  <TD colspan="3"><P>Before your program terminates you need to free all resources you
  have allocated. If you checked the source on the previous page, you certainly
  spotted <CODE><A HREF="gloss.html#free">SQLFreeHandle</A></CODE>. This function must be used 
  to free each allocated handle. It expects a parameter which states the type of the handle
  to be freed and the handle itself. So if you want to free an environment handle you should 
  call (in our example program):</P>
  <CODE>
  SQLFreeHandle(SQL_HANDLE_ENV, V_OD_Env);
  </CODE>
  <P>
  Before you free any handle make sure that it is no longer needed, wouldn't be funny, if you
  released to connection handle but forgot to close the connection ;)</P>
  <P>
  And if you want to close a connection you need <CODE><A HREF="gloss.html#clos">SQLDisconnect</A></CODE>.
  This closes the connection associated with the connection handle offered as argument to <CODE>SQLDisconnect</CODE>.
  In our program we need to call:</P>
  <CODE>
  SQLDisconnect(V_OD_hdbc);
  </CODE>
  <P>
  If you need source code, please have a look <A HREF="conne.html#list">here</A>.</P>
