwise, greater of the two values
will be returned.</p>
<p style="margin-top: 1em"><b>archive_read_set_options</b>()</p>
<p style="margin-left:17%;"><i>options</i> is a
comma-separated list of options. If <i>options</i> is NULL
or empty, <b>ARCHIVE_OK</b> will be returned
immediately.</p>
<p style="margin-left:17%; margin-top: 1em">Calls
<b>archive_read_set_option</b>() with each option in turn.
If any <b>archive_read_set_option</b>() call returns
<b>ARCHIVE_FATAL</b>, <b>ARCHIVE_FATAL</b> will be returned
immediately.</p>
<p style="margin-left:17%; margin-top: 1em">Individual
options have one of the following forms:</p>
<p><i>option=value</i></p>
<p style="margin-left:27%;">The option/value pair will be
provided to every module. Modules that do not accept an
option with this name will ignore it.</p>
<p><i>option</i></p>
<p style="margin-left:27%; margin-top: 1em">The option will
be provided to every module with a value of
’’1’’.</p>
<p><i>!option</i></p>
<p style="margin-left:27%;">The option will be provided to
every module with a NULL value.</p>
<p><i>module:option=value</i>, <i>module:option</i>,
<i>module:!option</i></p>
<p style="margin-left:27%;">As above, but the corresponding
option and value will be provided only to modules whose name
matches <i>module</i>.</p>
<p style="margin-top: 1em"><b>OPTIONS</b> <br>
Format iso9660 <b><br>
joliet</b></p>
<p style="margin-left:27%; margin-top: 1em">Support Joliet
extensions. Defaults to enabled, use <b>!joliet</b> to
disable.</p>
<p><b>rockridge</b></p>
<p style="margin-left:27%;">Support RockRidge extensions.
Defaults to enabled, use <b>!rockridge</b> to disable.</p>
<p>Format tar <b><br>
compat-2x</b></p>
<p style="margin-left:27%;">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.</p>
<p><b>hdrcharset</b></p>
<p style="margin-left:27%;">The value is used as a
character set name that will be used when translating
filenames.</p>
<p><b>mac-ext</b></p>
<p style="margin-left:27%;">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 <b>!mac-ext</b> to
disable.</p>
<p><b>read_concatenated_archives</b></p>
<p style="margin-left:27%;">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.</p>
<p style="margin-top: 1em"><b>ERRORS</b></p>
<p style="margin-left:6%;">Detailed error codes and textual
descriptions are available from the <b>archive_errno</b>()
and <b>archive_error_string</b>() functions.</p>
<p style="margin-top: 1em"><b>SEE ALSO</b></p>
