<p class="Pp">The
<a class="permalink" href="#zip_register_progress_callback_with_state"><code class="Fn" id="zip_register_progress_callback_with_state">zip_register_progress_callback_with_state</code></a>()
function registers a callback function <var class="Ar">callback</var> for
the zip archive <var class="Ar">archive</var>. The
<var class="Ar">precision</var> argument is a double in the range from 0.00
to 1.0 that defines the smallest change for which the callback should be
called (to avoid too frequent calls). The <var class="Ar">ud_free</var>
function is called during cleanup for deleting the userdata supplied in
<var class="Ar">ud</var>.</p>
<p class="Pp">The callback function is called during
<a class="Xr" href="zip_close.html">zip_close(3)</a> in regular intervals
(after every zip archive entry that's completely written to disk, and while
writing data for entries) with zip archive <var class="Ar">archive</var>,
the current progression state as a <var class="Vt">double</var>, and the
user-provided user-data <var class="Ar">ud</var> as arguments. The
progression state is a <var class="Vt">double</var> in the range from 0.0 to
1.0. This can be used to provide progress indicators for user
interfaces.</p>
