  <para>
   <function>ftp_nb_fput</function> uploads the data from a file pointer to
   a remote file on the FTP server.
  </para>
  <para>
   The difference between this function and the <function>ftp_fput</function> 
   is that this function uploads the file asynchronously, so your program can
   perform other operations while the file is being uploaded.
