 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">

     zip_uint8_t *data;    /* pointer to the actual data */

 </div>
 <p class="Pp">The data <var class="Ar">fragments</var> point to must remain
     valid for the lifetime of the created source.

 Upon successful completion, the created source is returned. Otherwise,

   <var class="Ar">archive</var> or <var class="Ar">error</var> is set to
   indicate the error.
