    <simpara>
     This function returns header or meta data from files opened with
     <function>fopen</function>.  This is useful to return the response
     headers for HTTP connections, or some other statistics for other
     resources.
    </simpara>
    <simpara>
     The format of the returned data is deliberately undocumented at this
     time, and depends on which wrapper(s) were used to open the file.
