+.sh 1 "The WINDOW structure"
+.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 .

+.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 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 3 "A Small Screen Manipulator"

+The next example follows the lines of the previous one but extends then to 
+demonstrate the various othe uses of the package.  Make sure you understand 
+how this program works as it encompasses most of anything you will
+need to do with the package.
+.(l I
+.so t3.gr

+.sh 3 "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.
+.(l I
+.so twinkle1.gr
+.)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):

+.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.
