-.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 characters will 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 a character was
-written to the right-most position on the last line). As a precedent, 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.
