<h1 class="Sh" id="DESCRIPTION"><a class="permalink" href="#DESCRIPTION">DESCRIPTION</a></h1>
<code class="Nm">libzip</code> is a library for reading, creating, and modifying
zip archives.
<p class="Pp">The main design criteria for <code class="Nm">libzip</code>
were:</p>
<ul class="Bl-bullet Bl-compact">
<li>Do not create corrupt files, even in case of errors.</li>
<li>Do not delete data.</li>
<li>Be efficient.</li>
</ul>
<p class="Pp">For this reason, when modifying zip archives,
<code class="Nm">libzip</code> writes to a temporary file and replaces the
original zip archive atomically.</p>
<p class="Pp">Below there are two sections listing functions: one for how to
read from zip archives and one for how to create/modify them.</p>
</section>
<section class="Sh">
<h1 class="Sh" id="GENERAL_NOTES"><a class="permalink" href="#GENERAL_NOTES">GENERAL
NOTES</a></h1>
Unless explicitly documented, functions should not be passed
<code class="Dv">NULL</code> pointers as arguments.
</section>
<section class="Sh">
<h1 class="Sh" id="FILE_NAMES"><a class="permalink" href="#FILE_NAMES">FILE
NAMES</a></h1>
<section class="Ss">
<h2 class="Ss" id="Encoding"><a class="permalink" href="#Encoding">Encoding</a></h2>
Names of files in the host file system are expected in UTF-8 encoding. On
Windows, variants for ASCII and UTF-16 are also available.
<p class="Pp">Names of files inside archives are by default expected in UTF-8
encoding. Other encodings can be requested by using the flags
<code class="Dv">ZIP_FL_ENC_CP437</code> and
<code class="Dv">ZIP_FL_ENC_RAW</code>.</p>
<p class="Pp">For details see the relevant man pages.</p>
</section>
<section class="Ss">
<h2 class="Ss" id="Directory_Separator"><a class="permalink" href="#Directory_Separator">Directory
Separator</a></h2>
The zip format requires the use of forward slash (‘/’) as
directory separator. Since backslash (‘\’) can be part of a
valid file name on Unix systems, <code class="Nm">libzip</code> does not
automatically convert them, even on Windows. It is the responsibility of the
programmer to ensure that all directory separators are passed as forward
slashes to <code class="Nm">libzip</code>.
</section>
</section>
<section class="Sh">
<h1 class="Sh" id="THREAD_SAFETY"><a class="permalink" href="#THREAD_SAFETY">THREAD
SAFETY</a></h1>
In general, different zip archives opened by <code class="Nm">libzip</code> are
independent of each other and can be used by parallel-running threads without
locking. If you want to use an archive from multiple threads, you have to
synchronize access to it yourself. If you use an archive as a source for
<a class="Xr" href="zip_file_add.html">zip_file_add(3)</a> or
<a class="Xr" href="zip_file_replace.html">zip_file_replace(3)</a>, access to
the target archive must be synchronized with access to the source archive as
well.
