+ In any implementation of X/Open Curses, an application can free part of
+ the memory allocated by curses:
+
+ <STRONG>o</STRONG> The portable part of <STRONG>exit_curses</STRONG> can be freed using <STRONG>delscreen</STRONG>,
+ passing the <STRONG>SCREEN*</STRONG> pointer returned by <STRONG>newterm</STRONG>.
+
+ In some implementations, there is a global variable <STRONG>sp</STRONG> which could
+ be used, e.g., if the screen were only initialized using <STRONG>initscr</STRONG>.
+
+ <STRONG>o</STRONG> The portable part of <STRONG>exit_terminfo</STRONG> can be freed using <STRONG>del_curterm</STRONG>.
+
+ In this case, there is a global variable <STRONG>cur_term</STRONG> which can be used
+ as parameter.
