        the interrupt had not occurred, after the handler exits.
 
 
 
    timeout/wtimeout
            The timeout and wtimeout routines set blocking or non-blocking read for
-       a  given  window.   If  delay is negative, blocking read is used (i.e.,
-       waits indefinitely for input).  If delay  is  zero,  then  non-blocking

+       waits  indefinitely  for  input).   If delay is zero, then non-blocking
        read is used (i.e., read returns ERR if no input is waiting).  If delay
-       is positive, then read blocks for delay milliseconds, and  returns  ERR
-       if  there  is  still  no input.  Hence, these routines provide the same

+       if there is still no input.  Hence, these  routines  provide  the  same
+       functionality  as nodelay, plus the additional capability of being able
        to block for only delay milliseconds (where delay is positive).
 
 
 
    typeahead
            The curses library does "line-breakout optimization" by looking for ty-
        peahead periodically while updating the screen.  If input is found, and
-       it  is  coming  from  a  tty, the current update is postponed until re-
-       fresh(3x) or doupdate is called again.  This allows faster response  to
-       commands  typed in advance.  Normally, the input FILE pointer passed to
+       it is coming from a tty, the current  update  is  postponed  until  re-
+       fresh(3x)  or doupdate is called again.  This allows faster response to
+       commands typed in advance.  Normally, the input FILE pointer passed  to
        newterm, or stdin in the case that initscr was used, will be used to do
        this typeahead checking.  The typeahead routine specifies that the file
-       descriptor fd is to be used to check for typeahead instead.  If  fd  is
+       descriptor  fd  is to be used to check for typeahead instead.  If fd is
        -1, then no typeahead checking is done.

+       All routines that return an integer return  ERR  upon  failure  and  OK
        (SVr4 specifies only "an integer value other than ERR") upon successful

    EXTENSIONS
    +       This implementation provides four functions which may be used to detect
+       if the corresponding flags were set or reset:
+
+       Query       Set      Reset
+       ----------------------------------
+       is_cbreak   cbreak   nocbreak
+       is_echo     echo     noecho
+       is_nl       nl       nonl
+       is_raw      raw      noraw
+
+       In each case, the function returns
+
+       1    if the flag is set,
+
+       0    if the flag is reset, or
+
+       -1   if the curses library was not initialized.
+
+       These  routines  are  specific  to ncurses.  They were not supported on
+       Version 7, BSD or System V implementations.  It is recommended that any
+       code  depending on ncurses extensions be conditioned using NCURSES_VER-
+       SION.
 
 
 
    PORTABILITY
    -       These functions are described in the XSI Curses standard, Issue 4.

        The ncurses library obeys the XPG4 standard and the historical practice

-       when curses initializes the terminal state.  BSD curses  differed  from
-       this  slightly;  it left the echo bit on at initialization, but the BSD
-       raw call turned it off as a side-effect.   For  best  portability,  set

        gram remains in cooked mode.
 
-       The XSI Curses standard is ambiguous on the  question  of  whether  raw
-       should  disable  the  CRLF translations controlled by nl and nonl.  BSD
-       curses did turn off these translations; AT&T curses (at least  as  late
-       as  SVr1)  did not.  We chose to do so, on the theory that a programmer
-       requesting raw input wants a clean  (ideally  8-bit  clean)  connection

        When keypad is first enabled, ncurses loads the key-definitions for the
        current terminal description.  If the terminal description includes ex-

        Low-level applications can use tigetstr to obtain the definition of any

        Most curses implementations (including ncurses) load key definitions in

        later definition is the one used.
