60 <H2>DESCRIPTION</H2><PRE>
61 The <STRONG>ncurses</STRONG> library routines give the user a terminal-
62 independent method of updating character screens with rea-
63 sonable optimization. This implementation is ``new
64 curses'' (ncurses) and is the approved replacement for
65 4.4BSD classic curses, which has been discontinued. This
66 describes <STRONG>ncurses</STRONG> version 5.9 (patch 20110404).
67
68 The <STRONG>ncurses</STRONG> library emulates the curses library of System
69 V Release 4 UNIX, and XPG4 (X/Open Portability Guide)
70 curses (also known as XSI curses). XSI stands for X/Open
71 System Interfaces Extension. The <STRONG>ncurses</STRONG> library is
72 freely redistributable in source form. Differences from
73 the SVr4 curses are summarized under the <STRONG>EXTENSIONS</STRONG> and
74 <STRONG>PORTABILITY</STRONG> sections below and described in detail in the
75 respective <STRONG>EXTENSIONS</STRONG>, <STRONG>PORTABILITY</STRONG> and <STRONG>BUGS</STRONG> sections of
76 individual man pages.
77
78 The <STRONG>ncurses</STRONG> library also provides many useful extensions,
79 i.e., features which cannot be implemented by a simple
80 add-on library but which require access to the internals
81 of the library.
82
83 A program using these routines must be linked with the
84 <STRONG>-lncurses</STRONG> option, or (if it has been generated) with the
85 debugging library <STRONG>-lncurses_g</STRONG>. (Your system integrator
86 may also have installed these libraries under the names
87 <STRONG>-lcurses</STRONG> and <STRONG>-lcurses_g</STRONG>.) The ncurses_g library generates
88 trace logs (in a file called 'trace' in the current direc-
89 tory) that describe curses actions. See also the section
90 on <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>.
91
92 The <STRONG>ncurses</STRONG> package supports: overall screen, window and
93 pad manipulation; output to windows and pads; reading ter-
94 minal input; control over terminal and <STRONG>curses</STRONG> input and
95 output options; environment query routines; color manipu-
96 lation; use of soft label keys; terminfo capabilities; and
97 access to low-level terminal-manipulation routines.
98
99 The library uses the locale which the calling program has
100 initialized. That is normally done with <STRONG>setlocale</STRONG>:
101
102 <STRONG>setlocale(LC_ALL,</STRONG> <STRONG>"");</STRONG>
103
104 If the locale is not initialized, the library assumes that
105 characters are printable as in ISO-8859-1, to work with
106 certain legacy programs. You should initialize the locale
107 and not rely on specific details of the library when the
108 locale has not been setup.
109
110 The function <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG> must be called to initial-
111 ize the library before any of the other routines that deal
112 with windows and screens are used. The routine <STRONG>endwin</STRONG>
113 must be called before exiting.
114
115 To get character-at-a-time input without echoing (most
116 interactive, screen oriented programs want this), the fol-
117 lowing sequence should be used:
118
119 <STRONG>initscr();</STRONG> <STRONG>cbreak();</STRONG> <STRONG>noecho();</STRONG>
120
121 Most programs would additionally use the sequence:
122
123 <STRONG>nonl();</STRONG>
124 <STRONG>intrflush(stdscr,</STRONG> <STRONG>FALSE);</STRONG>
125 <STRONG>keypad(stdscr,</STRONG> <STRONG>TRUE);</STRONG>
126
127 Before a <STRONG>curses</STRONG> program is run, the tab stops of the ter-
128 minal should be set and its initialization strings, if
129 defined, must be output. This can be done by executing
130 the <STRONG>tput</STRONG> <STRONG>init</STRONG> command after the shell environment variable
131 <STRONG>TERM</STRONG> has been exported. <STRONG>tset(1)</STRONG> is usually responsible
132 for doing this. [See <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for further details.]
133
134 The <STRONG>ncurses</STRONG> library permits manipulation of data struc-
135 tures, called <EM>windows</EM>, which can be thought of as two-
136 dimensional arrays of characters representing all or part
137 of a CRT screen. A default window called <STRONG>stdscr</STRONG>, which is
138 the size of the terminal screen, is supplied. Others may
139 be created with <STRONG>newwin</STRONG>.
140
141 Note that <STRONG>curses</STRONG> does not handle overlapping windows,
142 that's done by the <STRONG><A HREF="panel.3x.html">panel(3x)</A></STRONG> library. This means that you
143 can either use <STRONG>stdscr</STRONG> or divide the screen into tiled win-
144 dows and not using <STRONG>stdscr</STRONG> at all. Mixing the two will
145 result in unpredictable, and undesired, effects.
146
147 Windows are referred to by variables declared as <STRONG>WINDOW</STRONG> <STRONG>*</STRONG>.
148 These data structures are manipulated with routines
149 described here and elsewhere in the <STRONG>ncurses</STRONG> manual pages.
150 Among those, the most basic routines are <STRONG>move</STRONG> and <STRONG>addch</STRONG>.
151 More general versions of these routines are included with
152 names beginning with <STRONG>w</STRONG>, allowing the user to specify a
153 window. The routines not beginning with <STRONG>w</STRONG> affect <STRONG>stdscr</STRONG>.
154
155 After using routines to manipulate a window, <STRONG>refresh</STRONG> is
156 called, telling <STRONG>curses</STRONG> to make the user's CRT screen look
157 like <STRONG>stdscr</STRONG>. The characters in a window are actually of
158 type <STRONG>chtype</STRONG>, (character and attribute data) so that other
159 information about the character may also be stored with
160 each character.
161
162 Special windows called <EM>pads</EM> may also be manipulated.
163 These are windows which are not constrained to the size of
164 the screen and whose contents need not be completely dis-
165 played. See <STRONG><A HREF="curs_pad.3x.html">curs_pad(3x)</A></STRONG> for more information.
166
167 In addition to drawing characters on the screen, video
168 attributes and colors may be supported, causing the char-
169 acters to show up in such modes as underlined, in reverse
170 video, or in color on terminals that support such display
171 enhancements. Line drawing characters may be specified to
172 be output. On input, <STRONG>curses</STRONG> is also able to translate
173 arrow and function keys that transmit escape sequences
174 into single values. The video attributes, line drawing
175 characters, and input values use names, defined in
176 <STRONG>&lt;curses.h&gt;</STRONG>, such as <STRONG>A_REVERSE</STRONG>, <STRONG>ACS_HLINE</STRONG>, and <STRONG>KEY_LEFT</STRONG>.
177
178 If the environment variables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> are set, or
179 if the program is executing in a window environment, line
180 and column information in the environment will override
181 information read by <EM>terminfo</EM>. This would affect a program
182 running in an AT&amp;T 630 layer, for example, where the size
183 of a screen is changeable (see <STRONG>ENVIRONMENT</STRONG>).
184
185 If the environment variable <STRONG>TERMINFO</STRONG> is defined, any pro-
186 gram using <STRONG>curses</STRONG> checks for a local terminal definition
187 before checking in the standard place. For example, if
188 <STRONG>TERM</STRONG> is set to <STRONG>att4424</STRONG>, then the compiled terminal defini-
189 tion is found in
190
191 <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
192
193 (The <STRONG>a</STRONG> is copied from the first letter of <STRONG>att4424</STRONG> to avoid
194 creation of huge directories.) However, if <STRONG>TERMINFO</STRONG> is
195 set to <STRONG>$HOME/myterms</STRONG>, <STRONG>curses</STRONG> first checks
196
197 <STRONG>$HOME/myterms/a/att4424</STRONG>,
198
199 and if that fails, it then checks
200
201 <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
202
203 This is useful for developing experimental definitions or
204 when write permission in <STRONG>/usr/share/terminfo</STRONG> is not avail-
205 able.
206
207 The integer variables <STRONG>LINES</STRONG> and <STRONG>COLS</STRONG> are defined in
208 <STRONG>&lt;curses.h&gt;</STRONG> and will be filled in by <STRONG>initscr</STRONG> with the size
209 of the screen. The constants <STRONG>TRUE</STRONG> and <STRONG>FALSE</STRONG> have the val-
210 ues <STRONG>1</STRONG> and <STRONG>0</STRONG>, respectively.
211
212 The <STRONG>curses</STRONG> routines also define the <STRONG>WINDOW</STRONG> <STRONG>*</STRONG> variable
213 <STRONG>curscr</STRONG> which is used for certain low-level operations like
214 clearing and redrawing a screen containing garbage. The
215 <STRONG>curscr</STRONG> can be used in only a few routines.
216
217 <STRONG>Routine</STRONG> <STRONG>and</STRONG> <STRONG>Argument</STRONG> <STRONG>Names</STRONG>
218 Many <STRONG>curses</STRONG> routines have two or more versions. The rou-
219 tines prefixed with <STRONG>w</STRONG> require a window argument. The rou-
220 tines prefixed with <STRONG>p</STRONG> require a pad argument. Those with-
221 out a prefix generally use <STRONG>stdscr</STRONG>.
222
223 The routines prefixed with <STRONG>mv</STRONG> require a <EM>y</EM> and <EM>x</EM> coordinate
224 to move to before performing the appropriate action. The
225 <STRONG>mv</STRONG> routines imply a call to <STRONG>move</STRONG> before the call to the
226 other routine. The coordinate <EM>y</EM> always refers to the row
227 (of the window), and <EM>x</EM> always refers to the column. The
228 upper left-hand corner is always (0,0), not (1,1).
229
230 The routines prefixed with <STRONG>mvw</STRONG> take both a window argument
231 and <EM>x</EM> and <EM>y</EM> coordinates. The window argument is always
232 specified before the coordinates.
233
234 In each case, <EM>win</EM> is the window affected, and <EM>pad</EM> is the
235 pad affected; <EM>win</EM> and <EM>pad</EM> are always pointers to type <STRONG>WIN-</STRONG>
236 <STRONG>DOW</STRONG>.
237
238 Option setting routines require a Boolean flag <EM>bf</EM> with the
239 value <STRONG>TRUE</STRONG> or <STRONG>FALSE</STRONG>; <EM>bf</EM> is always of type <STRONG>bool</STRONG>. Most of
240 the data types used in the library routines, such as <STRONG>WIN-</STRONG>
241 <STRONG>DOW</STRONG>, <STRONG>SCREEN</STRONG>, <STRONG>bool</STRONG>, and <STRONG>chtype</STRONG> are defined in <STRONG>&lt;curses.h&gt;</STRONG>.
242 Types used for the terminfo routines such as <STRONG>TERMINAL</STRONG> are
243 defined in <STRONG>&lt;term.h&gt;</STRONG>.
244
245 This manual page describes functions which may appear in
246 any configuration of the library. There are two common
247 configurations of the library:
248
249 ncurses
250 the "normal" library, which handles 8-bit
251 characters. The normal (8-bit) library stores
252 characters combined with attributes in <STRONG>chtype</STRONG>
253 data.
254
255 Attributes alone (no corresponding character)
256 may be stored in <STRONG>chtype</STRONG> or the equivalent
257 <STRONG>attr_t</STRONG> data. In either case, the data is
258 stored in something like an integer.
259
260 Each cell (row and column) in a <STRONG>WINDOW</STRONG> is
261 stored as a <STRONG>chtype</STRONG>.
262
263 ncursesw
264 the so-called "wide" library, which handles
265 multibyte characters (see the section on
266 <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>). The "wide" library
267 includes all of the calls from the "normal"
268 library. It adds about one third more calls
269 using data types which store multibyte charac-
270 ters:
271
272 <STRONG>cchar_t</STRONG>
273 corresponds to <STRONG>chtype</STRONG>. However it is a
274 structure, because more data is stored
275 than can fit into an integer. The char-
276 acters are large enough to require a full
277 integer value - and there may be more
278 than one character per cell. The video
279 attributes and color are stored in sepa-
280 rate fields of the structure.
281
282 Each cell (row and column) in a <STRONG>WINDOW</STRONG> is
283 stored as a <STRONG>cchar_t</STRONG>.
284
285 <STRONG>wchar_t</STRONG>
286 stores a "wide" character. Like <STRONG>chtype</STRONG>,
287 this may be an integer.
288
289 <STRONG>wint_t</STRONG>
290 stores a <STRONG>wchar_t</STRONG> or <STRONG>WEOF</STRONG> - not the same,
291 though both may have the same size.
292
293 The "wide" library provides new functions
294 which are analogous to functions in the "nor-
295 mal" library. There is a naming convention
296 which relates many of the normal/wide vari-
297 ants: a "_w" is inserted into the name. For
298 example, <STRONG>waddch</STRONG> becomes <STRONG>wadd_wch</STRONG>.
299
300
301 <STRONG>Routine</STRONG> <STRONG>Name</STRONG> <STRONG>Index</STRONG>
302 The following table lists each <STRONG>curses</STRONG> routine and the name
303 of the manual page on which it is described. Routines
304 flagged with `*' are ncurses-specific, not described by
305 XPG4 or present in SVr4.

754 <H2>RETURN VALUE</H2><PRE>
755 Routines that return an integer return <STRONG>ERR</STRONG> upon failure
756 and an integer value other than <STRONG>ERR</STRONG> upon successful com-
757 pletion, unless otherwise noted in the routine descrip-
758 tions.
759
760 All macros return the value of the <STRONG>w</STRONG> version, except
761 <STRONG>setscrreg</STRONG>, <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>, <STRONG>getbegyx</STRONG>, and <STRONG>getmaxyx</STRONG>. The
762 return values of <STRONG>setscrreg</STRONG>, <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>, <STRONG>getbegyx</STRONG>,
763 and <STRONG>getmaxyx</STRONG> are undefined (i.e., these should not be used
764 as the right-hand side of assignment statements).
765
766 Routines that return pointers return <STRONG>NULL</STRONG> on error.
767
768
769 </PRE>
770 <H2>ENVIRONMENT</H2><PRE>
771 The following environment symbols are useful for customiz-
772 ing the runtime behavior of the <STRONG>ncurses</STRONG> library. The most
773 important ones have been already discussed in detail.
774
775 BAUDRATE
776 The debugging library checks this environment symbol
777 when the application has redirected output to a file.
778 The symbol's numeric value is used for the baudrate.
779 If no value is found, <STRONG>ncurses</STRONG> uses 9600. This allows
780 testers to construct repeatable test-cases that take
781 into account costs that depend on baudrate.
782
783 CC When set, change occurrences of the command_character
784 (i.e., the <STRONG>cmdch</STRONG> capability) of the loaded terminfo
785 entries to the value of this symbol. Very few ter-
786 minfo entries provide this feature.
787
788 Because this name is also used in development envi-
789 ronments to represent the C compiler's name, <STRONG>ncurses</STRONG>
790 ignores it if it does not happen to be a single char-
791 acter.
792
793 COLUMNS
794 Specify the width of the screen in characters.
795 Applications running in a windowing environment usu-
796 ally are able to obtain the width of the window in
797 which they are executing. If neither the <STRONG>COLUMNS</STRONG>
798 value nor the terminal's screen size is available,
799 <STRONG>ncurses</STRONG> uses the size which may be specified in the
800 terminfo database (i.e., the <STRONG>cols</STRONG> capability).
801
802 It is important that your application use a correct
803 size for the screen. This is not always possible
804 because your application may be running on a host
805 which does not honor NAWS (Negotiations About Window
806 Size), or because you are temporarily running as
807 another user. However, setting <STRONG>COLUMNS</STRONG> and/or <STRONG>LINES</STRONG>
808 overrides the library's use of the screen size
809 obtained from the operating system.
810
811 Either <STRONG>COLUMNS</STRONG> or <STRONG>LINES</STRONG> symbols may be specified
812 independently. This is mainly useful to circumvent
813 legacy misfeatures of terminal descriptions, e.g.,
814 xterm which commonly specifies a 65 line screen. For
815 best results, <STRONG>lines</STRONG> and <STRONG>cols</STRONG> should not be specified
816 in a terminal description for terminals which are run
817 as emulations.
818
819 Use the <STRONG>use_env</STRONG> function to disable all use of exter-
820 nal environment (including system calls) to determine
821 the screen size.
822
823 ESCDELAY
824 Specifies the total time, in milliseconds, for which
825 ncurses will await a character sequence, e.g., a
826 function key. The default value, 1000 milliseconds,
827 is enough for most uses. However, it is made a vari-
828 able to accommodate unusual applications.
829
830 The most common instance where you may wish to change
831 this value is to work with slow hosts, e.g., running
832 on a network. If the host cannot read characters
833 rapidly enough, it will have the same effect as if
834 the terminal did not send characters rapidly enough.
835 The library will still see a timeout.
836
837 Note that xterm mouse events are built up from char-
838 acter sequences received from the xterm. If your
839 application makes heavy use of multiple-clicking, you
840 may wish to lengthen this default value because the
841 timeout applies to the composed multi-click event as
842 well as the individual clicks.
843
844 In addition to the environment variable, this imple-
845 mentation provides a global variable with the same
846 name. Portable applications should not rely upon the
847 presence of ESCDELAY in either form, but setting the
848 environment variable rather than the global variable
849 does not create problems when compiling an applica-
850 tion.
851
852 HOME Tells <STRONG>ncurses</STRONG> where your home directory is. That is
853 where it may read and write auxiliary terminal
854 descriptions:
855
856 $HOME/.termcap
857 $HOME/.terminfo
858
859 LINES
860 Like COLUMNS, specify the height of the screen in
861 characters. See COLUMNS for a detailed description.
862
863 MOUSE_BUTTONS_123
864 This applies only to the OS/2 EMX port. It specifies
865 the order of buttons on the mouse. OS/2 numbers a
866 3-button mouse inconsistently from other platforms:
867
868 1 = left
869 2 = right
870 3 = middle.
871
872 This symbol lets you customize the mouse. The symbol
873 must be three numeric digits 1-3 in any order, e.g.,
874 123 or 321. If it is not specified, <STRONG>ncurses</STRONG> uses
875 132.
876
877 NCURSES_ASSUMED_COLORS
878 Override the compiled-in assumption that the termi-
879 nal's default colors are white-on-black (see
880 <STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG>). You may set the foreground and
881 background color values with this environment vari-
882 able by proving a 2-element list: foreground,back-
883 ground. For example, to tell ncurses to not assume
884 anything about the colors, set this to "-1,-1". To
885 make it green-on-black, set it to "2,0". Any posi-
886 tive value from zero to the terminfo <STRONG>max_colors</STRONG> value
887 is allowed.
888
889 NCURSES_GPM_TERMS
890 This applies only to ncurses configured to use the
891 GPM interface.
892
893 If present, the environment variable is a list of one
894 or more terminal names against which the TERM envi-
895 ronment variable is matched. Setting it to an empty
896 value disables the GPM interface; using the built-in
897 support for xterm, etc.
898
899 If the environment variable is absent, ncurses will
900 attempt to open GPM if TERM contains "linux".
901
902 NCURSES_NO_HARD_TABS
903 <STRONG>Ncurses</STRONG> may use tabs as part of the cursor movement
904 optimization. In some cases, your terminal driver
905 may not handle these properly. Set this environment
906 variable to disable the feature. You can also adjust
907 your <STRONG>stty</STRONG> settings to avoid the problem.
908
909 NCURSES_NO_MAGIC_COOKIES
910 Some terminals use a magic-cookie feature which
911 requires special handling to make highlighting and
912 other video attributes display properly. You can
913 suppress the highlighting entirely for these termi-
914 nals by setting this environment variable.
915
916 NCURSES_NO_PADDING
917 Most of the terminal descriptions in the terminfo
918 database are written for real "hardware" terminals.
919 Many people use terminal emulators which run in a
920 windowing environment and use curses-based applica-
921 tions. Terminal emulators can duplicate all of the
922 important aspects of a hardware terminal, but they do
923 not have the same limitations. The chief limitation
924 of a hardware terminal from the standpoint of your
925 application is the management of dataflow, i.e., tim-
926 ing. Unless a hardware terminal is interfaced into a
927 terminal concentrator (which does flow control), it
928 (or your application) must manage dataflow, prevent-
929 ing overruns. The cheapest solution (no hardware
930 cost) is for your program to do this by pausing after
931 operations that the terminal does slowly, such as
932 clearing the display.
933
934 As a result, many terminal descriptions (including
935 the vt100) have delay times embedded. You may wish
936 to use these descriptions, but not want to pay the
937 performance penalty.
938
939 Set the NCURSES_NO_PADDING symbol to disable all but
940 mandatory padding. Mandatory padding is used as a
941 part of special control sequences such as <EM>flash</EM>.
942
943 NCURSES_NO_SETBUF
944 Normally <STRONG>ncurses</STRONG> enables buffered output during ter-
945 minal initialization. This is done (as in SVr4
946 curses) for performance reasons. For testing pur-
947 poses, both of <STRONG>ncurses</STRONG> and certain applications, this
948 feature is made optional. Setting the
949 NCURSES_NO_SETBUF variable disables output buffering,
950 leaving the output in the original (usually line
951 buffered) mode.
952
953 NCURSES_NO_UTF8_ACS
954 During initialization, the <STRONG>ncurses</STRONG> library checks for
955 special cases where VT100 line-drawing (and the cor-
956 responding alternate character set capabilities)
957 described in the terminfo are known to be missing.
958 Specifically, when running in a UTF-8 locale, the
959 Linux console emulator and the GNU screen program
960 ignore these. Ncurses checks the TERM environment
961 variable for these. For other special cases, you
962 should set this environment variable. Doing this
963 tells ncurses to use Unicode values which correspond
964 to the VT100 line-drawing glyphs. That works for the
965 special cases cited, and is likely to work for termi-
966 nal emulators.
967
968 When setting this variable, you should set it to a
969 nonzero value. Setting it to zero (or to a nonnum-
970 ber) disables the special check for "linux" and
971 "screen".
972
973 As an alternative to the environment variable,
974 ncurses checks for an extended terminfo capability
975 <STRONG>U8</STRONG>. This is a numeric capability which can be com-
976 piled using <STRONG>tic</STRONG> <STRONG>-x</STRONG>. For example
977
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,
981 U8#0, use=linux,
982
983 # uxterm with vt100Graphics resource set to false
984 xterm-utf8|xterm relying on UTF-8 line-graphics,
985 U8#1, use=xterm,
986
987 The name "U8" is chosen to be two characters, to per-
988 mit it to be used by applications that use ncurses'
989 termcap interface.
990
991 NCURSES_TRACE
992 During initialization, the <STRONG>ncurses</STRONG> debugging library
993 checks the NCURSES_TRACE symbol. If it is defined,
994 to a numeric value, <STRONG>ncurses</STRONG> calls the <STRONG>trace</STRONG> function,
995 using that value as the argument.
996
997 The argument values, which are defined in <STRONG>curses.h</STRONG>,
998 provide several types of information. When running
999 with traces enabled, your application will write the
1000 file <STRONG>trace</STRONG> to the current directory.
1001
1002 TERM Denotes your terminal type. Each terminal type is
1003 distinct, though many are similar.
1004
1005 TERMCAP
1006 If the <STRONG>ncurses</STRONG> library has been configured with <EM>term-</EM>
1007 <EM>cap</EM> support, <STRONG>ncurses</STRONG> will check for a terminal's
1008 description in termcap form if it is not available in
1009 the terminfo database.
1010
1011 The TERMCAP symbol contains either a terminal
1012 description (with newlines stripped out), or a file
1013 name telling where the information denoted by the
1014 TERM symbol exists. In either case, setting it
1015 directs <STRONG>ncurses</STRONG> to ignore the usual place for this
1016 information, e.g., /etc/termcap.
1017
1018 TERMINFO
1019 Overrides the directory in which <STRONG>ncurses</STRONG> searches for
1020 your terminal description. This is the simplest, but
1021 not the only way to change the list of directories.
1022 The complete list of directories in order follows:
1023
1024 <STRONG>o</STRONG> the last directory to which <STRONG>ncurses</STRONG> wrote, if
1025 any, is searched first
1026
1027 <STRONG>o</STRONG> the directory specified by the TERMINFO symbol
1028
1029 <STRONG>o</STRONG> $HOME/.terminfo
1030
1031 <STRONG>o</STRONG> directories listed in the TERMINFO_DIRS symbol
1032
1033 <STRONG>o</STRONG> one or more directories whose names are config-
1034 ured and compiled into the ncurses library, e.g.,
1035 /usr/share/terminfo
1036
1037 TERMINFO_DIRS
1038 Specifies a list of directories to search for termi-
1039 nal descriptions. The list is separated by colons
1040 (i.e., ":") on Unix, semicolons on OS/2 EMX. All of
1041 the terminal descriptions are in terminfo form, which
1042 makes a subdirectory named for the first letter of
1043 the terminal names therein.
1044
1045 TERMPATH
1046 If TERMCAP does not hold a file name then <STRONG>ncurses</STRONG>
1047 checks the TERMPATH symbol. This is a list of file-
1048 names separated by spaces or colons (i.e., ":") on
1049 Unix, semicolons on OS/2 EMX. If the TERMPATH symbol
1050 is not set, <STRONG>ncurses</STRONG> looks in the files /etc/termcap,
1051 /usr/share/misc/termcap and $HOME/.termcap, in that
1052 order.
1053
1054 The library may be configured to disregard the following
1055 variables when the current user is the superuser (root),
1056 or if the application uses setuid or setgid permissions:
1057 $TERMINFO, $TERMINFO_DIRS, $TERMPATH, as well as $HOME.

1061 <H2>ALTERNATE CONFIGURATIONS</H2><PRE>
1062 Several different configurations are possible, depending
1063 on the configure script options used when building
1064 <STRONG>ncurses</STRONG>. There are a few main options whose effects are
1065 visible to the applications developer using <STRONG>ncurses</STRONG>:
1066
1067 --disable-overwrite
1068 The standard include for <STRONG>ncurses</STRONG> is as noted in <STRONG>SYN-</STRONG>
1069 <STRONG>OPSIS</STRONG>:
1070
1071 <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</STRONG>
1072
1073 This option is used to avoid filename conflicts when
1074 <STRONG>ncurses</STRONG> is not the main implementation of curses of
1075 the computer. If <STRONG>ncurses</STRONG> is installed disabling
1076 overwrite, it puts its headers in a subdirectory,
1077 e.g.,
1078
1079 <STRONG>#include</STRONG> <STRONG>&lt;ncurses/curses.h&gt;</STRONG>
1080
1081 It also omits a symbolic link which would allow you
1082 to use <STRONG>-lcurses</STRONG> to build executables.
1083
1084 --enable-widec
1085 The configure script renames the library and (if the
1086 <STRONG>--disable-overwrite</STRONG> option is used) puts the header
1087 files in a different subdirectory. All of the
1088 library names have a "w" appended to them, i.e.,
1089 instead of
1090
1091 <STRONG>-lncurses</STRONG>
1092
1093 you link with
1094
1095 <STRONG>-lncursesw</STRONG>
1096
1097 You must also define <STRONG>_XOPEN_SOURCE_EXTENDED</STRONG> when com-
1098 piling for the wide-character library to use the
1099 extended (wide-character) functions. The <STRONG>curses.h</STRONG>
1100 file which is installed for the wide-character
1101 library is designed to be compatible with the normal
1102 library's header. Only the size of the <STRONG>WINDOW</STRONG> struc-
1103 ture differs, and very few applications require more
1104 than a pointer to <STRONG>WINDOW</STRONG>s. If the headers are
1105 installed allowing overwrite, the wide-character
1106 library's headers should be installed last, to allow
1107 applications to be built using either library from
1108 the same set of headers.
1109
1110 --with-shared
1111
1112 --with-normal
1113
1114 --with-debug
1115
1116 --with-profile
1117 The shared and normal (static) library names differ
1118 by their suffixes, e.g., <STRONG>libncurses.so</STRONG> and
1119 <STRONG>libncurses.a</STRONG>. The debug and profiling libraries add
1120 a "_g" and a "_p" to the root names respectively,
1121 e.g., <STRONG>libncurses_g.a</STRONG> and <STRONG>libncurses_p.a</STRONG>.
1122
1123 --with-trace
1124 The <STRONG>trace</STRONG> function normally resides in the debug
1125 library, but it is sometimes useful to configure this
1126 in the shared library. Configure scripts should
1127 check for the function's existence rather than assum-
1128 ing it is always in the debug library.

1147 <H2>EXTENSIONS</H2><PRE>
1148 The <STRONG>ncurses</STRONG> library can be compiled with an option
1149 (<STRONG>-DUSE_GETCAP</STRONG>) that falls back to the old-style /etc/term-
1150 cap file if the terminal setup code cannot find a terminfo
1151 entry corresponding to <STRONG>TERM</STRONG>. Use of this feature is not
1152 recommended, as it essentially includes an entire termcap
1153 compiler in the <STRONG>ncurses</STRONG> startup code, at significant cost
1154 in core and startup cycles.
1155
1156 The <STRONG>ncurses</STRONG> library includes facilities for capturing
1157 mouse events on certain terminals (including xterm). See
1158 the <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> manual page for details.
1159
1160 The <STRONG>ncurses</STRONG> library includes facilities for responding to
1161 window resizing events, e.g., when running in an xterm.
1162 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
1163 details. In addition, the library may be configured with
1164 a SIGWINCH handler.
1165
1166 The <STRONG>ncurses</STRONG> library extends the fixed set of function key
1167 capabilities of terminals by allowing the application
1168 designer to define additional key sequences at runtime.
1169 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-
1170 ual pages for details.
1171
1172 The <STRONG>ncurses</STRONG> library can exploit the capabilities of termi-
1173 nals which implement the ISO-6429 SGR 39 and SGR 49 con-
1174 trols, which allow an application to reset the terminal to
1175 its original foreground and background colors. From the
1176 users' perspective, the application is able to draw col-
1177 ored text on a background whose color is set indepen-
1178 dently, providing better control over color contrasts.
1179 See the <STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG> manual page for details.
1180
1181 The <STRONG>ncurses</STRONG> library includes a function for directing
1182 application output to a printer attached to the terminal
1183 device. See the <STRONG><A HREF="curs_print.3x.html">curs_print(3x)</A></STRONG> manual page for details.
1184
1185
1186 </PRE>
1187 <H2>PORTABILITY</H2><PRE>
1188 The <STRONG>ncurses</STRONG> library is intended to be BASE-level confor-
1189 mant with XSI Curses. The EXTENDED XSI Curses functional-
1190 ity (including color support) is supported.
1191
1192 A small number of local differences (that is, individual
1193 differences between the XSI Curses and <STRONG>ncurses</STRONG> calls) are
1194 described in <STRONG>PORTABILITY</STRONG> sections of the library man
1195 pages.
1196
1197 This implementation also contains several extensions:
1198
1199 <STRONG>o</STRONG> The routine <STRONG>has_key</STRONG> is not part of XPG4, nor is it
1200 present in SVr4. See the <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG> manual page
1201 for details.
1202
1203 <STRONG>o</STRONG> The routine <STRONG>slk_attr</STRONG> is not part of XPG4, nor is it
1204 present in SVr4. See the <STRONG><A HREF="curs_slk.3x.html">curs_slk(3x)</A></STRONG> manual page for
1205 details.
1206
1207 <STRONG>o</STRONG> The routines <STRONG>getmouse</STRONG>, <STRONG>mousemask</STRONG>, <STRONG>ungetmouse</STRONG>, <STRONG>mousein-</STRONG>
1208 <STRONG>terval</STRONG>, and <STRONG>wenclose</STRONG> relating to mouse interfacing are
1209 not part of XPG4, nor are they present in SVr4. See
1210 the <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> manual page for details.
1211
1212 <STRONG>o</STRONG> The routine <STRONG>mcprint</STRONG> was not present in any previous
1213 curses implementation. See the <STRONG><A HREF="curs_print.3x.html">curs_print(3x)</A></STRONG> manual
1214 page for details.
1215
1216 <STRONG>o</STRONG> The routine <STRONG>wresize</STRONG> is not part of XPG4, nor is it
1217 present in SVr4. See the <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG> manual page for
1218 details.
1219
1220 <STRONG>o</STRONG> The WINDOW structure's internal details can be hidden
1221 from application programs. See <STRONG><A HREF="curs_opaque.3x.html">curs_opaque(3x)</A></STRONG> for
1222 the discussion of <STRONG>is_scrollok</STRONG>, etc.
1223
1224 <STRONG>o</STRONG> This implementation can be configured to provide rudi-
1225 mentary support for multi-threaded applications. See
1226 <STRONG><A HREF="curs_threads.3x.html">curs_threads(3x)</A></STRONG> for details.
1227
1228 <STRONG>o</STRONG> This implementation can also be configured to provide
1229 a set of functions which improve the ability to manage
1230 multiple screens. See <STRONG><A HREF="curs_sp_funcs.3x.html">curs_sp_funcs(3x)</A></STRONG> for details.
1231
1232 In historic curses versions, delays embedded in the capa-
1233 bilities <STRONG>cr</STRONG>, <STRONG>ind</STRONG>, <STRONG>cub1</STRONG>, <STRONG>ff</STRONG> and <STRONG>tab</STRONG> activated corresponding
1234 delay bits in the UNIX tty driver. In this implementa-
1235 tion, all padding is done by sending NUL bytes. This
1236 method is slightly more expensive, but narrows the inter-
1237 face to the UNIX kernel significantly and increases the
1238 package's portability correspondingly.
