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.
