Most EXTENDED-level features not directlyconcerned with wide-character support are implemented, including manyfunction calls not supported under SVr4 curses (but portability of allcalls is documented so you can use the SVr4 subset only).<LI>Unlike SVr3 curses, ncurses can write to the rightmost-bottommost cornerof the screen if your terminal has an insert-character capability.<LI>Ada95 and C++ bindings.<LI>Support for mouse event reporting with X Window xterm and OS/2 console windows.<LI>Extended mouse support via Alessandro Rubini's gpm package.<LI>The function <CODE>wresize()</CODE> allows you to resize windows, preservingtheir data.<LI>The function <CODE>use_default_colors()</CODE> allows you touse the terminal's default colors for the default color pair,achieving the effect of transparent colors.<LI>The functions <CODE>keyok()</CODE>and <CODE>define_key()</CODE> allowyou to better control the use of function keys,e.g., disabling the ncurses KEY_MOUSE,or by defining more than one control sequence to map to a given key code.<LI>Support for 16-color terminals, such as aixterm and XFree86 xterm.<LI>Better cursor-movement optimization.  The package now features acursor-local-movement computation more efficient than either BSD'sor System V's.<LI>Super hardware scrolling support.  The screen-update code incorporatesa novel, simple, and cheap algorithm that enables it to make optimaluse of hardware scrolling, line-insertion, and line-deletionfor screen-line movements.  This algorithm is more powerful thanthe 4.4BSD curses quickch() routine.<LI>Real support for terminals with the magic-cookie glitch.  Thescreen-update code will refrain from drawing a highlight if the magic-cookie unattributed spaces required just before the beginning andafter the end would step on a non-space character.  It willautomatically shift highlight boundaries when doing so would make itpossible to draw the highlight without changing the visual appearanceof the screen.<LI>It is possible to generate the library with a list of pre-loadedfallback entries linked to it so that it can serve those terminal types evenwhen no terminfo tree or termcap file is accessible (this may be usefulfor support of screen-oriented programs that must run in single-user mode).<LI>The tic(1)/captoinfo utility provided with ncurses has theability to translate many termcaps from the XENIX, IBM andAT&amp;T extension sets.<LI>A BSD-like tset(1) utility is provided.<LI>The ncurses library and utilities will automatically read terminfoentries from $HOME/.terminfo if it exists, and compile to that directoryif it exists and the user has no write access to the system directory.This feature makes it easier for users to have personal terminfo entrieswithout giving up access to the system terminfo directory.<LI>You may specify a path of directories to search for compileddescriptions with the environment variable TERMINFO_DIRS (thisgeneralizes the feature provided by TERMINFO under stock System V.)<LI>In terminfo source files, use capabilities may refer not just toother entries in the same source file (as in System V) but also tocompiled entries in either the system terminfo directory or the user's$HOME/.terminfo directory.<LI>A script (<STRONG>capconvert</STRONG>) is provided to help BSD userstransition from termcap to terminfo.  It gathers the information in aTERMCAP environment variable and/or a ~/.termcap local entries fileand converts it to an equivalent local terminfo tree under $HOME/.terminfo.<LI>Automatic fallback to the /etc/termcap file can be compiled inwhen it is not possible to build a terminfo tree.  This feature is neitherfast nor cheap, you don't want to use it unless you have to,but it's there.<LI>The table-of-entries utility <STRONG>toe</STRONG> makes it easy for users tosee exactly what terminal types are available on the system.<LI>The library meets the XSI requirement that every macro entrypoint have a corresponding function which may be linked (and will beprototype-checked) if the macro definition is disabled with<CODE>#undef</CODE>.<LI>An HTML "Introduction to Programming with NCURSES" document providesa narrative introduction to the curses programming interface.</UL><H1>State of the Package</H1>Numerous bugs present in earlier versions have been fixed; thelibrary is far more reliable than it used to be.  Bounds checking in many`dangerous' entry points has been improved.  The code is now type-safeaccording to gcc -Wall.
