58 The <STRONG>ncurses</STRONG> library routines give the user a terminal-independent
59 method of updating character screens with reasonable optimization.
60 This implementation is "new curses" (ncurses) and is the approved
61 replacement for 4.4BSD classic curses, which has been discontinued.
62 This describes <STRONG>ncurses</STRONG> version 6.1 (patch 20190921).
64 The <STRONG>ncurses</STRONG> library emulates the curses library of System V Release 4
65 UNIX, and XPG4 (X/Open Portability Guide) curses (also known as XSI
66 curses). XSI stands for X/Open System Interfaces Extension. The
67 <STRONG>ncurses</STRONG> library is freely redistributable in source form. Differences
68 from the SVr4 curses are summarized under the <STRONG>EXTENSIONS</STRONG> and <STRONG>PORTABIL-</STRONG>
69 <STRONG>ITY</STRONG> sections below and described in detail in the respective <STRONG>EXTEN-</STRONG>
70 <STRONG>SIONS</STRONG>, <STRONG>PORTABILITY</STRONG> and <STRONG>BUGS</STRONG> sections of individual man pages.
72 The <STRONG>ncurses</STRONG> library also provides many useful extensions, i.e., fea-
73 tures which cannot be implemented by a simple add-on library but which
74 require access to the internals of the library.
76 A program using these routines must be linked with the <STRONG>-lncurses</STRONG>
77 option, or (if it has been generated) with the debugging library
78 <STRONG>-lncurses_g</STRONG>. (Your system integrator may also have installed these
79 libraries under the names <STRONG>-lcurses</STRONG> and <STRONG>-lcurses_g</STRONG>.) The ncurses_g
80 library generates trace logs (in a file called 'trace' in the current
81 directory) that describe curses actions. See also the section on
82 <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>.
84 The <STRONG>ncurses</STRONG> package supports: overall screen, window and pad manipula-
85 tion; output to windows and pads; reading terminal input; control over
86 terminal and <STRONG>curses</STRONG> input and output options; environment query rou-
87 tines; color manipulation; use of soft label keys; terminfo capabili-
88 ties; and access to low-level terminal-manipulation routines.
91 </PRE><H3><a name="h3-Initialization">Initialization</a></H3><PRE>
92 The library uses the locale which the calling program has initialized.
93 That is normally done with <STRONG>setlocale</STRONG>:
95 <STRONG>setlocale(LC_ALL,</STRONG> <STRONG>"");</STRONG>
97 If the locale is not initialized, the library assumes that characters
98 are printable as in ISO-8859-1, to work with certain legacy programs.
99 You should initialize the locale and not rely on specific details of
100 the library when the locale has not been setup.
102 The function <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG> must be called to initialize the
103 library before any of the other routines that deal with windows and
104 screens are used. The routine <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG> must be called before exit-
107 To get character-at-a-time input without echoing (most interactive,
108 screen oriented programs want this), the following sequence should be
111 <STRONG>initscr();</STRONG> <STRONG>cbreak();</STRONG> <STRONG>noecho();</STRONG>
113 Most programs would additionally use the sequence:
115 <STRONG>nonl();</STRONG>
116 <STRONG>intrflush(stdscr,</STRONG> <STRONG>FALSE);</STRONG>
117 <STRONG>keypad(stdscr,</STRONG> <STRONG>TRUE);</STRONG>
119 Before a <STRONG>curses</STRONG> program is run, the tab stops of the terminal should be
120 set and its initialization strings, if defined, must be output. This
121 can be done by executing the <STRONG>tput</STRONG> <STRONG>init</STRONG> command after the shell environ-
122 ment variable <STRONG>TERM</STRONG> has been exported. <STRONG>tset(1)</STRONG> is usually responsible
123 for doing this. [See <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for further details.]
126 </PRE><H3><a name="h3-Datatypes">Datatypes</a></H3><PRE>
127 The <STRONG>ncurses</STRONG> library permits manipulation of data structures, called
128 <EM>windows</EM>, which can be thought of as two-dimensional arrays of charac-
129 ters representing all or part of a CRT screen. A default window called
130 <STRONG>stdscr</STRONG>, which is the size of the terminal screen, is supplied. Others
131 may be created with <STRONG>newwin</STRONG>.
133 Note that <STRONG>curses</STRONG> does not handle overlapping windows, that's done by
134 the <STRONG><A HREF="panel.3x.html">panel(3x)</A></STRONG> library. This means that you can either use <STRONG>stdscr</STRONG> or
135 divide the screen into tiled windows and not using <STRONG>stdscr</STRONG> at all. Mix-
136 ing the two will result in unpredictable, and undesired, effects.
138 Windows are referred to by variables declared as <STRONG>WINDOW</STRONG> <STRONG>*</STRONG>. These data
139 structures are manipulated with routines described here and elsewhere
140 in the <STRONG>ncurses</STRONG> manual pages. Among those, the most basic routines are
141 <STRONG>move</STRONG> and <STRONG>addch</STRONG>. More general versions of these routines are included
142 with names beginning with <STRONG>w</STRONG>, allowing the user to specify a window.
143 The routines not beginning with <STRONG>w</STRONG> affect <STRONG>stdscr</STRONG>.
145 After using routines to manipulate a window, <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG> is called,
146 telling <STRONG>curses</STRONG> to make the user's CRT screen look like <STRONG>stdscr</STRONG>. The
147 characters in a window are actually of type <STRONG>chtype</STRONG>, (character and
148 attribute data) so that other information about the character may also
149 be stored with each character.
151 Special windows called <EM>pads</EM> may also be manipulated. These are windows
152 which are not constrained to the size of the screen and whose contents
153 need not be completely displayed. See <STRONG><A HREF="curs_pad.3x.html">curs_pad(3x)</A></STRONG> for more informa-
156 In addition to drawing characters on the screen, video attributes and
157 colors may be supported, causing the characters to show up in such
158 modes as underlined, in reverse video, or in color on terminals that
159 support such display enhancements. Line drawing characters may be
160 specified to be output. On input, <STRONG>curses</STRONG> is also able to translate
161 arrow and function keys that transmit escape sequences into single val-
162 ues. The video attributes, line drawing characters, and input values
163 use names, defined in <STRONG><curses.h></STRONG>, such as <STRONG>A_REVERSE</STRONG>, <STRONG>ACS_HLINE</STRONG>, and
164 <STRONG>KEY_LEFT</STRONG>.
167 </PRE><H3><a name="h3-Environment-variables">Environment variables</a></H3><PRE>
168 If the environment variables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> are set, or if the pro-
169 gram is executing in a window environment, line and column information
170 in the environment will override information read by <EM>terminfo</EM>. This
171 would affect a program running in an AT&T 630 layer, for example, where
172 the size of a screen is changeable (see <STRONG>ENVIRONMENT</STRONG>).
174 If the environment variable <STRONG>TERMINFO</STRONG> is defined, any program using
175 <STRONG>curses</STRONG> checks for a local terminal definition before checking in the
176 standard place. For example, if <STRONG>TERM</STRONG> is set to <STRONG>att4424</STRONG>, then the com-
177 piled terminal definition is found in
179 <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
181 (The <STRONG>a</STRONG> is copied from the first letter of <STRONG>att4424</STRONG> to avoid creation of
182 huge directories.) However, if <STRONG>TERMINFO</STRONG> is set to <STRONG>$HOME/myterms</STRONG>,
183 <STRONG>curses</STRONG> first checks
185 <STRONG>$HOME/myterms/a/att4424</STRONG>,
187 and if that fails, it then checks
189 <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
191 This is useful for developing experimental definitions or when write
192 permission in <STRONG>/usr/share/terminfo</STRONG> is not available.
194 The integer variables <STRONG>LINES</STRONG> and <STRONG>COLS</STRONG> are defined in <STRONG><curses.h></STRONG> and will
195 be filled in by <STRONG>initscr</STRONG> with the size of the screen. The constants
196 <STRONG>TRUE</STRONG> and <STRONG>FALSE</STRONG> have the values <STRONG>1</STRONG> and <STRONG>0</STRONG>, respectively.
198 The <STRONG>curses</STRONG> routines also define the <STRONG>WINDOW</STRONG> <STRONG>*</STRONG> variable <STRONG>curscr</STRONG> which is
199 used for certain low-level operations like clearing and redrawing a
200 screen containing garbage. The <STRONG>curscr</STRONG> can be used in only a few rou-
204 </PRE><H3><a name="h3-Routine-and-Argument-Names">Routine and Argument Names</a></H3><PRE>
205 Many <STRONG>curses</STRONG> routines have two or more versions. The routines prefixed
206 with <STRONG>w</STRONG> require a window argument. The routines prefixed with <STRONG>p</STRONG> require
207 a pad argument. Those without a prefix generally use <STRONG>stdscr</STRONG>.
209 The routines prefixed with <STRONG>mv</STRONG> require a <EM>y</EM> and <EM>x</EM> coordinate to move to
210 before performing the appropriate action. The <STRONG>mv</STRONG> routines imply a call
211 to <STRONG>move</STRONG> before the call to the other routine. The coordinate <EM>y</EM> always
212 refers to the row (of the window), and <EM>x</EM> always refers to the column.
213 The upper left-hand corner is always (0,0), not (1,1).
215 The routines prefixed with <STRONG>mvw</STRONG> take both a window argument and <EM>x</EM> and <EM>y</EM>
216 coordinates. The window argument is always specified before the coor-
219 In each case, <EM>win</EM> is the window affected, and <EM>pad</EM> is the pad affected;
220 <EM>win</EM> and <EM>pad</EM> are always pointers to type <STRONG>WINDOW</STRONG>.
222 Option setting routines require a Boolean flag <EM>bf</EM> with the value <STRONG>TRUE</STRONG>
223 or <STRONG>FALSE</STRONG>; <EM>bf</EM> is always of type <STRONG>bool</STRONG>. Most of the data types used in
224 the library routines, such as <STRONG>WINDOW</STRONG>, <STRONG>SCREEN</STRONG>, <STRONG>bool</STRONG>, and <STRONG>chtype</STRONG> are
225 defined in <STRONG><curses.h></STRONG>. Types used for the terminfo routines such as
226 <STRONG>TERMINAL</STRONG> are defined in <STRONG><term.h></STRONG>.
228 This manual page describes functions which may appear in any configura-
229 tion of the library. There are two common configurations of the
233 the "normal" library, which handles 8-bit characters. The nor-
234 mal (8-bit) library stores characters combined with attributes
235 in <STRONG>chtype</STRONG> data.
237 Attributes alone (no corresponding character) may be stored in
238 <STRONG>chtype</STRONG> or the equivalent <STRONG>attr_t</STRONG> data. In either case, the data
239 is stored in something like an integer.
241 Each cell (row and column) in a <STRONG>WINDOW</STRONG> is stored as a <STRONG>chtype</STRONG>.
244 the so-called "wide" library, which handles multibyte charac-
245 ters (see the section on <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>). The "wide"
246 library includes all of the calls from the "normal" library.
247 It adds about one third more calls using data types which store
248 multibyte characters:
250 <STRONG>cchar_t</STRONG>
251 corresponds to <STRONG>chtype</STRONG>. However it is a structure, because
252 more data is stored than can fit into an integer. The
253 characters are large enough to require a full integer
254 value - and there may be more than one character per cell.
255 The video attributes and color are stored in separate
256 fields of the structure.
258 Each cell (row and column) in a <STRONG>WINDOW</STRONG> is stored as a
259 <STRONG>cchar_t</STRONG>.
261 <STRONG>wchar_t</STRONG>
262 stores a "wide" character. Like <STRONG>chtype</STRONG>, this may be an
265 <STRONG>wint_t</STRONG>
266 stores a <STRONG>wchar_t</STRONG> or <STRONG>WEOF</STRONG> - not the same, though both may
269 The "wide" library provides new functions which are analogous
270 to functions in the "normal" library. There is a naming con-
271 vention which relates many of the normal/wide variants: a "_w"
272 is inserted into the name. For example, <STRONG>waddch</STRONG> becomes
273 <STRONG>wadd_wch</STRONG>.

743 Routines that return an integer return <STRONG>ERR</STRONG> upon failure and an integer
744 value other than <STRONG>ERR</STRONG> upon successful completion, unless otherwise noted
745 in the routine descriptions.
747 As a general rule, routines check for null pointers passed as parame-
748 ters, and handle this as an error.
750 All macros return the value of the <STRONG>w</STRONG> version, except <STRONG>setscrreg</STRONG>,
751 <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>, <STRONG>getbegyx</STRONG>, and <STRONG>getmaxyx</STRONG>. The return values of

756 Routines that return pointers return <STRONG>NULL</STRONG> on error.
759 </PRE><H2><a name="h2-ENVIRONMENT">ENVIRONMENT</a></H2><PRE>
760 The following environment symbols are useful for customizing the run-
761 time behavior of the <STRONG>ncurses</STRONG> library. The most important ones have
762 been already discussed in detail.
765 </PRE><H3><a name="h3-CC-command-character">CC command-character</a></H3><PRE>
766 When set, change occurrences of the command_character (i.e., the <STRONG>cmdch</STRONG>
767 capability) of the loaded terminfo entries to the value of this vari-
768 able. Very few terminfo entries provide this feature.
770 Because this name is also used in development environments to represent
771 the C compiler's name, <STRONG>ncurses</STRONG> ignores it if it does not happen to be a
775 </PRE><H3><a name="h3-BAUDRATE">BAUDRATE</a></H3><PRE>
776 The debugging library checks this environment variable when the appli-
777 cation has redirected output to a file. The variable's numeric value
778 is used for the baudrate. If no value is found, <STRONG>ncurses</STRONG> uses 9600.
779 This allows testers to construct repeatable test-cases that take into
780 account costs that depend on baudrate.
783 </PRE><H3><a name="h3-COLUMNS">COLUMNS</a></H3><PRE>
784 Specify the width of the screen in characters. Applications running in
785 a windowing environment usually are able to obtain the width of the
786 window in which they are executing. If neither the <STRONG>COLUMNS</STRONG> value nor
787 the terminal's screen size is available, <STRONG>ncurses</STRONG> uses the size which
788 may be specified in the terminfo database (i.e., the <STRONG>cols</STRONG> capability).
790 It is important that your application use a correct size for the
791 screen. This is not always possible because your application may be
792 running on a host which does not honor NAWS (Negotiations About Window
793 Size), or because you are temporarily running as another user. How-
794 ever, setting <STRONG>COLUMNS</STRONG> and/or <STRONG>LINES</STRONG> overrides the library's use of the
795 screen size obtained from the operating system.
797 Either <STRONG>COLUMNS</STRONG> or <STRONG>LINES</STRONG> symbols may be specified independently. This
798 is mainly useful to circumvent legacy misfeatures of terminal descrip-
799 tions, e.g., xterm which commonly specifies a 65 line screen. For best
800 results, <STRONG>lines</STRONG> and <STRONG>cols</STRONG> should not be specified in a terminal descrip-
801 tion for terminals which are run as emulations.
803 Use the <STRONG>use_env</STRONG> function to disable all use of external environment
804 (but not including system calls) to determine the screen size. Use the
805 <STRONG>use_tioctl</STRONG> function to update <STRONG>COLUMNS</STRONG> or <STRONG>LINES</STRONG> to match the screen size
806 obtained from system calls or the terminal database.

810 Specifies the total time, in milliseconds, for which ncurses will await
811 a character sequence, e.g., a function key. The default value, 1000
812 milliseconds, is enough for most uses. However, it is made a variable
813 to accommodate unusual applications.
815 The most common instance where you may wish to change this value is to
816 work with slow hosts, e.g., running on a network. If the host cannot
817 read characters rapidly enough, it will have the same effect as if the
818 terminal did not send characters rapidly enough. The library will
821 Note that xterm mouse events are built up from character sequences
822 received from the xterm. If your application makes heavy use of multi-
823 ple-clicking, you may wish to lengthen this default value because the
824 timeout applies to the composed multi-click event as well as the indi-
827 In addition to the environment variable, this implementation provides a
828 global variable with the same name. Portable applications should not
829 rely upon the presence of ESCDELAY in either form, but setting the
830 environment variable rather than the global variable does not create
831 problems when compiling an application.

856 This variable lets you customize the mouse. The variable must be three
857 numeric digits 1-3 in any order, e.g., 123 or 321. If it is not speci-

862 Override the compiled-in assumption that the terminal's default colors
863 are white-on-black (see <STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG>). You may set the fore-
864 ground and background color values with this environment variable by
865 proving a 2-element list: foreground,background. For example, to tell
866 ncurses to not assume anything about the colors, set this to "-1,-1".
867 To make it green-on-black, set it to "2,0". Any positive value from
868 zero to the terminfo <STRONG>max_colors</STRONG> value is allowed.

874 The <STRONG>Console2</STRONG> program's handling of the Microsoft Console API call <STRONG>Cre-</STRONG>

909 Most of the terminal descriptions in the terminfo database are written
910 for real "hardware" terminals. Many people use terminal emulators
911 which run in a windowing environment and use curses-based applications.
912 Terminal emulators can duplicate all of the important aspects of a
913 hardware terminal, but they do not have the same limitations. The
914 chief limitation of a hardware terminal from the standpoint of your
915 application is the management of dataflow, i.e., timing. Unless a
916 hardware terminal is interfaced into a terminal concentrator (which
917 does flow control), it (or your application) must manage dataflow, pre-
918 venting overruns. The cheapest solution (no hardware cost) is for your
919 program to do this by pausing after operations that the terminal does
920 slowly, such as clearing the display.
922 As a result, many terminal descriptions (including the vt100) have
923 delay times embedded. You may wish to use these descriptions, but not
924 want to pay the performance penalty.
926 Set the NCURSES_NO_PADDING environment variable to disable all but
927 mandatory padding. Mandatory padding is used as a part of special con-
928 trol sequences such as <EM>flash</EM>.

932 This setting is obsolete. Before changes

936 <STRONG>o</STRONG> continued though 5.9 patch 20130126
938 <STRONG>ncurses</STRONG> enabled buffered output during terminal initialization. This
939 was done (as in SVr4 curses) for performance reasons. For testing pur-
940 poses, both of <STRONG>ncurses</STRONG> and certain applications, this feature was made
941 optional. Setting the NCURSES_NO_SETBUF variable disabled output
942 buffering, leaving the output in the original (usually line buffered)
945 In the current implementation, ncurses performs its own buffering and
946 does not require this workaround. It does not modify the buffering of
949 The reason for the change was to make the behavior for interrupts and
950 other signals more robust. One drawback is that certain nonconven-
951 tional programs would mix ordinary stdio calls with ncurses calls and
952 (usually) work. This is no longer possible since ncurses is not using
953 the buffered standard output but its own output (to the same file
954 descriptor). As a special case, the low-level calls such as <STRONG>putp</STRONG> still
955 use the standard output. But high-level curses calls do not.

959 During initialization, the <STRONG>ncurses</STRONG> library checks for special cases
960 where VT100 line-drawing (and the corresponding alternate character set
961 capabilities) described in the terminfo are known to be missing.
962 Specifically, when running in a UTF-8 locale, the Linux console emula-
963 tor and the GNU screen program ignore these. Ncurses checks the <STRONG>TERM</STRONG>
964 environment variable for these. For other special cases, you should
965 set this environment variable. Doing this tells ncurses to use Unicode
966 values which correspond to the VT100 line-drawing glyphs. That works
967 for the special cases cited, and is likely to work for terminal emula-
970 When setting this variable, you should set it to a nonzero value. Set-
971 ting it to zero (or to a nonnumber) disables the special check for
972 "linux" and "screen".
974 As an alternative to the environment variable, ncurses checks for an
975 extended terminfo capability <STRONG>U8</STRONG>. This is a numeric capability which
976 can be compiled using <STRONG>tic</STRONG> <STRONG>-x</STRONG>. For example
978 # linux console, if patched to provide working
979 # VT100 shift-in/shift-out, with corresponding font.
980 linux-vt100|linux console with VT100 line-graphics,
983 # uxterm with vt100Graphics resource set to false
984 xterm-utf8|xterm relying on UTF-8 line-graphics,
987 The name "U8" is chosen to be two characters, to permit it to be used
988 by applications that use ncurses' termcap interface.
991 </PRE><H3><a name="h3-NCURSES_TRACE">NCURSES_TRACE</a></H3><PRE>
992 During initialization, the <STRONG>ncurses</STRONG> debugging library checks the
993 NCURSES_TRACE environment variable. If it is defined, to a numeric
994 value, <STRONG>ncurses</STRONG> calls the <STRONG>trace</STRONG> function, using that value as the argu-
997 The argument values, which are defined in <STRONG>curses.h</STRONG>, provide several
998 types of information. When running with traces enabled, your applica-
999 tion will write the file <STRONG>trace</STRONG> to the current directory.

1005 Denotes your terminal type. Each terminal type is distinct, though
1008 <STRONG>TERM</STRONG> is commonly set by terminal emulators to help applications find a
1009 workable terminal description. Some of those choose a popular approxi-
1010 mation, e.g., "ansi", "vt100", "xterm" rather than an exact fit. Not
1011 infrequently, your application will have problems with that approach,
1012 e.g., incorrect function-key definitions.
1014 If you set <STRONG>TERM</STRONG> in your environment, it has no effect on the operation
1015 of the terminal emulator. It only affects the way applications work
1016 within the terminal. Likewise, as a general rule (<STRONG>xterm</STRONG> being a rare
1017 exception), terminal emulators which allow you to specify <STRONG>TERM</STRONG> as a
1018 parameter or configuration value do not change their behavior to match

1023 If the <STRONG>ncurses</STRONG> library has been configured with <EM>termcap</EM> support,
1024 <STRONG>ncurses</STRONG> will check for a terminal's description in termcap form if it
1025 is not available in the terminfo database.
1027 The <STRONG>TERMCAP</STRONG> environment variable contains either a terminal description
1028 (with newlines stripped out), or a file name telling where the informa-
1029 tion denoted by the <STRONG>TERM</STRONG> environment variable exists. In either case,
1030 setting it directs <STRONG>ncurses</STRONG> to ignore the usual place for this informa-
1031 tion, e.g., /etc/termcap.

1035 <STRONG>ncurses</STRONG> can be configured to read from multiple terminal databases.
1036 The <STRONG>TERMINFO</STRONG> variable overrides the location for the default terminal
1037 database. Terminal descriptions (in terminal format) are stored in
1040 <STRONG>o</STRONG> Normally these are stored in a directory tree, using subdirectories
1041 named by the first letter of the terminal names therein.
1043 This is the scheme used in System V, which legacy Unix systems use,
1044 and the <STRONG>TERMINFO</STRONG> variable is used by <EM>curses</EM> applications on those
1045 systems to override the default location of the terminal database.
1047 <STRONG>o</STRONG> If <STRONG>ncurses</STRONG> is built to use hashed databases, then each entry in
1048 this list may be the path of a hashed database file, e.g.,
1050 /usr/share/terminfo.db
1054 /usr/share/terminfo/
1056 The hashed database uses less disk-space and is a little faster
1057 than the directory tree. However, some applications assume the
1058 existence of the directory tree, reading it directly rather than
1059 using the terminfo library calls.
1061 <STRONG>o</STRONG> If <STRONG>ncurses</STRONG> is built with a support for reading termcap files
1062 directly, then an entry in this list may be the path of a termcap
1065 <STRONG>o</STRONG> If the <STRONG>TERMINFO</STRONG> variable begins with "hex:" or "b64:", <STRONG>ncurses</STRONG> uses
1066 the remainder of that variable as a compiled terminal description.
1067 You might produce the base64 format using <STRONG><A HREF="infocmp.1m.html">infocmp(1m)</A></STRONG>:
1069 TERMINFO="$(infocmp -0 -Q2 -q)"
1072 The compiled description is used if it corresponds to the terminal
1073 identified by the <STRONG>TERM</STRONG> variable.
1075 Setting <STRONG>TERMINFO</STRONG> is the simplest, but not the only way to set location
1076 of the default terminal database. The complete list of database loca-
1077 tions in order follows:
1079 <STRONG>o</STRONG> the last terminal database to which <STRONG>ncurses</STRONG> wrote, if any, is
1082 <STRONG>o</STRONG> the location specified by the TERMINFO environment variable

1086 <STRONG>o</STRONG> locations listed in the TERMINFO_DIRS environment variable

1092 sponding to the TERMINFO_DIRS variable)

1099 Each location in the list is a terminal database as described in the
1100 section on the <STRONG>TERMINFO</STRONG> variable. The list is separated by colons
1101 (i.e., ":") on Unix, semicolons on OS/2 EMX.
1103 There is no corresponding feature in System V terminfo; it is an exten-
1104 sion developed for <STRONG>ncurses</STRONG>.

1108 If <STRONG>TERMCAP</STRONG> does not hold a file name then <STRONG>ncurses</STRONG> checks the <STRONG>TERMPATH</STRONG>
1109 environment variable. This is a list of filenames separated by spaces
1110 or colons (i.e., ":") on Unix, semicolons on OS/2 EMX.
1112 If the <STRONG>TERMPATH</STRONG> environment variable is not set, <STRONG>ncurses</STRONG> looks in the
1115 /etc/termcap, /usr/share/misc/termcap and $HOME/.termcap,
1119 The library may be configured to disregard the following variables when
1120 the current user is the superuser (root), or if the application uses
1121 setuid or setgid permissions:
1123 $TERMINFO, $TERMINFO_DIRS, $TERMPATH, as well as $HOME.
1126 </PRE><H2><a name="h2-ALTERNATE-CONFIGURATIONS">ALTERNATE CONFIGURATIONS</a></H2><PRE>
1127 Several different configurations are possible, depending on the config-
1128 ure script options used when building <STRONG>ncurses</STRONG>. There are a few main
1129 options whose effects are visible to the applications developer using
1130 <STRONG>ncurses</STRONG>:
1133 The standard include for <STRONG>ncurses</STRONG> is as noted in <STRONG>SYNOPSIS</STRONG>:
1135 <STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
1137 This option is used to avoid filename conflicts when <STRONG>ncurses</STRONG> is
1138 not the main implementation of curses of the computer. If <STRONG>ncurses</STRONG>
1139 is installed disabling overwrite, it puts its headers in a subdi-
1142 <STRONG>#include</STRONG> <STRONG><ncurses/curses.h></STRONG>
1144 It also omits a symbolic link which would allow you to use
1145 <STRONG>-lcurses</STRONG> to build executables.
1148 The configure script renames the library and (if the <STRONG>--dis-</STRONG>
1149 <STRONG>able-overwrite</STRONG> option is used) puts the header files in a differ-
1150 ent subdirectory. All of the library names have a "w" appended to
1151 them, i.e., instead of
1153 <STRONG>-lncurses</STRONG>
1157 <STRONG>-lncursesw</STRONG>
1159 You must also enable the wide-character features in the header
1160 file when compiling for the wide-character library to use the
1161 extended (wide-character) functions. The symbol which enables
1162 these features has changed since XSI Curses, Issue 4:
1164 <STRONG>o</STRONG> Originally, the wide-character feature required the symbol
1165 <STRONG>_XOPEN_SOURCE_EXTENDED</STRONG> but that was only valid for XPG4
1168 <STRONG>o</STRONG> Later, that was deemed conflicting with <STRONG>_XOPEN_SOURCE</STRONG> defined
1171 <STRONG>o</STRONG> As of mid-2018, none of the features in this implementation
1172 require a <STRONG>_XOPEN_SOURCE</STRONG> feature greater than 600. However,
1173 X/Open Curses, Issue 7 (2009) recommends defining it to 700.
1175 <STRONG>o</STRONG> Alternatively, you can enable the feature by defining
1176 <STRONG>NCURSES_WIDECHAR</STRONG> with the caveat that some other header file
1177 than <STRONG>curses.h</STRONG> may require a specific value for <STRONG>_XOPEN_SOURCE</STRONG>
1178 (or a system-specific symbol).
1180 The <STRONG>curses.h</STRONG> file which is installed for the wide-character
1181 library is designed to be compatible with the normal library's
1182 header. Only the size of the <STRONG>WINDOW</STRONG> structure differs, and very
1183 few applications require more than a pointer to <STRONG>WINDOW</STRONG>s.
1185 If the headers are installed allowing overwrite, the wide-charac-
1186 ter library's headers should be installed last, to allow applica-
1187 tions to be built using either library from the same set of head-
1191 The configure script renames the library. All of the library
1192 names have a "t" appended to them (before any "w" added by
1193 <STRONG>--enable-widec</STRONG>).
1195 The global variables such as <STRONG>LINES</STRONG> are replaced by macros to allow
1196 read-only access. At the same time, setter-functions are provided
1197 to set these values. Some applications (very few) may require
1198 changes to work with this convention.
1207 The shared and normal (static) library names differ by their suf-
1208 fixes, e.g., <STRONG>libncurses.so</STRONG> and <STRONG>libncurses.a</STRONG>. The debug and pro-
1209 filing libraries add a "_g" and a "_p" to the root names respec-
1210 tively, e.g., <STRONG>libncurses_g.a</STRONG> and <STRONG>libncurses_p.a</STRONG>.
1213 The <STRONG>trace</STRONG> function normally resides in the debug library, but it
1214 is sometimes useful to configure this in the shared library. Con-
1215 figure scripts should check for the function's existence rather
1216 than assuming it is always in the debug library.

1237 cap compiler in the <STRONG>ncurses</STRONG> startup code, at significant cost in core

1247 configured with a <STRONG>SIGWINCH</STRONG> handler.
1249 The <STRONG>ncurses</STRONG> library extends the fixed set of function key capabilities
1250 of terminals by allowing the application designer to define additional
1251 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

1254 The <STRONG>ncurses</STRONG> library can exploit the capabilities of terminals which
1255 implement the ISO-6429 SGR 39 and SGR 49 controls, which allow an
1256 application to reset the terminal to its original foreground and back-
1257 ground colors. From the users' perspective, the application is able to
1258 draw colored text on a background whose color is set independently,
1259 providing better control over color contrasts. See the <STRONG>default_col-</STRONG>

1274 sections of the library man pages.
1276 Unlike other implementations, this one checks parameters such as point-
1277 ers to WINDOW structures to ensure they are not null. The main reason
1278 for providing this behavior is to guard against programmer error. The
1279 standard interface does not provide a way for the library to tell an
1280 application which of several possible errors were detected. Relying on
1281 this (or some other) extension will adversely affect the portability of
1282 curses applications.

1301 See the <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG> manual page for details.
1303 <STRONG>o</STRONG> The WINDOW structure's internal details can be hidden from applica-

1317 tty driver. In this implementation, all padding is done by sending NUL
1318 bytes. This method is slightly more expensive, but narrows the inter-
1319 face to the UNIX kernel significantly and increases the package's
