To avoid confusion, zap libcurses. ncurses provides both curses, termcap

and termlib (terminfo) support.

-.pp
-The WINDOW structure is defined as follows:
-.(l I
-.so win_st.gr
-.)l
-.pp
-.Vn \*_cury \\*
-.(f
-\**
-All variables not normally accessed directly by the user
-are named with an initial
-.Bq \*_
-to avoid conflicts with the user's variables.
-.)f
-and
-.Vn \*_curx
-are the current \*y for the window.
-New characters added to the screen
-are added at this point.
-.Vn \*_maxy
-and
-.Vn \*_maxx
-are the maximum values allowed for
-.Vn \*_cury\*,\*_curx ). (
-.Vn \*_begy
-and
-.Vn \*_begx
-are the starting \*y on the terminal for the window,
-.i i.e. ,
-the window's home.
-.Vn \*_cury ,
-.Vn \*_curx ,
-.Vn \*_maxy ,
-and
-.Vn \*_maxx
-are measured relative to
-.Vn \*_begy\*,\*_begx ), (
-not the terminal's home.
-.pp
-.Vn \*_clear
-tells if a clear-screen sequence is to be generated
-on the next
-.Fn refresh
-call.
-This is only meaningful for screens.
-The initial clear-screen for the first
-.Fn refresh
-call is generated by initially setting clear to be TRUE for
-.Vn curscr ,
-which always generates a clear-screen if set,
-irrelevant of the dimensions of the window involved.
-.Vn \*_leave
-is TRUE if the current \*y and the cursor
-are to be left after the last character changed on the terminal,
-or not moved if there is no change.
-.Vn \*_scroll
-is TRUE
-if scrolling is allowed.
-.pp
-.Vn \*_y
-is a pointer to an array of lines which describe the terminal.
-Thus:
-.(l
-\*_y[i]
-.)l
-.lp
-is a pointer to the
-.Vn i th
-line, and
-.(l
-\*_y[i][j]
-.)l
-.lp
-is the
-.Vn j th
-character on the
-.Vn i th
-line.
-.Vn \*_flags
-can have one or more values
-or'd into it.
-.pp
-For windows that are not subwindows,
-.Vn \*_orig
-is
-NULL .
-For subwindows,
-it points to the main window
-to which the window is subsidiary.
-.Vn \*_nextp
-is a pointer in a circularly linked list
-of all the windows which are subwindows of the same main window,
-plus the main window itself.
-.pp
-.Vn \*_firstch
-and
-.Vn \*_lastch
-are
-.Fn malloc ed
-arrays which contain the index of the
-first and last changed characters
-on the line.
-.Vn \*_ch\*_off
-is the x offset for the window
-in the
-.Vn \*_firstch
-and
-.Vn \*_lastch
-arrays for this window.
-For main windows,
-this is always 0;
-for subwindows
-it is the difference between the starting point of the main window
-and that of the subindow,
-so that change markers can be set relative to the main window.
-This makes these markers global in scope.
-.pp
-All subwindows share the appropriate portions of
-.Vn _y ,
-.Vn _firstch ,
-.Vn _lastch ,
-and
-.Vn _insdel
-with their main window.
-.pp
-.b \*_ENDLINE
-says that the end of the line for this window
-is also the end of a screen.
-.b \*_FULLWIN
-says that this window is a screen.
-.b \*_SCROLLWIN
-indicates that the last character of this screen
-is at the lower right-hand corner of the terminal;
-.i i.e. ,
-if a character was put there,
-the terminal would scroll.
-.b \*_FULLLINE
-says that the width of a line is the same as the width of the terminal.
-If
-.b \*_FLUSH
-is set,
-it says that
-.Fn fflush "" "" stdout
-should be called at the end of each
-.Fn refresh
-.b \*_STANDOUT
-says that all characters added to the screen
-are in standout mode.
-.b \*_INSDEL
-is reserved for future use,
-and is set by
-.Fn idlok .
-.Vn \*_firstch
-is set to
-.b \*_NOCHANGE
-for lines on which there has been no change
-since the last
-.Fn refresh .

-.i systat(1) .
-.sh 2 "Screen Updating"
-.pp
-The following examples are intended to demonstrate
-the basic structure of a program
-using the screen updating sections of the package.
-Several of the programs require calculational sections
-which are irrelevant of to the example,
-and are therefore usually not included.
-It is hoped that the data structure definitions
-give enough of an idea to allow understanding
-of what the relevant portions do.
-.sh 3 "Simple Character Output"

-This is a moderately simple program which prints

-It is more efficient to write this
-using only the motion optimization,

-.(l I

-.)l
-.sh 3 "Life"
-.pp
-This program fragment models the famous computer pattern game of life
-(Scientific American, May, 1974).
-The calculational routines create a linked list of structures
-defining where each piece is.
-Nothing here claims to be optimal,
-merely demonstrative.
-This code, however,
-is a very good place to use the screen updating routines,
-as it allows them to worry about what the last position looked like,
-so you don't have to.
-It also demonstrates some of the input routines.
-.(l I
-.so life.gr
-.)l
-.sh 2 "Motion optimization"
-.pp
-The following example shows how motion optimization
-is written on its own.
-Programs which flit from one place to another without
-regard for what is already there
-usually do not need the overhead of both space and time
-associated with screen updating.
-They should instead use motion optimization.
-.sh 3 "Twinkle"
-.pp
-The
-.b twinkle
-program
-is a good candidate for simple motion optimization.
-Here is how it could be written
-(only the routines that have been changed are shown):

-.pp
-Here we present a few examples
-of how to use the package.
-They attempt to be representative,
-though not comprehensive.  Further examples can be found in the games section
-of the source tree and in various utilities that use the screen such as 
-.i systat(1) .
-.pp
-The following examples are intended to demonstrate
-the basic structure of a program
-using the package.  An additional, more comprehensive, program can be found in
-the source code in the 
-\fIexamples\fP subdirectory.
-.sh 2 "Simple Character Output"
-.pp
-This program demonstrates how to set up a window and output characters to it.
-Also, it demonstrates how one might control the output to the window.  If
-you run this program, you will get a demonstration of the character output
-chracteristics discussed in the above Character Output section.

-.sh 2 "Twinkle"
-.pp
-This is a moderately simple program which prints
-patterns on the screen.
-It switches between patterns of asterisks,
-putting them on one by one in random order,
-and then taking them off in the same fashion.
-It is more efficient to write this
-using only the motion optimization,
-as is demonstrated below.

-.sh 1 Overview
-.pp
-In making available the generalized terminal descriptions in \*(tc,
-much information was made available to the programmer,
-but little work was taken out of one's hands.
-The purpose of this package is to allow the C programmer
-to do the most common type of terminal dependent functions,
-those of movement optimization and optimal screen updating,
-without doing any of the dirty work,
-and with nearly as much ease as is necessary to simply print
-or read things.
-.sh 2 "Terminology"
-.pp
-In this document, the following terminology is used:
-.de Ip
-.sp
-.in 5n
-.ti 0n
-.b "\\$1" :
-..
-.Ip window
-An internal representation
-containing an image of what a section of the terminal screen may look like
-at some point in time.
-This subsection can either encompass the entire terminal screen,
-or any smaller portion down to a single character within that screen.
-.Ip terminal
-Sometimes called
-.b terminal
-.b screen .
-The package's idea of what the terminal's screen currently looks like,
-.i i.e. ,
-what the user sees now.
-This is a special
-.i screen :
-.Ip screen
-This is a subset of windows which are as large as the terminal screen,
-.i i.e. ,
-they start at the upper left hand corner
-and encompass the lower right hand corner.
-One of these,
-.Vn stdscr ,
-is automatically provided for the programmer.
-.rm Ip
-.sh 2 "Compiling Applications"
-.pp
-In order to use the library,
-it is necessary to have certain types and variables defined.
-Therefore, the programmer must have a line:
-.(l
-.b "#include <curses.h>"
-.)l
-at the top of the program source.
-Compilations should have the following form:
-.(l
-.ie t \fBcc\fR [ \fIflags\fR ] file ... \fB\-lcurses \-ltermcap\fR
-.el \fIcc\fR [ flags ] file ... \fI\-lcurses \-ltermcap\fR
-.)l
-.sh 2 "Screen Updating"
-.pp
-In order to update the screen optimally,
-it is necessary for the routines to know what the screen currently looks like
-and what the programmer wants it to look like next.
-For this purpose,
-a data type
-(structure)
-named
-.Vn WINDOW
-is defined
-which describes a window image to the routines,
-including its starting position on the screen
-(the \*y of the upper left hand corner)
-and its size.
-One of these
-(called
-.Vn curscr
-for
-.i "current screen" )
-is a screen image of what the terminal currently looks like.
-Another screen
-(called
-.Vn stdscr ,
-for
-.i "standard screen" )
-is provided
-by default
-to make changes on.
-.pp
-A window is a purely internal representation.
-It is used to build and store
-a potential image of a portion of the terminal.
-It doesn't bear any necessary relation
-to what is really on the terminal screen.
-It is more like an array of characters on which to make changes.
-.pp
-When one has a window which describes
-what some part the terminal should look like,
-the routine
-.Fn refresh
-(or
-.Fn wrefresh
-if the window is not
-.Vn stdscr )
-is called.
-.Fn Refresh
-makes the terminal,
-in the area covered by the window,
-look like that window.
-Note, therefore, that changing something on a window
-.i does
-.bi not
-.i "change the terminal" .
-Actual updates to the terminal screen
-are made only by calling
-.Fn refresh
-or
-.Fn wrefresh .
-This allows the programmer to maintain several different ideas
-of what a portion of the terminal screen should look like.
-Also, changes can be made to windows in any order,
-without regard to motion efficiency.
-Then, at will,
-the programmer can effectively say
-.q "make it look like this" ,
-and the package will execute the changes in an optimal way.
-.sh 2 "Naming Conventions"
-.pp
-As hinted above,
-the routines can use several windows,
-but two are always available:
-.Vn curscr ,
-which is the image of what the terminal looks like at present, 
-and
-.Vn stdscr ,
-which is the image of what the programmer wants the terminal to look like next.
-The user should not access
-.Vn curscr
-directly.
-Changes should be made to
-the appropriate screen,
-and then the routine
-.Fn refresh
-(or
-.Fn wrefresh )
-should be called.
-.pp
-Many functions are set up to deal with
-.Vn stdscr
-as a default screen.
-For example, to add a character to
-.Vn stdscr ,
-one calls
-.Fn addch
-with the desired character.
-If a different window is to be used,
-the routine
-.Fn waddch
-(for
-.b w indow-specific
-.Fn addch )
-is provided\**.
-.(f
-\**
-Actually,
-.Fn addch
-is really a
-.q #define
-macro with arguments,
-as are most of the "functions" which act upon
-.Vn stdscr .
-.)f
-This convention of prepending function names with a
-.Bq w
-when they are to be applied to specific windows
-is consistent.
-The only routines which do
-.i not
-do this are those
-to which a window must always be specified.
-.pp
-In order to move the current \*y from one point to another,
-the routines
-.Fn move
-and
-.Fn wmove
-are provided.
-However,
-it is often desirable to first move and then perform some I/O operation.
-In order to avoid clumsiness,
-most I/O routines can be preceded by the prefix
-.Bq mv
-and the desired \*y can then be added to the arguments to the function.
-For example,
-the calls
-.(l
-move(y\*,x);
-addch(ch);
-.)l
-can be replaced by
-.(l
-mvaddch(y\*,x\*,ch);
-.)l
-and
-.(l
-wmove(win\*,y\*,x);
-waddch(win\*,ch);
-.)l
-can be replaced by
-.(l
-mvwaddch(win\*,y\*,x\*,ch);
-.)l
-Note that the window description pointer
-.Vn win ) (
-comes before the added \*y.
-If a window pointer is needed, it is always the first parameter passed.

-.sh 1 Usage
-.pp
-This is a description of how to actually use the screen package.
-For simplicity, we assume all updating, reading, etc.
-is applied to
-.Vn stdscr , 
-although a different window can of course be specified.
-.sh 2 "Initialization"
-.pp
-In order to use the screen package,
-the routines must know about terminal characteristics,
-and the space for
-.Vn curscr
-and
-.Vn stdscr
-must be allocated.
-These functions are performed by
-.Fn initscr .
-Since it must allocate space for the windows,
-it can overflow core when attempting to do so.
-On this rather rare occasion,
-.Fn initscr
-returns ERR.
-.Fn Initscr
-must
-.bi always
-be called before any of the routines which affect windows are used.
-If it is not,
-the program will core dump as soon as either
-.Vn curscr
-or
-.Vn stdscr
-are referenced.
-However, it is usually best to wait to call it
-until after you are sure you will need it,
-like after checking for startup errors.
-Terminal status changing routines
-like
-.Fn nl
-and
-.Fn cbreak
-should be called after
-.Fn initscr .
-.pp
-After the initial window allocation done by 
-.Fn initscr ,
-specific window characteristics can be set.
-Scrolling can be enabled by calling
-.Fn scrollok .
-If you want the cursor to be left after the last change, use
-.Fn leaveok .
-If this isn't done,
-.Fn refresh
-will move the cursor to the window's current \*y after updating it.
-Additional windows can be created by using the functions
-.Fn newwin
-and
-.Fn subwin .
-.Fn Delwin
-allows you to delete an exisiting window.
-The variables
-.Vn LINES
-and
-.Vn COLS
-control the size of the terminal.  They are initially implicitly set by 
-.Fn initscr ,
-but can be altered explicitly by the user followed by a call to 
-.Fn initscr .
-Note that any call to 
-.Fn initscr ,
-will always delete any existing
-.Vn stdscr
-and/or
-.Vn curscr
-before creating new ones so this change is best done before the initial call to
-.Fn initscr .
-.pp
-.sh 2 "Output"
-.pp
-The basic functions
-used to change what will go on a window are
-.Fn addch
-and
-.Fn move .
-.Fn Addch
-adds a character at the current \*y,
-returning ERR if it would cause the window to illegally scroll,
-.i i.e. ,
-printing a character in the lower right-hand corner
-of a terminal which automatically scrolls
-if scrolling is not allowed.
-.Fn Move
-changes the current \*y to whatever you want them to be.
-It returns ERR if you try to move off the window.
-As mentioned above, you can combine the two into
-.Fn mvaddch
-to do both things in one call.
-.pp
-The other output functions 
-(such as
-.Fn addstr
-and
-.Fn printw )
-all call
-.Fn addch
-to add characters to the window.
-.pp
-After a change has been made to the window,
-you must call 
-.Fn refresh .
-when you want the portion of the terminal covered by the window
-to reflect the change.
-In order to optimize finding changes,
-.Fn refresh
-assumes that any part of the window not changed
-since the last
-.Fn refresh
-of that window has not been changed on the terminal,
-.i i.e. ,
-that you have not refreshed a portion of the terminal
-with an overlapping window.
-If this is not the case,
-the routines
-.Fn touchwin ,
-.Fn touchline ,
-and
-.Fn touchoverlap
-are provided to make it look like a desired part of window has been changed,
-thus forcing
-.Fn refresh
-to check that whole subsection of the terminal for changes.
-.pp
-If you call
-.Fn wrefresh
-with
-.Vn curscr ,
-it will make the screen look like the image of 
-.Vn curscr .
-This is useful for implementing a command
-which would redraw the screen in case it got messed up.
-.sh 2 Input
-.pp
-Input is essentially a mirror image of output.
-The complementary function to
-.Fn addch
-is
-.Fn getch
-which,
-if echo is set,
-will call
-.Fn addch
-to echo the character.
-Since the screen package needs to know what is on the terminal at all times,
-if characters are to be echoed,
-the tty must be in raw or cbreak mode.
-If it is not,
-.Fn getch
-sets it to be cbreak,
-and then reads in the character.
-.sh 2 "Termination"
-.pp
-In order to perform certain optimizations,
-and, 
-on some terminals,
-to work at all,
-some things must be done
-before the screen routines start up.
-These functions are performed in
-.Fn getttmode
-and
-.Fn setterm ,
-which are called by
-.Fn initscr .
-In order to clean up after the routines,
-the routine
-.Fn endwin
-is provided.
-It restores tty modes to what they were
-when
-.Fn initscr
-was first called.
-The terminal state module uses the variable 
-.Vn curses_termios
-to save the original terminal state which is then restored upon a call to 
-.Fn endwin .
-Thus,
-anytime after the call to initscr,
-.Fn endwin
-should be called before exiting.  Note however, that 
-.Fn endwin 
-should always be called 
-.b before
-the final calls to
-.Fn delwin ,
-which free the storage of the windows.

-.sh 1 "Cursor Movement Optimizations"
-.pp
-One of the most difficult things to do properly is motion optimization.
-After using
-.Fn gettmode
-and
-.Fn setterm
-to get the terminal descriptions,
-the function
-.Fn mvcur
-deals with this task.
-It usage is simple:
-simply tell it where you are now and where you want to go.
-For example
-.(l
-mvcur(0\*,0\*,LINES/2\*,COLS/2);
-.)l
-.lp
-would move the cursor from the home position (0\*,0)
-to the middle of the screen.
-If you wish to force absolute addressing,
-you can use the function
-.Fn tgoto
-from the
-.b termlib (7)
-routines,
-or you can tell
-.Fn mvcur
-that you are impossibly far away,
-For example,
-to absolutely address the lower left hand corner of the screen
-from anywhere
-just claim that you are in the upper right hand corner:
-.(l
-mvcur(0\*,COLS\-1\*,LINES\-1\*,0);
-.)l

-.sh 1 "Character Output and Scrolling"
-.pp
-The character output policy deals with the following problems.  First,
-where is the location of the cursor after a character is printed, and 
-secondly, when does the screen scroll if scrolling is enabled.
-.pp
-In the normal case the characters are output as expected, with the cursor 
-occupying the position of the next character to be output.  However, when the
-cursor is on the last column of the line, the cursor will remain on that 
-position after the last character on the line is output and will only assume
-the position on the next line when the next character (the first on the next
-line) is output.
-.pp
-Likewise, if scrolling is enabled, a scroll will be invoked only when the
-first character on he first line past the bottom line of the window is
-output.  If scrolling is not enabled the chracters will to be output to the
-bottom right corner of the window which is the cursor location.
-.pp
-This policy allows consistent behavior of the cursor at the boundary 
-conditions.  Furthermore, it prevents a scroll from happening before it is
-actually needed (the old package used to scroll when the bottom right position
-was output a character).  As a precendent, it models the 
-.i xterm
-character output conventions.
-.sh 1 "Terminal State Handling"
-.pp
-The variable
-.Vn curses_termios
-contains the terminal state of the terminal.  Certain historical routines 
-return information:
-.Fn baudrate , 
-.Fn erasechar ,
-.Fn killchar ,
-and 
-.Fn ospeed .
-These routines are obsolete and exist only for backward compatibility.  If
-you wish to use the information in the 
-.Vn curses_termios
-structure, you should use the
-\fItsetattr\fP(3) 
-routines.
-.sh 1 "Subwindows"
-.pp
-Subwindows are windows which do not have an independent text structure, 
-.i i.e. , 
-they are windows whose text is a subset of the text of a larger window: the
-.i parent 
-window.  One consequence of this is that changes to either the parent or the
-child window are destructive to the other, 
-.i i.e. , 
-a change to the subwindow is also a change to the parent window and a change 
-to the parent window in the region defined by the subwindow is implicitly a 
-change to the subwindow as well.
-Apart from this detail, subwindows function like any other window.

-.Sh NAME
-.Nm curses
-.Nd screen functions with ``optimal'' cursor motion
-.Sh SYNOPSIS
-.Nm cc
-.Op Ar flags
-.Ar files
-.Fl lcurses ltermcap
-.Op Ar libraries
-.Sh DESCRIPTION
-These routines give the user a method of updating screens with reasonable
-optimization.  They keep an image of the current screen,
-and the user sets up an image of a new one.  Then the
-.Fn refresh
-tells the routines to make the current screen look like the new one.
-In order to initialize the routines, the routine
-.Fn initscr
-must be called before any of the other routines that deal with windows and
-screens are used.  The routine
-.Fn endwin
-should be called before exiting.

-	 *     the next period is started from cur_period + 1 which is
-	 *     guaranteed not to have been reached since that would mean that
-	 *     all records would have been reached. (think about it...).
-	 *
-	 * Lines in the rotation can have 3 attributes which are marked on the
-	 * line so that curscr is consistent with the visual screen.
-	 * 1.  Not dirty -- lines inside the scrolled block, top region or
-	 *                  bottom region.

-	 *		      region adjacent to top and bot regions
