+ These functions are extensions to the curses library which do not fit
+ easily into other categories.
- Use <EM>curses</EM><STRONG>_</STRONG><EM>version()</EM> to get the version number, including
- patch level of the library, e.g., <STRONG>5.0.19991023</STRONG>
- The <EM>use</EM><STRONG>_</STRONG><EM>extended</EM><STRONG>_</STRONG><EM>names()</EM> function controls whether the
- calling application is able to use user-defined or non-
- standard names which may be compiled 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.

-<H2>PORTABILITY</H2><PRE>
- These routines are specific to ncurses. They were not

- It is recommended that any code depending on them be con-
- ditioned using NCURSES_VERSION.
