The function <code class="Fn">zip_source_read</code>() reads up to
<var class="Ar">len</var> bytes of data from <var class="Ar">source</var> at
the current read offset into the buffer <var class="Ar">data</var>.
<p class="Pp">The zip source <var class="Ar">source</var> has to be opened for
reading by calling
