+.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 .
