+ The <STRONG>use_extended_names</STRONG> function controls whether the calling applica-
+ tion is able to use user-defined or nonstandard names which may be com-
+ piled into the terminfo description, i.e., via the terminfo or termcap
+ interfaces. Normally these names are available for use, since the
+ essential decision is made by using the <STRONG>-x</STRONG> option of <STRONG>tic</STRONG> to compile
+ extended terminal definitions. However you can disable this feature to
+ ensure compatibility with other implementations of curses.
