The function <code class="Fn" title="Fn">zip_source_read</code>() reads up to
<var class="Ar" title="Ar">len</var> bytes of data from
<var class="Ar" title="Ar">source</var> at the current read offset into the
buffer <var class="Ar" title="Ar">data</var>.
<div class="Pp"></div>
The zip source <var class="Ar" title="Ar">source</var> has to be opened for
reading by calling
<a class="Xr" title="Xr" href="zip_source_open.html">zip_source_open(3)</a>
first.
<h1 class="Sh" title="Sh" id="RETURN_VALUES"><a class="permalink" href="#RETURN_VALUES">RETURN
VALUES</a></h1>
Upon successful completion the number of bytes read is returned. Upon reading
end-of-file, zero is returned. Otherwise, -1 is returned and the error
information in <var class="Ar" title="Ar">source</var> is set to indicate the
error.
