The <STRONG>cbreak</STRONG> routine - disables line buffering and erase/kill character-process- - ing (interrupt and flow control characters are unaf- - fected), making characters typed by the user immediately - available to the program. The <STRONG>nocbreak</STRONG> routine returns - the terminal to normal (cooked) mode. - - Initially the terminal may or may not be in <STRONG>cbreak</STRONG> mode, - as the mode is inherited; therefore, a program should call - <STRONG>cbreak</STRONG> or <STRONG>nocbreak</STRONG> explicitly. Most interactive programs - using <STRONG>curses</STRONG> set the <STRONG>cbreak</STRONG> mode. Note that <STRONG>cbreak</STRONG> over- - rides <STRONG>raw</STRONG>. [See <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG> for a discussion of how - these routines interact with <STRONG>echo</STRONG> and <STRONG>noecho</STRONG>.] - - The <STRONG>echo</STRONG> and <STRONG>noecho</STRONG> routines control whether characters - typed by the user are echoed by <STRONG>getch</STRONG> as they are typed. - Echoing by the tty driver is always disabled, but ini- - tially <STRONG>getch</STRONG> is in echo mode, so characters typed are - echoed. Authors of most interactive programs prefer to do - their own echoing in a controlled area of the screen, or - not to echo at all, so they disable echoing by calling - <STRONG>noecho</STRONG>. [See <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG> for a discussion of how these - routines interact with <STRONG>cbreak</STRONG> and <STRONG>nocbreak</STRONG>.] - - The <STRONG>halfdelay</STRONG> routine is used for half-delay mode, which - is similar to <STRONG>cbreak</STRONG> mode in that characters typed by the - user are immediately available to the program. However, - after blocking for <EM>tenths</EM> tenths of seconds, ERR is - returned if nothing has been typed. The value of <STRONG>tenths</STRONG> - must be a number between 1 and 255. Use <STRONG>nocbreak</STRONG> to leave - half-delay mode. - - If the <STRONG>intrflush</STRONG> option is enabled, (<EM>bf</EM> is <STRONG>TRUE</STRONG>), when an - interrupt key is pressed on the keyboard (interrupt, - break, quit) all output in the tty driver queue will be - flushed, giving the effect of faster response to the - interrupt, but causing <STRONG>curses</STRONG> to have the wrong idea of - what is on the screen. Disabling (<EM>bf</EM> is <STRONG>FALSE</STRONG>), the - option prevents the flush. The default for the option is - inherited from the tty driver settings. The window argu- - ment is ignored. - - The <STRONG>keypad</STRONG> option enables the keypad of the user's termi- - nal. If enabled (<EM>bf</EM> is <STRONG>TRUE</STRONG>), the user can press a func- - tion key (such as an arrow key) and <STRONG>wgetch</STRONG> returns a sin- - gle value representing the function key, as in <STRONG>KEY_LEFT</STRONG>. - If disabled (<EM>bf</EM> is <STRONG>FALSE</STRONG>), <STRONG>curses</STRONG> does not treat function - keys specially and the program has to interpret the escape - sequences itself. If the keypad in the terminal can be - turned on (made to transmit) and off (made to work - locally), turning on this option causes the terminal key- - pad to be turned on when <STRONG>wgetch</STRONG> is called. The default - value for keypad is false. - - Initially, whether the terminal returns 7 or 8 significant - bits on input depends on the control mode of the tty - driver [see <STRONG><A HREF="termio.7.html">termio(7)</A></STRONG>]. To force 8 bits to be returned, - invoke <STRONG>meta</STRONG>(<EM>win</EM>, <STRONG>TRUE</STRONG>); this is equivalent, under POSIX, - to setting the CS8 flag on the terminal. To force 7 bits - to be returned, invoke <STRONG>meta</STRONG>(<EM>win</EM>, <STRONG>FALSE</STRONG>); this is equiva- - lent, under POSIX, to setting the CS7 flag on the termi- - nal. The window argument, <EM>win</EM>, is always ignored. If the - terminfo capabilities <STRONG>smm</STRONG> (meta_on) and <STRONG>rmm</STRONG> (meta_off) are - defined for the terminal, <STRONG>smm</STRONG> is sent to the terminal when - <STRONG>meta</STRONG>(<EM>win</EM>, <STRONG>TRUE</STRONG>) is called and <STRONG>rmm</STRONG> is sent when <STRONG>meta</STRONG>(<EM>win</EM>, - <STRONG>FALSE</STRONG>) is called. - - The <STRONG>nodelay</STRONG> option causes <STRONG>getch</STRONG> to be a non-blocking call. - If no input is ready, <STRONG>getch</STRONG> returns <STRONG>ERR</STRONG>. If disabled (<EM>bf</EM> - is <STRONG>FALSE</STRONG>), <STRONG>getch</STRONG> waits until a key is pressed. - - While interpreting an input escape sequence, <STRONG>wgetch</STRONG> sets a - timer while waiting for the next character. If <STRONG>notime-</STRONG> - <STRONG>out(</STRONG><EM>win</EM>, <STRONG>TRUE</STRONG>) is called, then <STRONG>wgetch</STRONG> does not set a - timer. The purpose of the timeout is to differentiate - between sequences received from a function key and those - typed by a user. - - The <STRONG>raw</STRONG> and <STRONG>noraw</STRONG> routines place the terminal into or out - of raw mode. Raw mode is similar to <STRONG>cbreak</STRONG> mode, in that - characters typed are immediately passed through to the - user program. The differences are that in raw mode, the - interrupt, quit, suspend, and flow control characters are - all passed through uninterpreted, instead of generating a - signal. The behavior of the BREAK key depends on other - bits in the tty driver that are not set by <STRONG>curses</STRONG>. - - When the <STRONG>noqiflush</STRONG> routine is used, normal flush of input - and output queues associated with the <STRONG>INTR</STRONG>, <STRONG>QUIT</STRONG> and <STRONG>SUSP</STRONG> - characters will not be done [see <STRONG><A HREF="termio.7.html">termio(7)</A></STRONG>]. When <STRONG>qiflush</STRONG> - is called, the queues will be flushed when these control - characters are read. You may want to call <STRONG>noqiflush()</STRONG> in - a signal handler if you want output to continue as though - the interrupt had not occurred, after the handler exits. - - The <STRONG>timeout</STRONG> and <STRONG>wtimeout</STRONG> routines set blocking or non- - blocking read for a given window. If <EM>delay</EM> is negative, - blocking read is used (<EM>i</EM>.<EM>e</EM>., waits indefinitely for - input). If <EM>delay</EM> is zero, then non-blocking read is used - (<EM>i</EM>.<EM>e</EM>., read returns <STRONG>ERR</STRONG> if no input is waiting). If <EM>delay</EM> - is positive, then read blocks for <EM>delay</EM> milliseconds, and - returns <STRONG>ERR</STRONG> if there is still no input. Hence, these rou- - tines provide the same functionality as <STRONG>nodelay</STRONG>, plus the - additional capability of being able to block for only - <EM>delay</EM> milliseconds (where <EM>delay</EM> is positive). - - The <STRONG>curses</STRONG> library does ``line-breakout optimization'' by - looking for typeahead periodically while updating the - screen. If input is found, and it is coming from a tty, - the current update is postponed until <STRONG>refresh</STRONG> or <STRONG>doupdate</STRONG> - is called again. This allows faster response to commands - typed in advance. Normally, the input FILE pointer passed - to <STRONG>newterm</STRONG>, or <STRONG>stdin</STRONG> in the case that <STRONG>initscr</STRONG> was used, - will be used to do this typeahead checking. The <STRONG>typeahead</STRONG> - routine specifies that the file descriptor <EM>fd</EM> is to be - used to check for typeahead instead. If <EM>fd</EM> is -1, then no - typeahead checking is done. - - -</PRE> -<H2>RETURN VALUE</H2><PRE> - All routines that return an integer return <STRONG>ERR</STRONG> upon fail- - ure and OK (SVr4 specifies only "an integer value other - than <STRONG>ERR</STRONG>") upon successful completion, unless otherwise - noted in the preceding routine descriptions. - - -</PRE> -<H2>PORTABILITY</H2><PRE> - These functions are described in the XSI Curses standard, - Issue 4. - - The ncurses library obeys the XPG4 standard and the his- - torical practice of the AT&T curses implementations, in - that the echo bit is cleared when curses initializes the - terminal state. BSD curses differed from this slightly; - it left the echo bit on at initialization, but the BSD <STRONG>raw</STRONG> - call turned it off as a side-effect. For best portabil- - ity, set echo or noecho explicitly just after initializa- - tion, even if your program remains in cooked mode. - - -</PRE> -<H2>NOTES</H2><PRE> - Note that <STRONG>echo</STRONG>, <STRONG>noecho</STRONG>, <STRONG>halfdelay</STRONG>, <STRONG>intrflush</STRONG>, <STRONG>meta</STRONG>, <STRONG>node-</STRONG> - <STRONG>lay</STRONG>, <STRONG>notimeout</STRONG>, <STRONG>noqiflush</STRONG>, <STRONG>qiflush</STRONG>, <STRONG>timeout</STRONG>, and <STRONG>wtimeout</STRONG> - may be macros. - - The <STRONG>noraw</STRONG> and <STRONG>nocbreak</STRONG> calls follow historical practice in - that they attempt to restore to normal (`cooked') mode - from raw and cbreak modes respectively. Mixing raw/noraw - and cbreak/nocbreak calls leads to tty driver control - states that are hard to predict or understand; it is not - recommended. - - -</PRE> -<H2>SEE ALSO</H2><PRE> - <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG>, <STRONG><A HREF="curs_initscr.3x.html">curs_initscr(3x)</A></STRONG>, <STRONG><A HREF="termio.7.html">termio(7)</A></STRONG> - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -</PRE> -<HR> -<ADDRESS> -Man(1) output converted with -<a href="http://www.oac.uci.edu/indiv/ehood/man2html.html">man2html</a> -</ADDRESS> -</BODY> -</HTML> |
