+
+### Description
+
+   cbreak() and nocbreak() toggle cbreak mode. In cbreak mode,
+   characters typed by the user are made available immediately, and
+   erase/kill character processing is not performed. In nocbreak mode,
+   typed characters are buffered until a newline or carriage return.
+   Interrupt and flow control characters are unaffected by this mode.
+   PDCurses always starts in cbreak mode.
+
+   echo() and noecho() control whether typed characters are echoed by
+   the input routine. Initially, input characters are echoed. Subsequent
+   calls to echo() and noecho() do not flush type-ahead.
+
+   halfdelay() is similar to cbreak(), but allows for a time limit to be
+   specified, in tenths of a second. This causes getch() to block for
+   that period before returning ERR if no key has been received. tenths
+   must be between 1 and 255.
+
+   keypad() controls whether getch() returns function/special keys as
+   single key codes (e.g., the left arrow key as KEY_LEFT). Per X/Open,
+   the default for keypad mode is OFF. You'll probably want it on. With
+   keypad mode off, if a special key is pressed, getch() does nothing or
+   returns ERR.
+
+   nodelay() controls whether wgetch() is a non-blocking call. If the
+   option is enabled, and no input is ready, wgetch() will return ERR.
+   If disabled, wgetch() will hang until input is ready.
+
+   nl() enables the translation of a carriage return into a newline on
+   input. nonl() disables this. Initially, the translation does occur.
+
+   raw() and noraw() toggle raw mode. Raw mode is similar to cbreak
+   mode, in that characters typed are immediately passed through to the
+   user program. The difference is that in raw mode, the INTR, QUIT,
+   SUSP, and STOP characters are passed through without being
+   interpreted, and without generating a signal.
+
+   In PDCurses, the meta() function sets raw mode on or off.
+
+   timeout() and wtimeout() set blocking or non-blocking reads for the
+   specified window. If the delay is negative, a blocking read is used;
+   if zero, then non-blocking reads are done -- if no input is waiting,
+   ERR is returned immediately. If the delay is positive, the read
+   blocks for the delay period; if the period expires, ERR is returned.
+   The delay is given in milliseconds, but this is rounded down to 50ms
+   (1/20th sec) intervals, with a minimum of one interval if a postive
+   delay is given; i.e., 1-99 will wait 50ms, 100-149 will wait 100ms,
+   etc.
+
+   wgetdelay() returns the delay timeout as set in wtimeout().
+
+   intrflush(), notimeout(), noqiflush(), qiflush() and typeahead() do
+   nothing in PDCurses, but are included for compatibility with other
+   curses implementations.
+
+   crmode() and nocrmode() are archaic equivalents to cbreak() and
+   nocbreak(), respectively.
+
+   is_keypad() reports whether the specified window is in keypad mode.
+
+   is_nodelay() reports whether the specified window is in nodelay mode.
+
+### Return Value
+
+   is_keypad() and is_nodelay() return TRUE or FALSE. is_notimeout() is
+   provided for compatibility with other curses implementations, and
+   always returns FALSE. All others return OK on success and ERR on error.
