- <STRONG>ncurses</STRONG> - CRT screen handling and optimization package
-
-
-</PRE>
-<H2>SYNOPSIS</H2><PRE>
- <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</STRONG>
-
-
-</PRE>
-<H2>DESCRIPTION</H2><PRE>
- The <STRONG>ncurses</STRONG> library routines give the user a terminal-
- independent method of updating character screens with rea-
- sonable optimization. This implementation is ``new
- curses'' (ncurses) and is the approved replacement for
- 4.4BSD classic curses, which has been discontinued. This
- describes <STRONG>ncurses</STRONG> version 5.9 (patch 20110404).
-
- The <STRONG>ncurses</STRONG> 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 <STRONG>ncurses</STRONG> library is
- freely redistributable in source form. Differences from
- the SVr4 curses are summarized under the <STRONG>EXTENSIONS</STRONG> and
- <STRONG>PORTABILITY</STRONG> sections below and described in detail in the
- respective <STRONG>EXTENSIONS</STRONG>, <STRONG>PORTABILITY</STRONG> and <STRONG>BUGS</STRONG> sections of
- individual man pages.
-
- The <STRONG>ncurses</STRONG> 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
- <STRONG>-lncurses</STRONG> option, or (if it has been generated) with the
- debugging library <STRONG>-lncurses_g</STRONG>. (Your system integrator
- may also have installed these libraries under the names
- <STRONG>-lcurses</STRONG> and <STRONG>-lcurses_g</STRONG>.) The ncurses_g library generates
- trace logs (in a file called 'trace' in the current direc-
- tory) that describe curses actions. See also the section
- on <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>.
-
- The <STRONG>ncurses</STRONG> package supports: overall screen, window and
- pad manipulation; output to windows and pads; reading ter-
- minal input; control over terminal and <STRONG>curses</STRONG> input and
- output options; environment query routines; color manipu-
- lation; use of soft label keys; terminfo capabilities; and
- access to low-level terminal-manipulation routines.
-
- The library uses the locale which the calling program has
- initialized. That is normally done with <STRONG>setlocale</STRONG>:
-
- <STRONG>setlocale(LC_ALL,</STRONG> <STRONG>"");</STRONG>
-
- 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 <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG> must be called to initial-
- ize the library before any of the other routines that deal
- with windows and screens are used. The routine <STRONG>endwin</STRONG>
- must be called before exiting.
-
- To get character-at-a-time input without echoing (most
- interactive, screen oriented programs want this), the fol-
- lowing sequence should be used:
-
- <STRONG>initscr();</STRONG> <STRONG>cbreak();</STRONG> <STRONG>noecho();</STRONG>
-
- Most programs would additionally use the sequence:
-
- <STRONG>nonl();</STRONG>
- <STRONG>intrflush(stdscr,</STRONG> <STRONG>FALSE);</STRONG>
- <STRONG>keypad(stdscr,</STRONG> <STRONG>TRUE);</STRONG>
-
- Before a <STRONG>curses</STRONG> program is run, the tab stops of the ter-
- minal should be set and its initialization strings, if
- defined, must be output. This can be done by executing
- the <STRONG>tput</STRONG> <STRONG>init</STRONG> command after the shell environment variable
- <STRONG>TERM</STRONG> has been exported. <STRONG>tset(1)</STRONG> is usually responsible
- for doing this. [See <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for further details.]
-
- The <STRONG>ncurses</STRONG> library permits manipulation of data struc-
- tures, called <EM>windows</EM>, which can be thought of as two-
- dimensional arrays of characters representing all or part
- of a CRT screen. A default window called <STRONG>stdscr</STRONG>, which is
- the size of the terminal screen, is supplied. Others may
- be created with <STRONG>newwin</STRONG>.
-
- Note that <STRONG>curses</STRONG> does not handle overlapping windows,
- that's done by the <STRONG><A HREF="panel.3x.html">panel(3x)</A></STRONG> library. This means that you
- can either use <STRONG>stdscr</STRONG> or divide the screen into tiled win-
- dows and not using <STRONG>stdscr</STRONG> at all. Mixing the two will
- result in unpredictable, and undesired, effects.
-
- Windows are referred to by variables declared as <STRONG>WINDOW</STRONG> <STRONG>*</STRONG>.
- These data structures are manipulated with routines
- described here and elsewhere in the <STRONG>ncurses</STRONG> manual pages.
- Among those, the most basic routines are <STRONG>move</STRONG> and <STRONG>addch</STRONG>.
- More general versions of these routines are included with
- names beginning with <STRONG>w</STRONG>, allowing the user to specify a
- window. The routines not beginning with <STRONG>w</STRONG> affect <STRONG>stdscr</STRONG>.
-
- After using routines to manipulate a window, <STRONG>refresh</STRONG> is
- called, telling <STRONG>curses</STRONG> to make the user's CRT screen look
- like <STRONG>stdscr</STRONG>. The characters in a window are actually of
- type <STRONG>chtype</STRONG>, (character and attribute data) so that other
- information about the character may also be stored with
- each character.
-
- Special windows called <EM>pads</EM> may also be manipulated.
- These are windows which are not constrained to the size of
- the screen and whose contents need not be completely dis-
- played. See <STRONG><A HREF="curs_pad.3x.html">curs_pad(3x)</A></STRONG> for more information.
-
- In addition to drawing characters on the screen, video
- attributes and colors may be supported, causing the char-
- acters 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, <STRONG>curses</STRONG> 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
- <STRONG>&lt;curses.h&gt;</STRONG>, such as <STRONG>A_REVERSE</STRONG>, <STRONG>ACS_HLINE</STRONG>, and <STRONG>KEY_LEFT</STRONG>.
-
- If the environment variables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> are set, or
- if the program is executing in a window environment, line
- and column information in the environment will override
- information read by <EM>terminfo</EM>. This would affect a program
- running in an AT&amp;T 630 layer, for example, where the size
- of a screen is changeable (see <STRONG>ENVIRONMENT</STRONG>).
-
- If the environment variable <STRONG>TERMINFO</STRONG> is defined, any pro-
- gram using <STRONG>curses</STRONG> checks for a local terminal definition
- before checking in the standard place. For example, if
- <STRONG>TERM</STRONG> is set to <STRONG>att4424</STRONG>, then the compiled terminal defini-
- tion is found in
-
- <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
-
- (The <STRONG>a</STRONG> is copied from the first letter of <STRONG>att4424</STRONG> to avoid
- creation of huge directories.) However, if <STRONG>TERMINFO</STRONG> is
- set to <STRONG>$HOME/myterms</STRONG>, <STRONG>curses</STRONG> first checks
-
- <STRONG>$HOME/myterms/a/att4424</STRONG>,
-
- and if that fails, it then checks
-
- <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
-
- This is useful for developing experimental definitions or
- when write permission in <STRONG>/usr/share/terminfo</STRONG> is not avail-
- able.
-
- The integer variables <STRONG>LINES</STRONG> and <STRONG>COLS</STRONG> are defined in
- <STRONG>&lt;curses.h&gt;</STRONG> and will be filled in by <STRONG>initscr</STRONG> with the size
- of the screen. The constants <STRONG>TRUE</STRONG> and <STRONG>FALSE</STRONG> have the val-
- ues <STRONG>1</STRONG> and <STRONG>0</STRONG>, respectively.
-
- The <STRONG>curses</STRONG> routines also define the <STRONG>WINDOW</STRONG> <STRONG>*</STRONG> variable
- <STRONG>curscr</STRONG> which is used for certain low-level operations like
- clearing and redrawing a screen containing garbage. The
- <STRONG>curscr</STRONG> can be used in only a few routines.
-
- <STRONG>Routine</STRONG> <STRONG>and</STRONG> <STRONG>Argument</STRONG> <STRONG>Names</STRONG>
- Many <STRONG>curses</STRONG> routines have two or more versions. The rou-
- tines prefixed with <STRONG>w</STRONG> require a window argument. The rou-
- tines prefixed with <STRONG>p</STRONG> require a pad argument. Those with-
- out a prefix generally use <STRONG>stdscr</STRONG>.
-
- The routines prefixed with <STRONG>mv</STRONG> require a <EM>y</EM> and <EM>x</EM> coordinate
- to move to before performing the appropriate action. The
- <STRONG>mv</STRONG> routines imply a call to <STRONG>move</STRONG> before the call to the
- other routine. The coordinate <EM>y</EM> always refers to the row
- (of the window), and <EM>x</EM> always refers to the column. The
- upper left-hand corner is always (0,0), not (1,1).
-
- The routines prefixed with <STRONG>mvw</STRONG> take both a window argument
- and <EM>x</EM> and <EM>y</EM> coordinates. The window argument is always
- specified before the coordinates.
-
- In each case, <EM>win</EM> is the window affected, and <EM>pad</EM> is the
- pad affected; <EM>win</EM> and <EM>pad</EM> are always pointers to type <STRONG>WIN-</STRONG>
- <STRONG>DOW</STRONG>.
-
- Option setting routines require a Boolean flag <EM>bf</EM> with the
- value <STRONG>TRUE</STRONG> or <STRONG>FALSE</STRONG>; <EM>bf</EM> is always of type <STRONG>bool</STRONG>. Most of
- the data types used in the library routines, such as <STRONG>WIN-</STRONG>
- <STRONG>DOW</STRONG>, <STRONG>SCREEN</STRONG>, <STRONG>bool</STRONG>, and <STRONG>chtype</STRONG> are defined in <STRONG>&lt;curses.h&gt;</STRONG>.
- Types used for the terminfo routines such as <STRONG>TERMINAL</STRONG> are
- defined in <STRONG>&lt;term.h&gt;</STRONG>.
-
- 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 <STRONG>chtype</STRONG>
- data.
-
- Attributes alone (no corresponding character)
- may be stored in <STRONG>chtype</STRONG> or the equivalent
- <STRONG>attr_t</STRONG> data. In either case, the data is
- stored in something like an integer.
-
- Each cell (row and column) in a <STRONG>WINDOW</STRONG> is
- stored as a <STRONG>chtype</STRONG>.
-
- ncursesw
- the so-called "wide" library, which handles
- multibyte characters (see the section on
- <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>). 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 charac-
- ters:
-
- <STRONG>cchar_t</STRONG>
- corresponds to <STRONG>chtype</STRONG>. However it is a
- structure, because more data is stored
- than can fit into an integer. The char-
- acters 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 sepa-
- rate fields of the structure.
-
- Each cell (row and column) in a <STRONG>WINDOW</STRONG> is
- stored as a <STRONG>cchar_t</STRONG>.
-
- <STRONG>wchar_t</STRONG>
- stores a "wide" character. Like <STRONG>chtype</STRONG>,
- this may be an integer.
-
- <STRONG>wint_t</STRONG>
- stores a <STRONG>wchar_t</STRONG> or <STRONG>WEOF</STRONG> - not the same,
- though both may have the same size.
-
- The "wide" library provides new functions
- which are analogous to functions in the "nor-
- mal" library. There is a naming convention
- which relates many of the normal/wide vari-
- ants: a "_w" is inserted into the name. For
- example, <STRONG>waddch</STRONG> becomes <STRONG>wadd_wch</STRONG>.
-
-
- <STRONG>Routine</STRONG> <STRONG>Name</STRONG> <STRONG>Index</STRONG>
- The following table lists each <STRONG>curses</STRONG> routine and the name
- of the manual page on which it is described. Routines
- flagged with `*' are ncurses-specific, not described by
- XPG4 or present in SVr4.

-<H2>RETURN VALUE</H2><PRE>
- Routines that return an integer return <STRONG>ERR</STRONG> upon failure
- and an integer value other than <STRONG>ERR</STRONG> upon successful com-
- pletion, unless otherwise noted in the routine descrip-
- tions.
-
- All macros return the value of the <STRONG>w</STRONG> version, except
- <STRONG>setscrreg</STRONG>, <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>, <STRONG>getbegyx</STRONG>, and <STRONG>getmaxyx</STRONG>. The
- return values of <STRONG>setscrreg</STRONG>, <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>, <STRONG>getbegyx</STRONG>,
- and <STRONG>getmaxyx</STRONG> are undefined (i.e., these should not be used
- as the right-hand side of assignment statements).
-
- Routines that return pointers return <STRONG>NULL</STRONG> on error.
-
-
-</PRE>
-<H2>ENVIRONMENT</H2><PRE>
- The following environment symbols are useful for customiz-
- ing the runtime behavior of the <STRONG>ncurses</STRONG> library. The most
- important ones have been already discussed in detail.
-
- BAUDRATE
- The debugging library checks this environment symbol
- when the application has redirected output to a file.
- The symbol's numeric value is used for the baudrate.
- If no value is found, <STRONG>ncurses</STRONG> uses 9600. This allows
- testers to construct repeatable test-cases that take
- into account costs that depend on baudrate.
-
- CC When set, change occurrences of the command_character
- (i.e., the <STRONG>cmdch</STRONG> capability) of the loaded terminfo
- entries to the value of this symbol. Very few ter-
- minfo entries provide this feature.
-
- Because this name is also used in development envi-
- ronments to represent the C compiler's name, <STRONG>ncurses</STRONG>
- ignores it if it does not happen to be a single char-
- acter.
-
- COLUMNS
- Specify the width of the screen in characters.
- Applications running in a windowing environment usu-
- ally are able to obtain the width of the window in
- which they are executing. If neither the <STRONG>COLUMNS</STRONG>
- value nor the terminal's screen size is available,
- <STRONG>ncurses</STRONG> uses the size which may be specified in the
- terminfo database (i.e., the <STRONG>cols</STRONG> capability).
-
- It is important that your application use a correct
- size for the screen. This is not always possible
- because your application may be running on a host
- which does not honor NAWS (Negotiations About Window
- Size), or because you are temporarily running as
- another user. However, setting <STRONG>COLUMNS</STRONG> and/or <STRONG>LINES</STRONG>
- overrides the library's use of the screen size
- obtained from the operating system.
-
- Either <STRONG>COLUMNS</STRONG> or <STRONG>LINES</STRONG> symbols may be specified
- independently. This is mainly useful to circumvent
- legacy misfeatures of terminal descriptions, e.g.,
- xterm which commonly specifies a 65 line screen. For
- best results, <STRONG>lines</STRONG> and <STRONG>cols</STRONG> should not be specified
- in a terminal description for terminals which are run
- as emulations.
-
- Use the <STRONG>use_env</STRONG> function to disable all use of exter-
- nal environment (including system calls) to determine
- the screen size.
-
- ESCDELAY
- Specifies the total time, in milliseconds, for which
- ncurses will await a character sequence, e.g., a
- function key. The default value, 1000 milliseconds,
- is enough for most uses. However, it is made a vari-
- able to accommodate unusual applications.
-
- The most common instance where you may wish to change
- this value is to work with slow hosts, e.g., running
- on a network. If the host cannot read characters
- rapidly enough, it will have the same effect as if
- the terminal did not send characters rapidly enough.
- The library will still see a timeout.
-
- Note that xterm mouse events are built up from char-
- acter sequences received from the xterm. If your
- application makes heavy use of multiple-clicking, you
- may wish to lengthen this default value because the
- timeout applies to the composed multi-click event as
- well as the individual clicks.
-
- In addition to the environment variable, this imple-
- mentation provides a global variable with the same
- name. Portable applications should not rely upon the
- presence of ESCDELAY in either form, but setting the
- environment variable rather than the global variable
- does not create problems when compiling an applica-
- tion.
-
- HOME Tells <STRONG>ncurses</STRONG> where your home directory is. That is
- where it may read and write auxiliary terminal
- descriptions:
-
- $HOME/.termcap
- $HOME/.terminfo
-
- LINES
- Like COLUMNS, specify the height of the screen in
- characters. See COLUMNS for a detailed description.
-
- MOUSE_BUTTONS_123
- This applies only to the OS/2 EMX port. It specifies
- the order of buttons on the mouse. OS/2 numbers a
- 3-button mouse inconsistently from other platforms:
-
- 1 = left
- 2 = right
- 3 = middle.
-
- This symbol lets you customize the mouse. The symbol
- must be three numeric digits 1-3 in any order, e.g.,
- 123 or 321. If it is not specified, <STRONG>ncurses</STRONG> uses
- 132.
-
- NCURSES_ASSUMED_COLORS
- Override the compiled-in assumption that the termi-
- nal's default colors are white-on-black (see
- <STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG>). You may set the foreground and
- background color values with this environment vari-
- able by proving a 2-element list: foreground,back-
- ground. For example, to tell ncurses to not assume
- anything about the colors, set this to "-1,-1". To
- make it green-on-black, set it to "2,0". Any posi-
- tive value from zero to the terminfo <STRONG>max_colors</STRONG> value
- is allowed.
-
- NCURSES_GPM_TERMS
- This applies only to ncurses configured to use the
- GPM interface.
-
- If present, the environment variable is a list of one
- or more terminal names against which the TERM envi-
- ronment variable is matched. Setting it to an empty
- value disables the GPM interface; using the built-in
- support for xterm, etc.
-
- If the environment variable is absent, ncurses will
- attempt to open GPM if TERM contains "linux".
-
- NCURSES_NO_HARD_TABS
- <STRONG>Ncurses</STRONG> may use tabs as part of the cursor movement
- optimization. In some cases, your terminal driver
- may not handle these properly. Set this environment
- variable to disable the feature. You can also adjust
- your <STRONG>stty</STRONG> settings to avoid the problem.
-
- NCURSES_NO_MAGIC_COOKIES
- Some terminals use a magic-cookie feature which
- requires special handling to make highlighting and
- other video attributes display properly. You can
- suppress the highlighting entirely for these termi-
- nals by setting this environment variable.
-
- NCURSES_NO_PADDING
- Most of the terminal descriptions in the terminfo
- database are written for real "hardware" terminals.
- Many people use terminal emulators which run in a
- windowing environment and use curses-based applica-
- tions. Terminal emulators can duplicate all of the
- important aspects of a hardware terminal, but they do
- not have the same limitations. The chief limitation
- of a hardware terminal from the standpoint of your
- application is the management of dataflow, i.e., tim-
- ing. Unless a hardware terminal is interfaced into a
- terminal concentrator (which does flow control), it
- (or your application) must manage dataflow, prevent-
- ing overruns. The cheapest solution (no hardware
- cost) is for your program to do this by pausing after
- operations that the terminal does slowly, such as
- clearing the display.
-
- As a result, many terminal descriptions (including
- the vt100) have delay times embedded. You may wish
- to use these descriptions, but not want to pay the
- performance penalty.
-
- Set the NCURSES_NO_PADDING symbol to disable all but
- mandatory padding. Mandatory padding is used as a
- part of special control sequences such as <EM>flash</EM>.
-
- NCURSES_NO_SETBUF
- Normally <STRONG>ncurses</STRONG> enables buffered output during ter-
- minal initialization. This is done (as in SVr4
- curses) for performance reasons. For testing pur-
- poses, both of <STRONG>ncurses</STRONG> and certain applications, this
- feature is made optional. Setting the
- NCURSES_NO_SETBUF variable disables output buffering,
- leaving the output in the original (usually line
- buffered) mode.
-
- NCURSES_NO_UTF8_ACS
- During initialization, the <STRONG>ncurses</STRONG> library checks for
- special cases where VT100 line-drawing (and the cor-
- responding alternate character set capabilities)
- described in the terminfo are known to be missing.
- Specifically, when running in a UTF-8 locale, the
- Linux console emulator and the GNU screen program
- ignore these. Ncurses checks the TERM environment
- variable for these. For other special cases, you
- should set this environment variable. Doing this
- tells ncurses to use Unicode values which correspond
- to the VT100 line-drawing glyphs. That works for the
- special cases cited, and is likely to work for termi-
- nal emulators.
-
- When setting this variable, you should set it to a
- nonzero value. Setting it to zero (or to a nonnum-
- ber) disables the special check for "linux" and
- "screen".
-
- As an alternative to the environment variable,
- ncurses checks for an extended terminfo capability
- <STRONG>U8</STRONG>. This is a numeric capability which can be com-
- piled using <STRONG>tic</STRONG> <STRONG>-x</STRONG>. For example
-
- # linux console, if patched to provide working
- # VT100 shift-in/shift-out, with corresponding font.
- linux-vt100|linux console with VT100 line-graphics,
- U8#0, use=linux,
-
- # uxterm with vt100Graphics resource set to false
- xterm-utf8|xterm relying on UTF-8 line-graphics,
- U8#1, use=xterm,
-
- The name "U8" is chosen to be two characters, to per-
- mit it to be used by applications that use ncurses'
- termcap interface.
-
- NCURSES_TRACE
- During initialization, the <STRONG>ncurses</STRONG> debugging library
- checks the NCURSES_TRACE symbol. If it is defined,
- to a numeric value, <STRONG>ncurses</STRONG> calls the <STRONG>trace</STRONG> function,
- using that value as the argument.
-
- The argument values, which are defined in <STRONG>curses.h</STRONG>,
- provide several types of information. When running
- with traces enabled, your application will write the
- file <STRONG>trace</STRONG> to the current directory.
-
- TERM Denotes your terminal type. Each terminal type is
- distinct, though many are similar.
-
- TERMCAP
- If the <STRONG>ncurses</STRONG> library has been configured with <EM>term-</EM>
- <EM>cap</EM> support, <STRONG>ncurses</STRONG> will check for a terminal's
- description in termcap form if it is not available in
- the terminfo database.
-
- The TERMCAP symbol contains either a terminal
- description (with newlines stripped out), or a file
- name telling where the information denoted by the
- TERM symbol exists. In either case, setting it
- directs <STRONG>ncurses</STRONG> to ignore the usual place for this
- information, e.g., /etc/termcap.
-
- TERMINFO
- Overrides the directory in which <STRONG>ncurses</STRONG> searches for
- your terminal description. This is the simplest, but
- not the only way to change the list of directories.
- The complete list of directories in order follows:
-
- <STRONG>o</STRONG> the last directory to which <STRONG>ncurses</STRONG> wrote, if
- any, is searched first
-
- <STRONG>o</STRONG> the directory specified by the TERMINFO symbol
-
- <STRONG>o</STRONG> $HOME/.terminfo
-
- <STRONG>o</STRONG> directories listed in the TERMINFO_DIRS symbol
-
- <STRONG>o</STRONG> one or more directories whose names are config-
- ured and compiled into the ncurses library, e.g.,
- /usr/share/terminfo
-
- TERMINFO_DIRS
- Specifies a list of directories to search for termi-
- nal descriptions. The list is separated by colons
- (i.e., ":") on Unix, semicolons on OS/2 EMX. All of
- the terminal descriptions are in terminfo form, which
- makes a subdirectory named for the first letter of
- the terminal names therein.
-
- TERMPATH
- If TERMCAP does not hold a file name then <STRONG>ncurses</STRONG>
- checks the TERMPATH symbol. This is a list of file-
- names separated by spaces or colons (i.e., ":") on
- Unix, semicolons on OS/2 EMX. If the TERMPATH symbol
- is not set, <STRONG>ncurses</STRONG> looks in the files /etc/termcap,
- /usr/share/misc/termcap and $HOME/.termcap, in that
- order.
-
- The library may be configured to disregard the following
- variables when the current user is the superuser (root),
- or if the application uses setuid or setgid permissions:
- $TERMINFO, $TERMINFO_DIRS, $TERMPATH, as well as $HOME.
-
-
-</PRE>
-<H2>ALTERNATE CONFIGURATIONS</H2><PRE>
- Several different configurations are possible, depending
- on the configure script options used when building
- <STRONG>ncurses</STRONG>. There are a few main options whose effects are
- visible to the applications developer using <STRONG>ncurses</STRONG>:
-
- --disable-overwrite
- The standard include for <STRONG>ncurses</STRONG> is as noted in <STRONG>SYN-</STRONG>
- <STRONG>OPSIS</STRONG>:
-
- <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</STRONG>
-
- This option is used to avoid filename conflicts when
- <STRONG>ncurses</STRONG> is not the main implementation of curses of
- the computer. If <STRONG>ncurses</STRONG> is installed disabling
- overwrite, it puts its headers in a subdirectory,
- e.g.,
-
- <STRONG>#include</STRONG> <STRONG>&lt;ncurses/curses.h&gt;</STRONG>
-
- It also omits a symbolic link which would allow you
- to use <STRONG>-lcurses</STRONG> to build executables.
-
- --enable-widec
- The configure script renames the library and (if the
- <STRONG>--disable-overwrite</STRONG> option is used) puts the header
- files in a different subdirectory. All of the
- library names have a "w" appended to them, i.e.,
- instead of
-
- <STRONG>-lncurses</STRONG>
-
- you link with
-
- <STRONG>-lncursesw</STRONG>
-
- You must also define <STRONG>_XOPEN_SOURCE_EXTENDED</STRONG> when com-
- piling for the wide-character library to use the
- extended (wide-character) functions. The <STRONG>curses.h</STRONG>
- file which is installed for the wide-character
- library is designed to be compatible with the normal
- library's header. Only the size of the <STRONG>WINDOW</STRONG> struc-
- ture differs, and very few applications require more
- than a pointer to <STRONG>WINDOW</STRONG>s. If the headers are
- installed allowing overwrite, the wide-character
- library's headers should be installed last, to allow
- applications to be built using either library from
- the same set of headers.
-
- --with-shared
-
- --with-normal
-
- --with-debug
-
- --with-profile
- The shared and normal (static) library names differ
- by their suffixes, e.g., <STRONG>libncurses.so</STRONG> and
- <STRONG>libncurses.a</STRONG>. The debug and profiling libraries add
- a "_g" and a "_p" to the root names respectively,
- e.g., <STRONG>libncurses_g.a</STRONG> and <STRONG>libncurses_p.a</STRONG>.
-
- --with-trace
- The <STRONG>trace</STRONG> function normally resides in the debug
- library, but it is sometimes useful to configure this
- in the shared library. Configure scripts should
- check for the function's existence rather than assum-
- ing it is always in the debug library.

-<H2>EXTENSIONS</H2><PRE>
- The <STRONG>ncurses</STRONG> library can be compiled with an option
- (<STRONG>-DUSE_GETCAP</STRONG>) that falls back to the old-style /etc/term-
- cap file if the terminal setup code cannot find a terminfo
- entry corresponding to <STRONG>TERM</STRONG>. Use of this feature is not
- recommended, as it essentially includes an entire termcap
- compiler in the <STRONG>ncurses</STRONG> startup code, at significant cost
- in core and startup cycles.
-
- The <STRONG>ncurses</STRONG> library includes facilities for capturing
- mouse events on certain terminals (including xterm). See
- the <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> manual page for details.
-
- The <STRONG>ncurses</STRONG> library includes facilities for responding to
- window resizing events, e.g., when running in an xterm.
- See the <STRONG><A HREF="resizeterm.3x.html">resizeterm(3x)</A></STRONG> and <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG> manual pages for
- details. In addition, the library may be configured with
- a SIGWINCH handler.
-
- The <STRONG>ncurses</STRONG> library extends the fixed set of function key
- capabilities of terminals by allowing the application
- designer to define additional key sequences at runtime.
- See the <STRONG><A HREF="define_key.3x.html">define_key(3x)</A></STRONG> <STRONG><A HREF="key_defined.3x.html">key_defined(3x)</A></STRONG>, and <STRONG><A HREF="keyok.3x.html">keyok(3x)</A></STRONG> man-
- ual pages for details.
-
- The <STRONG>ncurses</STRONG> library can exploit the capabilities of termi-
- nals which implement the ISO-6429 SGR 39 and SGR 49 con-
- trols, which allow an application to reset the terminal to
- its original foreground and background colors. From the
- users' perspective, the application is able to draw col-
- ored text on a background whose color is set indepen-
- dently, providing better control over color contrasts.
- See the <STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG> manual page for details.
-
- The <STRONG>ncurses</STRONG> library includes a function for directing
- application output to a printer attached to the terminal
- device. See the <STRONG><A HREF="curs_print.3x.html">curs_print(3x)</A></STRONG> manual page for details.

-<H2>PORTABILITY</H2><PRE>
- The <STRONG>ncurses</STRONG> library is intended to be BASE-level confor-
- mant with XSI Curses. The EXTENDED XSI Curses functional-
- ity (including color support) is supported.
-
- A small number of local differences (that is, individual
- differences between the XSI Curses and <STRONG>ncurses</STRONG> calls) are
- described in <STRONG>PORTABILITY</STRONG> sections of the library man
- pages.
-
- This implementation also contains several extensions:
-
- <STRONG>o</STRONG> The routine <STRONG>has_key</STRONG> is not part of XPG4, nor is it
- present in SVr4. See the <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG> manual page
- for details.
-
- <STRONG>o</STRONG> The routine <STRONG>slk_attr</STRONG> is not part of XPG4, nor is it
- present in SVr4. See the <STRONG><A HREF="curs_slk.3x.html">curs_slk(3x)</A></STRONG> manual page for
- details.
-
- <STRONG>o</STRONG> The routines <STRONG>getmouse</STRONG>, <STRONG>mousemask</STRONG>, <STRONG>ungetmouse</STRONG>, <STRONG>mousein-</STRONG>
- <STRONG>terval</STRONG>, and <STRONG>wenclose</STRONG> relating to mouse interfacing are
- not part of XPG4, nor are they present in SVr4. See
- the <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> manual page for details.
-
- <STRONG>o</STRONG> The routine <STRONG>mcprint</STRONG> was not present in any previous
- curses implementation. See the <STRONG><A HREF="curs_print.3x.html">curs_print(3x)</A></STRONG> manual
- page for details.
-
- <STRONG>o</STRONG> The routine <STRONG>wresize</STRONG> is not part of XPG4, nor is it
- present in SVr4. See the <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG> manual page for
- details.
-
- <STRONG>o</STRONG> The WINDOW structure's internal details can be hidden
- from application programs. See <STRONG><A HREF="curs_opaque.3x.html">curs_opaque(3x)</A></STRONG> for
- the discussion of <STRONG>is_scrollok</STRONG>, etc.
-
- <STRONG>o</STRONG> This implementation can be configured to provide rudi-
- mentary support for multi-threaded applications. See
- <STRONG><A HREF="curs_threads.3x.html">curs_threads(3x)</A></STRONG> for details.
-
- <STRONG>o</STRONG> This implementation can also be configured to provide
- a set of functions which improve the ability to manage
- multiple screens. See <STRONG><A HREF="curs_sp_funcs.3x.html">curs_sp_funcs(3x)</A></STRONG> for details.
-
- In historic curses versions, delays embedded in the capa-
- bilities <STRONG>cr</STRONG>, <STRONG>ind</STRONG>, <STRONG>cub1</STRONG>, <STRONG>ff</STRONG> and <STRONG>tab</STRONG> activated corresponding
- delay bits in the UNIX tty driver. In this implementa-
- tion, all padding is done by sending NUL bytes. This
- method is slightly more expensive, but narrows the inter-
- face to the UNIX kernel significantly and increases the
- package's portability correspondingly.

-<H2>NOTES</H2><PRE>
- The header file <STRONG>&lt;curses.h&gt;</STRONG> automatically includes the
- header files <STRONG>&lt;stdio.h&gt;</STRONG> and <STRONG>&lt;unctrl.h&gt;</STRONG>.
-
- If standard output from a <STRONG>ncurses</STRONG> program is re-directed
- to something which is not a tty, screen updates will be
- directed to standard error. This was an undocumented fea-
- ture of AT&amp;T System V Release 3 curses.
