+
+ 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. The delay is measured in milliseconds. If
+ it's 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.
+
+ 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.
+
+ Return Value:
+ All functions return OK on success and ERR on error.
