The functions <code class="Fn">zip_source_buffer_fragment</code>() and
<code class="Fn">zip_source_buffer_fragment_create</code>() create a zip
source from the data in <var class="Ar">fragments</var>.
<var class="Ar">nfragments</var> specifies the number of fragments. If
<var class="Ar">freep</var> is non-zero, the data will be freed when it is no
longer needed.
<div class="Bd Pp">
<pre>
struct zip_stat {
zip_uint8_t *data; /* pointer to the actual data */
zip_uint64_t length; /* length of this fragment */
};
</pre>
</div>
<p class="Pp">The data <var class="Ar">fragments</var> point to must remain
valid for the lifetime of the created source.
<var class="Ar">fragments</var> itself can be discarded once the source is
created.</p>
<p class="Pp">The source can be used to open a zip archive from.</p>

Upon successful completion, the created source is returned. Otherwise,
<code class="Dv">NULL</code> is returned and the error code in
<var class="Ar">archive</var> or <var class="Ar">error</var> is set to
indicate the error.
