+ The "new curses" library offers the programmer a terminal-independent
+ means of reading keyboard and mouse input and updating character-cell
+ terminals with output optimized to minimize screen updates. <EM>ncurses</EM>
+ replaces the <EM>curses</EM> libraries from System V Release 4 Unix ("SVr4") and
+ 4.4BSD Unix, the development of which ceased in the 1990s. This
+ document describes <EM>ncurses</EM> version 6.4 (patch 20240420).
+
+ <EM>ncurses</EM> permits control of the terminal screen's contents; abstraction
+ and subdivision thereof with <EM>windows</EM> and <EM>pads</EM>; the reading of terminal
+ input; control of terminal input and output options; environment query
+ routines; color manipulation; the definition and use of <EM>soft</EM> <EM>label</EM>
+ keys; <EM>terminfo</EM> capability access; a <EM>termcap</EM> compatibility interface;
+ and an abstraction of the system's API for manipulating the terminal
+ (such as <STRONG>termios(3)</STRONG>).
+
+ <EM>ncurses</EM> implements the standard interface described by X/Open Curses
+ Issue 7. In many behavioral details not standardized by X/Open,
+ <EM>ncurses</EM> emulates the <EM>curses</EM> library of SVr4 and provides numerous
+ useful extensions.
+
+ <EM>ncurses</EM> man pages employ several sections to clarify matters of usage
+ and interoperability with other <EM>curses</EM> implementations.
+
+ <STRONG>o</STRONG> "NOTES" describes issues and caveats of which any user of the
+ <EM>ncurses</EM> API should be aware, such as limitations on the size of an
+ underlying integral type or the availability of a preprocessor
+ macro exclusive of a function definition (which prevents its
+ address from being taken). This section also describes
+ implementation details that will be significant to the programmer
+ but which are not standardized.
+
+ <STRONG>o</STRONG> "EXTENSIONS" presents <EM>ncurses</EM> innovations beyond the X/Open Curses
+ standard and/or the SVr4 <EM>curses</EM> implementation. They are termed
+ <EM>extensions</EM> to indicate that they cannot be implemented solely by
+ using the library API, but require access to the library's internal
+ state.
+
+ <STRONG>o</STRONG> "PORTABILITY" discusses matters (beyond the exercise of extensions)
+ that should be considered when writing to a <EM>curses</EM> standard, or for
+ multiple implementations.
+
+ <STRONG>o</STRONG> "HISTORY" examines points of detail in <EM>ncurses</EM> and other <EM>curses</EM>
+ implementations over the decades of their development, particularly
+ where precedent or inertia have frustrated better design (and, in a
+ few cases, where such inertia has been overcome).
+
+ A <EM>curses</EM> application must be linked with the library; use the <STRONG>-lncurses</STRONG>
+ option to your compiler or linker. A debugging version of the library
+ may be available; if so, link with it using <STRONG>-lncurses_g</STRONG>. (Your system
+ integrator may have installed these libraries such that you can use the
+ options <STRONG>-lcurses</STRONG> and <STRONG>-lcurses_g</STRONG>, respectively.) The <EM>ncurses</EM><STRONG>_</STRONG><EM>g</EM> library
+ generates trace logs (in a file called <EM>trace</EM> in the current directory)
+ that describe <EM>ncurses</EM> actions. See section "ALTERNATE CONFIGURATIONS"
+ below.
+
+
+</PRE><H3><a name="h3-Application-Structure">Application Structure</a></H3><PRE>
+ A <EM>curses</EM> application uses information from the system locale;
+ <STRONG>setlocale(3)</STRONG> prepares it for <EM>curses</EM> library calls.
+
+ setlocale(LC_ALL, "");
+
+ If the locale is not thus initialized, the library assumes that
+ characters are printable as in ISO 8859-1, to work with certain legacy
+ programs. You should initialize the locale; do not expect consistent
+ behavior from the library when the locale has not been set up.
+
+ <STRONG><A HREF="curs_initscr.3x.html">initscr(3x)</A></STRONG> or <STRONG><A HREF="curs_initscr.3x.html">newterm(3x)</A></STRONG> must be called to initialize <EM>curses</EM> before
+ use of any functions that deal with windows and screens.
+
+ To get character-at-a-time input without echoing--most interactive,
+ screen-oriented programs want this--use the following sequence.
+
+ initscr(); cbreak(); noecho();
+
+ Most applications perform further setup as follows.
+
+ intrflush(stdscr, FALSE);
+ keypad(stdscr, TRUE);
+
+ A <EM>curses</EM> program then often enters an event loop of some sort. Call
+ <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG> before exiting.
+
+
+</PRE><H3><a name="h3-Overview">Overview</a></H3><PRE>
+ A <EM>curses</EM> library abstracts the terminal screen by representing all or
+ part of it as a <EM>WINDOW</EM> data structure. A <EM>window</EM> is a rectangular grid
+ of character cells, addressed by row and column coordinates (<EM>y</EM>, <EM>x</EM>),
+ with the upper left corner as (0, 0). A window called <STRONG>stdscr</STRONG>, the same
+ size as the terminal screen, is always available. Create others with
+ <STRONG><A HREF="curs_window.3x.html">newwin(3x)</A></STRONG>.
+
+ A <EM>curses</EM> library does not manage overlapping windows (but see below).
+ You can either use <STRONG>stdscr</STRONG> to manage one screen-filling window, or tile
+ the screen into non-overlapping windows and not use <STRONG>stdscr</STRONG> at all.
+ Mixing the two approaches will result in unpredictable and undesired
+ effects.
+
+ Functions permit manipulation of a window and the <EM>cursor</EM> identifying
+ the cell within it at which the next output operation will occur.
+ Among those, the most basic are <STRONG><A HREF="curs_move.3x.html">move(3x)</A></STRONG> and <STRONG><A HREF="curs_addch.3x.html">addch(3x)</A></STRONG>: these place the
+ cursor and write a character to <STRONG>stdscr</STRONG>, respectively.
+
+ Frequent changes to the terminal screen can cause unpleasant flicker or
+ inefficient use of the communication channel to the device, so the
+ library does not generally update it automatically. Therefore, after
+ using <EM>curses</EM> functions to accumulate a set of desired updates that make
+ sense to present together, call <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG> to tell the library to make
+ the user's screen look like <STRONG>stdscr</STRONG>. The library <EM>optimizes</EM> its output
+ by computing a minimal number of operations to mutate the screen from
+ its state at the previous refresh to the new one. Effective
+ optimization demands accurate information about the terminal device:
+ the management of such information is the province of the <STRONG><A HREF="curs_terminfo.3x.html">terminfo(3x)</A></STRONG>
+ API, a feature of every standard <EM>curses</EM> implementation.
+
+ Special windows called <EM>pads</EM> may also be manipulated. These are windows
+ that are not constrained to the size of the terminal screen and whose
+ contents need not be completely displayed. See <STRONG><A HREF="curs_pad.3x.html">curs_pad(3x)</A></STRONG>.
+
+ In addition to drawing characters on the screen, rendering attributes
+ and colors may be supported, causing the characters to show up in such
+ modes as underlined, in reverse video, or in color on terminals that
+ support such display enhancements. See <STRONG><A HREF="curs_attr.3x.html">curs_attr(3x)</A></STRONG>.
+
+ <EM>curses</EM> predefines constants for a small set of forms-drawing graphics
+ corresponding to the DEC Alternate Character Set (ACS), a feature of
+ VT100 and other terminals. See <STRONG><A HREF="curs_addch.3x.html">waddch(3x)</A></STRONG>.
+
+ <EM>curses</EM> is implemented using the operating system's terminal driver;
+ keystroke events are received not as scan codes but as byte sequences.
+ Graphical keycaps (alphanumeric and punctuation keys, and the space)
+ appear as-is. Everything else, including the tab, enter/return,
+ keypad, arrow, and function keys, appears as a control character or a
+ multibyte <EM>escape</EM> <EM>sequence.</EM> <EM>curses</EM> translates these into unique <EM>key</EM>
+ <EM>codes.</EM> See <STRONG><A HREF="curs_getch.3x.html">getch(3x)</A></STRONG>.
+
+ <EM>ncurses</EM> provides reimplementations of the SVr4 <STRONG><A HREF="panel.3x.html">panel(3x)</A></STRONG>, <STRONG><A HREF="form.3x.html">form(3x)</A></STRONG>, and
+ <STRONG><A HREF="menu.3x.html">menu(3x)</A></STRONG> libraries to ease construction of user interfaces with <EM>curses</EM>.
+
+
+</PRE><H3><a name="h3-Initialization">Initialization</a></H3><PRE>
+ The selection of an appropriate value of <EM>TERM</EM> in the process
+ environment is essential to correct <EM>curses</EM> and <EM>terminfo</EM> library
+ operation. A well-configured system selects a correct <EM>TERM</EM> value
+ automatically; <STRONG><A HREF="tset.1.html">tset(1)</A></STRONG> may assist with troubleshooting exotic
+ situations.
+
+ If you change the terminal type, export the <EM>TERM</EM> environment variable
+ in the shell, then run <STRONG><A HREF="tset.1.html">tset(1)</A></STRONG> or the "<STRONG>tput</STRONG> <STRONG>init</STRONG>" command. See
+ subsection "Tabs and Initialization" of <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.
+
+ If the environment variables <EM>LINES</EM> and <EM>COLUMNS</EM> are set, or if the
+ <EM>curses</EM> program is executing in a graphical windowing environment, the
+ information obtained thence overrides that obtained by <EM>terminfo</EM>. An
+ <EM>ncurses</EM> extension supports resizable terminals; see <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG>.
+
+ If the environment variable <EM>TERMINFO</EM> is defined, a <EM>curses</EM> program
+ checks first for a terminal type description in the location it
+ identifies. <EM>TERMINFO</EM> is useful for developing experimental type
+ descriptions or when write permission to <EM>/usr/share/terminfo</EM> is not
+ available.
+
+ See section "ENVIRONMENT" below.
+
+
+</PRE><H3><a name="h3-Naming-Conventions">Naming Conventions</a></H3><PRE>
+ <EM>curses</EM> offers many functions in variant forms using a regular set of
+ alternatives to the name of an elemental one. Those prefixed with "w"
+ require a <EM>WINDOW</EM> pointer argument; those with a "mv" prefix first
+ perform cursor movement using <STRONG><A HREF="curs_move.3x.html">wmove(3x)</A></STRONG>; a "mvw" prefix indicates both.
+ The "w" function is typically the elemental one; the removal of this
+ prefix usually indicates operation on <STRONG>stdscr</STRONG>.
+
+ Four functions prefixed with "p" require a pad argument.
+
+ In function synopses, <EM>ncurses</EM> man pages apply the following names to
+ parameters.
+
+ <EM>bf</EM> <EM>bool</EM> (<STRONG>TRUE</STRONG> or <STRONG>FALSE</STRONG>)

+
+</PRE><H3><a name="h3-Wide-and-Non-wide-Character-Configurations">Wide and Non-wide Character Configurations</a></H3><PRE>
+ This manual page describes functions that appear in any configuration
+ of the library. There are two common configurations; see section
+ "ALTERNATE CONFIGURATIONS" below.
+
+ <EM>ncurses</EM> is the library in its "non-wide" configuration, handling only
+ eight-bit characters. It stores a character combined with
+ attributes in a <EM>chtype</EM> datum, which is often an alias of <EM>int</EM>.
+
+ Attributes alone (with no corresponding character) can be
+ stored in variables of <EM>chtype</EM> or <EM>attr</EM><STRONG>_</STRONG><EM>t</EM> type. In either
+ case, they are represented as an integral bit mask.
+
+ Each cell of a <EM>WINDOW</EM> is stored as a <EM>chtype</EM>.
+
+ <EM>ncursesw</EM> is the library in its "wide" configuration, which handles
+ character encodings requiring a larger data type than <EM>char</EM> (a
+ byte-sized type) can represent. It adds about one third more
+ calls using additional data types that can store such
+ <EM>multibyte</EM> characters.
+
+ <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM> corresponds to the non-wide configuration's <EM>chtype</EM>.
+ It always a structure type, because it stores more
+ data than fit into a standard scalar type. A
+ character code may not be representable as a <EM>char</EM>,
+ and moreover more than one character may occupy a
+ cell (as with accent marks and other diacritics).
+ Each character is of type <EM>wchar</EM><STRONG>_</STRONG><EM>t</EM>; a complex
+ character contains one spacing character and zero or
+ more non-spacing characters (see below). Attributes
+ and color data are stored in separate fields of the
+ structure, not combined as in <EM>chtype</EM>.
+
+ Each cell of a <EM>WINDOW</EM> is stored as a <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>.
+
+ <STRONG><A HREF="curs_getcchar.3x.html">setcchar(3x)</A></STRONG> and <STRONG><A HREF="curs_getcchar.3x.html">getcchar(3x)</A></STRONG> store and retrieve <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>
+ data. The wide library API of <EM>ncurses</EM> depends on two data
+ types standardized by ISO C95.
+
+ <EM>wchar</EM><STRONG>_</STRONG><EM>t</EM> stores a wide character. Like <EM>chtype</EM>, it may be an
+ alias of <EM>int</EM>. Depending on the character encoding,
+ a wide character may be <EM>spacing</EM>, meaning that it
+ occupies a character cell by itself and typically
+ accompanies cursor advancement, or <EM>non-spacing</EM>,
+ meaning that it occupies the same cell as a spacing
+ character, is often regarded as a "modifier" of the
+ base glyph with which it combines, and typically
+ does not advance the cursor.
+
+ <EM>wint</EM><STRONG>_</STRONG><EM>t</EM> can store a <EM>wchar</EM><STRONG>_</STRONG><EM>t</EM> or the constant <STRONG>WEOF</STRONG>,
+ analogously to the <EM>int</EM>-sized character manipulation
+ functions of ISO C and its constant <STRONG>EOF</STRONG>.
+
+ The wide library provides additional functions that
+ complement those in the non-wide library where the size of
+ the underlying character type is significant. A somewhat
+ regular naming convention relates many of the wide variants
+ to their non-wide counterparts; where a non-wide function
+ name contains "ch" or "str", prefix it with "_w" to obtain
+ the wide counterpart. For example, <STRONG>waddch</STRONG> becomes <STRONG>wadd_wch</STRONG>.
+ (Exceptions that add only "w" comprise <STRONG>addwstr</STRONG>, <STRONG>inwstr</STRONG>, and
+ their variants.)
+
+ This convention is inapplicable to some non-wide function
+ names, so other transformations are used for the wide
+ configuration: the window background management function
+ "bkgd" becomes "bkgrnd"; the window border-drawing and
+ -clearing functions are suffixed with "_set"; and character
+ attribute manipulation functions like "attron" become
+ "attr_on".

+ capability of the terminal type's entry in the <EM>terminfo</EM> database, if
+ any.
+
+ It is important that your application use the correct screen size.
+ Automatic detection thereof is not always possible because an
+ application may be running on a host that does not honor NAWS
+ (Negotiations About Window Size) or as a different user ID than the
+ owner of the terminal device file. Setting <EM>COLUMNS</EM> and/or <EM>LINES</EM>
+ overrides the library's use of the screen size obtained from the

+
+ The <EM>COLUMNS</EM> and <EM>LINES</EM> variables may be specified independently. This

+ descriptions; <STRONG>xterm(1)</STRONG> descriptions specifying 65 lines were once

+ For <EM>curses</EM> to distinguish the ESC character resulting from a user's
+ press of the "Escape" key on the input device from one beginning an
+ <EM>escape</EM> <EM>sequence</EM> (as commonly produced by function keys), it waits after
+ receiving the escape character to see if further characters are
+ available on the input stream within a short interval. A global
+ variable <STRONG>ESCDELAY</STRONG> stores this interval in milliseconds. The default
+ value of 1000 (one second) is adequate for most uses. This environment
+ variable overrides it.
+
+ The most common instance where you may wish to change this value is to
+ work with a remote host over a slow communication channel. If the host
+ running a <EM>curses</EM> application does not receive the characters of an
+ escape sequence in a timely manner, the library can interpret them as
+ multiple key stroke events.
+
+ <STRONG>xterm(1)</STRONG> mouse events are a form of escape sequence; therefore, if your
+ application makes heavy use of multiple-clicking, you may wish to
+ lengthen the default value because the delay applies to the composite
+ multi-click event as well as the individual clicks.
+
+ Portable applications should not rely upon the presence of <STRONG>ESCDELAY</STRONG> in
+ either form, but setting the environment variable rather than the
+ global variable does not create problems when compiling an application.
+

+
+ For example, to tell <EM>ncurses</EM> not to assume anything about the colors,

+ Most terminal type descriptions in the <EM>terminfo</EM> database detail

+ programs can duplicate all of the important features of a hardware
+ terminal, but often lack their limitations. Chief among these absent
+ drawbacks is the problem of data flow management; that is, limiting the
+ speed of communication to what the hardware could handle. Unless a
+ hardware terminal is interfaced into a terminal concentrator (which
+ does flow control), an application must manage flow control itself to
+ prevent overruns and data loss.
+
+ A solution that comes at no hardware cost is for an application to
+ pause after directing a terminal to execute an operation that it
+ performs slowly, such as clearing the display. Many terminal type
+ descriptions, including that for the VT100, embed delay specifications
+ in capabilities. You may wish to use these temrinal descriptions
+ without paying the performance penalty. Set <EM>NCURSES</EM><STRONG>_</STRONG><EM>NO</EM><STRONG>_</STRONG><EM>PADDING</EM> to any

+</PRE><H3><a name="h3-NCURSES_NO_SETBUF"><EM>NCURSES_NO_SETBUF</EM></a></H3><PRE>
+ (Obsolete) Prior to internal changes developed in <EM>ncurses</EM> 5.9 (patches
+ 20120825 through 20130126), the library used <STRONG>setbuf(3)</STRONG> to enable fully
+ buffered output when initializing the terminal. This was done, as in
+ SVr4 <EM>curses</EM>, to increase performance. For testing purposes, both of
+ <EM>ncurses</EM> and of certain applications, this feature was made optional.
+ Setting this variable disabled output buffering, leaving the output
+ stream in the original (usually line-buffered) mode.
+
+ Nowadays, <EM>ncurses</EM> performs its own buffering and does not require this
+ workaround; it does not modify the buffering of the standard output
+ stream. This approach makes signal handling, as for interrupts, more
+ robust. A drawback is that certain unconventional programs mixed
+ <STRONG>stdio(3)</STRONG> calls with <EM>ncurses</EM> calls and (usually) got the behavior they
+ expected. This is no longer the case; <EM>ncurses</EM> does not write to the
+ standard output file descriptor through a <EM>stdio</EM>-buffered stream.
+
+ As a special case, low-level API calls such as <STRONG><A HREF="curs_terminfo.3x.html">putp(3x)</A></STRONG> still use the
+ standard output stream. High-level <EM>curses</EM> calls such as <STRONG><A HREF="curs_printw.3x.html">printw(3x)</A></STRONG> do
+ not.

+ At initialization, <EM>ncurses</EM> inspects the <EM>TERM</EM> environment variable for
+ special cases where VT100 forms-drawing characters (and the
+ corresponding alternate character set <EM>terminfo</EM> capabilities) are known
+ to be unsupported by terminal types that otherwise claim VT100
+ compatibility. Specifically, when running in a UTF-8 locale, the Linux
+ virtual console device and the GNU <STRONG>screen(1)</STRONG> program ignore them. Set
+ this variable to a nonzero value to instruct <EM>ncurses</EM> that the
+ terminal's ACS support is broken; the library then outputs Unicode code
+ points that correspond to the forms-drawing characters. Set it to zero
+ (or a non-integer) to disable the special check for terminal type names
+ matching "linux" or "screen", directing <EM>ncurses</EM> to assume that the ACS
+ feature works if the terminal type description advertises it.
+
+ As an alternative to use of this variable, <EM>ncurses</EM> checks for an
+ extended <EM>terminfo</EM> numeric capability <STRONG>U8</STRONG> that can be compiled using "<STRONG>tic</STRONG>
+ <STRONG>-x</STRONG>". Examples follow.
