        A  program  using  these  routines must be linked with the

        programs want this),  the  following  sequence  should  be
        used:

-       The  ncurses  library   permits   manipulation   of   data

-       part  of  a  CRT  screen.  A default window called stdscr,
-       which is the size of the  terminal  screen,  is  supplied.

        COLUMNS

+            ground and background color values with this environ-
+            ment   variable   by   proving   a   2-element  list:
+            foreground,background.  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 positive value from zero to the terminfo max_col-
+            ors value is allowed.
+
+       NCURSES_NO_HARD_TABS
+            Ncurses 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 stty 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
-            applications.  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.,   timing.    Unless   a  hardware  terminal  is
-            interfaced into a terminal concentrator  (which  does
-            flow  control),  it (or your application) must manage
-            dataflow, preventing overruns.  The cheapest solution
-            (no  hardware cost) is for your program to do this by
-            pausing  after  operations  that  the  terminal  does

+            described in the terminfo are known  to  be  missing.

+            Linux console emulator and  the  GNU  screen  program

+            variable for these.  For  other  special  cases,  you
+            should  set  this  environment  variable.  Doing this

ALTERNATE CONFIGURATIONS

+       Several  different  configurations are possible, depending
+       on  the  configure  script  options  used  when   building
+       ncurses.   There  are a few main options whose effects are
+       visible to the applications developer using ncurses:
+
+       --disable-overwrite
+            The standard include for ncurses is as noted in  SYN-
+            OPSIS:
+
+            #include <curses.h>
+
+            This  option is used to avoid filename conflicts when
+            ncurses is not the main implementation of  curses  of
+            the  computer.   If  ncurses  is  installed disabling
+            overwrite, it puts its  headers  in  a  subdirectory,
+            e.g.,
+
+            #include <ncurses/curses.h>
+
+            It  also  omits a symbolic link which would allow you
+            to use -lcurses to build executables.
+
+       --enable-widec
+            The configure script renames the library and (if  the
+            --disable-overwrite  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
+
+            -lncurses
+
+            you link with
+
+            -lncursesw
+
+            You must also define _XOPEN_SOURCE_EXTENDED when com-
+            piling  for  the  wide-character  library  to use the
+            extended (wide-character)  functions.   The  curses.h
+            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 WINDOW struc-
+            ture differs, and very few applications require  more
+            than  a  pointer  to  WINDOWs.   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.

+            The  shared  and normal (static) library names differ
+            by   their   suffixes,   e.g.,   libncurses.so    and
+            libncurses.a.   The debug and profiling libraries add

+            e.g., libncurses_g.a and libncurses_p.a.
+
+       --with-trace
+            The  trace  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.

-       In the XSI standard and  SVr4  manual  pages,  many  entry
-       points have prototype arguments of the for char *const (or
-       cchar_t  *const,  or  wchar_t  *const,  or  void  *const).
-       Depending  on  one's interpretation of the ANSI C standard
-       (see section 3.5.4.1), these declarations are  either  (a)
-       meaningless,   or   (b)   meaningless  and  illegal.   The
-       declaration const char  *x  is  a  modifiable  pointer  to
-       unmodifiable  data,  but char *const x' is an unmodifiable
-       pointer to modifiable data.  Given that C passes arguments
-       by  value,  <type>  *const  as  a  formal  type is at best
-       dubious.   Some  compilers  choke   on   the   prototypes.
-       Therefore,  in this implementation, they have been changed
-       to const <type> * globally.
