The ncurses library routines give the user a terminal-independent
method of updating character screens with reasonable
optimization. This implementation is 'new curses' (ncurses) and
is the approved replacement for 4.4BSD classic curses, which has
been discontinued. This describes ncurses version
@NCURSES_MAJOR@.@NCURSES_MINOR@ (patch @NCURSES_PATCH@).
The ncurses library emulates the curses library of System V
Release 4 UNIX, and XPG4 (X/Open Portability Guide) curses (also
known as XSI curses). XSI stands for X/Open System Interfaces
Extension. The ncurses library is freely redistributable in
source form. Differences from the SVr4 curses are summarized
under the EXTENSIONS and PORTABILITY sections below and described
in detail in the respective EXTENSIONS, PORTABILITY and BUGS
sections of individual man pages.
The ncurses library also provides many useful extensions, i.e.,
features which cannot be implemented by a simple add-on library
but which require access to the internals of the library.
A program using these routines must be linked with the -lncurses
option, or (if it has been generated) with the debugging library
-lncurses_g. (Your system integrator may also have installed
these libraries under the names -lcurses and -lcurses_g.) The
ncurses_g library generates trace logs (in a file called 'trace'
in the current directory) that describe curses actions. See also
the section on ALTERNATE CONFIGURATIONS.
The ncurses package supports: overall screen, window and pad
manipulation; output to windows and pads; reading terminal input;
control over terminal and curses input and output options;
environment query routines; color manipulation; use of soft label
keys; terminfo capabilities; and access to low-level terminal-
manipulation routines.
Initialization
The library uses the locale which the calling program has
initialized. That is normally done with setlocale:
setlocale(LC_ALL, "");
If the locale is not initialized, the library assumes that
characters are printable as in ISO-8859-1, to work with certain
legacy programs. You should initialize the locale and not rely
on specific details of the library when the locale has not been
setup.
The function initscr or newterm must be called to initialize the
library before any of the other routines that deal with windows
and screens are used. The routine endwin(3X) must be called
before exiting.
To get character-at-a-time input without echoing (most
interactive, screen oriented programs want this), the following
sequence should be used:
initscr(); cbreak(); noecho();
Most programs would additionally use the sequence:
intrflush(stdscr, FALSE);
keypad(stdscr, TRUE);
Before a curses program is run, the tab stops of the terminal
should be set and its initialization strings, if defined, must be
output. This can be done by executing the @TPUT@ init command
after the shell environment variable TERM has been exported.
@TSET@(1) is usually responsible for doing this. [See
terminfo(5) for further details.]
Datatypes
The ncurses library permits manipulation of data structures,
called windows, which can be thought of as two-dimensional arrays
of characters representing all or part of a CRT screen. A
default window called stdscr, which is the size of the terminal
screen, is supplied. Others may be created with newwin.
Note that curses does not handle overlapping windows, that's done
by the panel(3X) library. This means that you can either use
stdscr or divide the screen into tiled windows and not using
stdscr at all. Mixing the two will result in unpredictable, and
undesired, effects.
Windows are referred to by variables declared as WINDOW *. These
data structures are manipulated with routines described here and
elsewhere in the ncurses manual pages. Among those, the most
basic routines are move and addch. More general versions of
these routines are included with names beginning with w, allowing
the user to specify a window. The routines not beginning with w
affect stdscr.
After using routines to manipulate a window, refresh(3X) is
called, telling curses to make the user's CRT screen look like
stdscr. The characters in a window are actually of type chtype,
(character and attribute data) so that other information about
the character may also be stored with each character.
Special windows called pads may also be manipulated. These are
windows which are not constrained to the size of the screen and
whose contents need not be completely displayed. See
curs_pad(3X) for more information.
In addition to drawing characters on the screen, video 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. Line drawing
characters may be specified to be output. On input, curses is
also able to translate arrow and function keys that transmit
escape sequences into single values. The video attributes, line
drawing characters, and input values use names, defined in
<curses.h>, such as A_REVERSE, ACS_HLINE, and KEY_LEFT.
Environment variables
If the environment variables LINES and COLUMNS are set, or if the
program is executing in a window environment, line and column
information in the environment will override information read by
terminfo. This would affect a program running in an AT&T 630
layer, for example, where the size of a screen is changeable (see
ENVIRONMENT).
If the environment variable TERMINFO is defined, any program
using curses checks for a local terminal definition before
checking in the standard place. For example, if TERM is set to
att4424, then the compiled terminal definition is found in
@TERMINFO@/a/att4424.
(The a is copied from the first letter of att4424 to avoid
creation of huge directories.) However, if TERMINFO is set to
$HOME/myterms, curses first checks
$HOME/myterms/a/att4424,
and if that fails, it then checks
@TERMINFO@/a/att4424.
This is useful for developing experimental definitions or when
write permission in @TERMINFO@ is not available.
The integer variables LINES and COLS are defined in <curses.h>
and will be filled in by initscr with the size of the screen.
The constants TRUE and FALSE have the values 1 and 0,
respectively.
The curses routines also define the WINDOW * variable curscr
which is used for certain low-level operations like clearing and
redrawing a screen containing garbage. The curscr can be used in
only a few routines.
Routine and Argument Names
Many curses routines have two or more versions. The routines
prefixed with w require a window argument. The routines prefixed
with p require a pad argument. Those without a prefix generally
use stdscr.
The routines prefixed with mv require a y and x coordinate to
move to before performing the appropriate action. The mv
routines imply a call to move before the call to the other
routine. The coordinate y always refers to the row (of the
window), and x always refers to the column. The upper left-hand
corner is always (0,0), not (1,1).
The routines prefixed with mvw take both a window argument and x
and y coordinates. The window argument is always specified
before the coordinates.
In each case, win is the window affected, and pad is the pad
affected; win and pad are always pointers to type WINDOW.
Option setting routines require a Boolean flag bf with the value
TRUE or FALSE; bf is always of type bool. Most of the data types
used in the library routines, such as WINDOW, SCREEN, bool, and
chtype are defined in <curses.h>. Types used for the terminfo
routines such as TERMINAL are defined in <term.h>.
This manual page describes functions which may appear in any
configuration of the library. There are two common
configurations of the library:
ncurses
the 'normal' library, which handles 8-bit characters.
The normal (8-bit) library stores characters combined
with attributes in chtype data.
Attributes alone (no corresponding character) may be
stored in chtype or the equivalent attr_t data. In
either case, the data is stored in something like an
integer.
Each cell (row and column) in a WINDOW is stored as a
chtype.
ncursesw
the so-called 'wide' library, which handles multibyte
characters (see the section on ALTERNATE CONFIGURATIONS).
The 'wide' library includes all of the calls from the
'normal' library. It adds about one third more calls
using data types which store multibyte characters:
cchar_t
corresponds to chtype. However it is a structure,
because more data is stored than can fit into an
integer. The characters are large enough to require
a full integer value - and there may be more than
one character per cell. The video attributes and
color are stored in separate fields of the
structure.
Each cell (row and column) in a WINDOW is stored as
a cchar_t.
The setcchar(3X) and getcchar(3X) functions store
and retrieve the data from a cchar_t structure.
wchar_t
stores a 'wide' character. Like chtype, this may be
an integer.
wint_t
stores a wchar_t or WEOF - not the same, though both
may have the same size.
The 'wide' library provides new functions which are
analogous to functions in the 'normal' library. There is
a naming convention which relates many of the normal/wide
variants: a '_w' is inserted into the name. For example,
waddch becomes wadd_wch.
Routine Name Index
The following table lists the curses routines provided in the
'normal' and 'wide' libraries and the names of the manual pages
on which they are described. Routines flagged with '*' are
ncurses-specific, not described by XPG4 or present in SVr4.
